If a line on your bill of materials reads X5R, 10 µF, from a Japanese or Korean capacitor maker, that part now sits in a segment its manufacturer is deliberately shrinking. According to TrendForce Taiwan (2026), Murata is reported to have sent its global customers an annual discontinuation notice on September 10, 2026, covering generic consumer multilayer ceramic capacitors and certain standard automotive references, with order cutoff in 2028 and final shipments in 2029 (source).
That timeline comes from TrendForce's market analysis. No public end-of-life bulletin from the manufacturer and no regulatory filing were identified to confirm it independently, so treat the dates as a planning horizon rather than a contractual deadline. The direction of travel, however, is consistent across every TrendForce publication from July to September 2026: capacity is moving toward AI servers and away from the commodity references that fill most industrial boards.
What Changed in 2026, and Who Is Exposed?
The short answer: Japanese and Korean MLCC makers are reallocating production from consumer-grade X5R parts toward X6S and X7R high-end specifications for AI servers and data centers MLCC Prices September 2026: Standard Down, AI-Grade Up 105%, according to TrendForce (July 2026, source). Any OEM or EMS provider buying mid-to-high capacitance consumer-grade or standard automotive-grade MLCCs from Murata, Samsung Electro-Mechanics or Taiyo Yuden is directly affected.
The timing matters. TrendForce reports the shift was already visible in mid-2026 shipment data, and its August 2026 bulletin estimates that tightness on high-end parts could extend into 2027 (source).
Read this as a bifurcation of supply. Overall MLCC output is holding up; what is contracting is the specific slice of capacity that most consumer electronics and conventional automotive designs depend on. Procurement teams that frame this as "a general MLCC shortage" will misallocate effort. The problem is concentrated in defined specification ranges, which means the response can be targeted too.
What Did the MLCC Supply Landscape Look Like Before This Shift?
Before this shift, the leading Japanese and Korean suppliers served both commodity consumer electronics and high-reliability segments, and buyers of standard-grade parts had little reason to expect those lines to be wound down. TrendForce's September 2026 analysis describes this as a structural change: suppliers are reducing consumer-oriented supply and prioritizing high-end AI specifications, including high-capacitance and miniaturized formats for AI servers, data centers and certain automotive systems (source).
The trigger is demand. TrendForce reports that AI server orders HBM4 Prices Up 121% in 2027: What OEM and EMS Buyers Must Plan For pushed the combined monthly shipments of Murata, Samsung Electro-Mechanics and Taiyo Yuden to their highest level in five years in June 2026 (source). When a manufacturer's most demanding customers absorb record volumes, capacity decisions follow the margin.
That margin logic is explicit in TrendForce Taiwan's September 17, 2026 bulletin, which states that Murata is phasing out low-margin conventional MLCCs to concentrate on high-end AI and automotive specifications (source). The capacity range taking the hit is well defined: TrendForce's July 2026 analysis identifies consumer-grade MLCCs in the 1 to 22 µF range as the segment under the strongest compression.
For a buyer, the practical lesson from this history is uncomfortable. Parts that never appeared on an obsolescence watch list, because they were produced by the largest suppliers in the world, are now the ones with a visible runway.
What Exactly Is Changing? Specifications, Lead Times and Timelines
Which specifications are being phased down, and which are prioritized?
Phased down: X5R consumer-grade dielectrics, generic consumer MLCCs and standard automotive-grade references, per TrendForce (2026). Prioritized: X6S and X7R high-end specifications built for AI servers, data centers and advanced automotive electronics.
The dielectric distinction is the practical screening tool. X5R dielectrics are rated for a narrower operating temperature range than X7R and X6S, which extend the operating envelope and are specified where thermal stability under sustained load is non-negotiable. If your design uses X5R parts in positions where an X7R part of the same capacitance and footprint would meet the electrical requirement, you may have a substitution path. If the X5R part was chosen for its higher capacitance density in a small case size, the path is narrower.
How long are lead times stretching?
TrendForce reported in August 2026 that high-end MLCC lead times had reached approximately 5 to 10 months MLCC Prices September 2026: Standard Down, AI-Grade Up 105% on AI-driven demand, while standard products were moving on a different trajectory (source). TrendForce estimates this tightness could persist into 2027.
The divergence is the key word. A buyer sourcing both an X7R high-end part for a power stage and an X5R commodity part for decoupling faces two different problems on the same purchase order: a long wait on the first, and a shrinking production base on the second.
What is the discontinuation timeline for affected references?
Per TrendForce Taiwan's reading of the Murata notification (September 2026), order cutoff falls around 2028 and last shipments around 2029. TrendForce Taiwan's September 30, 2026 bulletin describes a roughly three-year transition period during which Taiwanese and mainland Chinese suppliers may absorb conventional orders (source).
Three years sounds comfortable. It is not, once you subtract the time required to qualify an alternate source, run reliability testing, update approved vendor lists, and requalify the finished assembly with your own customers. For automotive programs with PPAP requirements, the available margin is thinner still.
Who verifies these changes?
All of the above originates from TrendForce. No independent confirmation from a regulator or from the manufacturers' public documentation surfaced in the available research. Build your plan on the TrendForce horizon, then verify reference by reference with your franchised distributor's product change notifications as they arrive.
How Is the Supplier Map Being Redrawn? Chinese Manufacturers Enter Qualification
The capacity vacated by Japanese and Korean makers is attracting new entrants. TrendForce's September 10, 2026 MLCC Market Bulletin reports that HP, ASUS, Acer, Quanta and Pegatron have begun validating Chinese MLCC suppliers, and its September 24 analysis adds Dell to the list of global brands running qualification processes (source and source). TrendForce also added CCTC to its MLCC supplier tracking list in the same bulletin, a sign of growing analyst attention to the Chinese side of the market.
Qualification and adoption are different stages. In qualification, components undergo technical and reliability evaluation before any volume commercial referencing. It does not confirm a final design-in, and it says nothing about field reliability data over several years, which most industrial customers will demand before approving a substitute.
Where Chinese suppliers gain ground, according to TrendForce Taiwan (2026): general-purpose servers, consumer electronics and entry-level automotive applications. Where they remain disadvantaged: top-tier AI-server MLCCs, where TrendForce's September 10 bulletin notes that high-end yield remains a challenge.
TrendForce frames the outcome as a redistribution of opportunity, with Japanese and Korean leaders retaining the most demanding AI segments. For a procurement director, the implication is that the "alternate source" for a discontinued commodity part will increasingly carry a Chinese or Taiwanese logo, and that the burden of verifying its documentation lands on the buyer.
What Does This Mean for OEMs and EMS Providers Managing Production Continuity?
Direct exposure is now quantifiable. If your approved vendor list for standard automotive-grade or generic consumer MLCCs is built on Japanese and Korean suppliers, you are looking at a discontinuation runway of roughly 2028 to 2029 NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028 per TrendForce Taiwan (2026), on parts that may appear on hundreds of assemblies.
The cost of inaction compounds quietly. Waiting for the formal end-of-life notice from your distributor compresses the window for a last-time-buy decision, for redesign qualification and for alternate-source validation into a much shorter period, usually while competitors are placing the same last-time-buy orders on the same remaining capacity.
Pricing is sending a second signal. TrendForce Taiwan's September 30, 2026 bulletin reports that low-end MLCC prices declined as consumer-electronics demand weakened, while high-end AI-server MLCC supply stayed tight and prices remained elevated MLCC Prices September 2026: Standard Down, AI-Grade Up 105% (source). Budget assumptions built on historical pricing for high-spec references should be revisited before the next annual negotiation.
Industrial buyers therefore carry a dual risk. On one side, finding compliant alternates for standard-grade parts that are being phased out. On the other, securing allocation for high-end AI or automotive-grade MLCCs where lead times already stretch to 5 to 10 months per TrendForce (August 2026) HBM4 Prices Up 121% in 2027: What OEM and EMS Buyers Must Plan For. Both land on the same desk, and both are easy to defer because neither has caused a line stoppage yet.
Traceability is the risk that gets underestimated. As new sources enter qualification, demand verified documentation on origin and quality control before accepting a substitute. A qualification announcement at a global PC brand does not transfer to your application, your temperature profile or your customer's reliability requirements. Every substitute needs its own paper trail: certificate of conformance, lot and date code traceability, and inspection results against the datasheet.
How Can Specialized Sourcing Bridge the MLCC Allocation Gap?
Consider a concrete case. An EMS provider builds an automotive sensor module for a Tier 1 customer. The design uses a standard automotive-grade MLCC from a Japanese supplier, and the reference now falls within the scope TrendForce Taiwan associates with a 2028 order cutoff. The customer has not approved any drop-in replacement, requalification of the module is a lengthy multi-step process, and annual volume runs to several million pieces.
The practical response has two tracks running in parallel. The first is securing physical stock of the exact discontinued reference, enough to cover production until a validated alternate is approved. The second is qualifying that alternate, whether a higher-grade part from the same manufacturer or a Taiwanese or Chinese source entering the market during the transition window TrendForce describes.
This is the situation in which a specialized shortage broker becomes relevant to a large industrial account. The work consists of locating physical inventory of a specific reference across international channels, then qualifying each source before any commitment: confirming the stock exists, verifying date codes and packaging, checking documentation against the original manufacturer's specifications and arranging independent inspection where the chain of custody is incomplete. Firms such as Origin Sourcing operate on this model, with each critical request assessed individually and arbitrated between availability, traceability, lead time and risk, with management directly involved in the decision.
Take a position on the trade-off. When the production line is weeks from a stop, exact-reference stock with full traceability is worth more than a cheaper untested substitute. When the horizon is two years and the redesign is funded, qualifying the alternate first and buying only a bridge quantity is the better use of budget. Avoid the middle path of buying large quantities of an unverified substitute because it was available; that converts a supply problem into a quality problem.
The timeline TrendForce lays out for 2028 and 2029 is a planning asset. Used now, it gives procurement teams time to map exposure by reference, decide where to redesign and where to bridge, and lock in stock while it still exists in franchised channels. Used later, it becomes the date on an escalation email.
FAQ
Are all MLCCs becoming scarce in 2026?
No. TrendForce (2026) describes a bifurcation: high-end X6S and X7R MLCCs for AI servers face lead times of roughly 5 to 10 months, while capacity for consumer-grade X5R parts in the 1 to 22 µF range is being cut as suppliers reallocate production. Scarcity is concentrated in specific specification ranges, not spread evenly across the category.
When will discontinued consumer and standard automotive MLCCs stop shipping?
According to TrendForce Taiwan's analysis of the Murata notification (September 2026), order cutoff is expected around 2028 and last shipments around 2029. These dates come from analyst reporting and have not been independently confirmed by a manufacturer or regulatory publication, so they should be used as a planning horizon and verified per reference.
Can Chinese MLCC suppliers replace Japanese and Korean parts immediately?
Not yet at scale. TrendForce (September 2026) reports that brands including Dell, HP, ASUS, Acer, Quanta and Pegatron have begun qualifying Chinese suppliers, but qualification precedes adoption and does not provide long-term reliability data. TrendForce also notes that high-end AI-server yield remains a challenge for Chinese entrants.
What should a procurement team do first?
Map every MLCC on the approved vendor list against the affected specification ranges identified by TrendForce (X5R consumer-grade, 1 to 22 µF, standard automotive-grade from Japanese and Korean makers). Then rank by annual consumption and redesign difficulty, and open last-time-buy and alternate-qualification discussions for the top of that list before formal end-of-life notices arrive.
How should substitutes from new sources be verified?
Require full documentation on each lot: certificate of conformance, date and lot code traceability back to the manufacturer, and inspection results against the datasheet. Where the chain of custody is incomplete, arrange independent testing before release to production. A qualification announcement at another OEM does not substitute for verification in your own application.
