TL;DR — 세 문장

  • Murata is discontinuing selected MLCC part numbers across nine series: GRM, GRJ, GRT, GXM, GXT, GCM, GCJ, GCG and ZRA (S1).
  • Deadlines: customer review by December 31, 2027; last orders March 31, 2028; final shipments through March 31, 2029 (S1).
  • The change covers individual part numbers, not whole series, and is not a Murata exit from the MLCC market (S1).

Reported by Electronics Era on 2026-10-10. Summarized and analyzed by XAIPART Editorial.

What happened

Murata Manufacturing is preparing to discontinue selected MLCC part numbers across nine product series, according to a customer notification circulating in the electronics supply chain.S1 The affected series are GRM, GRJ, GRT, GXM, GXT, GCM, GCJ, GCG and ZRA.S1

The change covers individual part numbers rather than the product series as a whole, and the source states it does not represent a withdrawal by Murata from the MLCC market; Murata continues to offer a broad portfolio including automotive, high-reliability and high-capacitance products.S1 Customers have until December 31, 2027 to complete the relevant review and confirmation. The reported last order date is March 31, 2028, followed by final shipments through March 31, 2029.S1

The notification fits a broader capacity-allocation picture. TrendForce reported in July that the book-to-bill ratios of Murata, Samsung Electro-Mechanics and Taiyo Yuden had reached 1.30, 1.31 and 1.25, respectively, by late June 2026, the highest since the pandemic period, and that the three companies' shipments hit a five-year monthly high in June while some capacity shifted toward MLCCs used in AI applications.S1

Background timeline

  1. - TrendForce reported book-to-bill ratios of 1.30 (Murata), 1.31 (Samsung Electro-Mechanics) and 1.25 (Taiyo Yuden), the highest for the three companies since the pandemic period; shipments from the three reached a five-year monthly high in June S1

  4. - Reported last order date for the affected part numbers S1
  5. - Final shipments through this date S1

XAIPART take

Technical impact

Replacement MLCCs must be checked against capacitance, tolerance, rated voltage, case size, dielectric, temperature characteristics, DC-bias performance and, where mechanical stress matters, termination construction.S1 Even a numerically identical capacitor from another vendor can behave differently under DC bias or board flex, so a drop-in swap is rarely guaranteed.

Market impact

The source describes general-purpose MLCC supply coming under pressure as capacity moves toward AI-server applications, so a qualified second source may not be easy to secure even where parts appear available.S1 Automotive and industrial users face supplier-change qualification cycles — reliability testing, engineering approval and customer qualification — that can stretch well beyond commercial product timelines.S1 The source did not disclose how many individual part numbers are affected, so BOM exposure must be confirmed against Murata's official notification.

Action

Screen every BOM against the nine listed series (GRM, GRJ, GRT, GXM, GXT, GCM, GCJ, GCG, ZRA) before the December 31, 2027 review deadline. For confirmed hits, place last-time-buy quantities ahead of the March 31, 2028 order cutoff and start second-source qualification in parallel, prioritizing long-lifecycle automotive and industrial lines where requalification is slowest.

XAIPART Forecast

XAIPART expects qualified alternate-source demand for mainstream GRM-family capacitance/voltage/size combinations to rise sharply, and lead times for selected general-purpose MLCC replacements to exceed 12 weeks for at least one major distributor within 6 months of the December 31, 2027 confirmation deadline (i.e., by 2028-06-30); if quoted lead times for mainstream GRM equivalents remain at or below 8 weeks at that date, this forecast is wrong. XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. The customer notification is a single-source, circulating report: Murata's own announcement has not been independently verified, the count of affected part numbers is not disclosed, and the TrendForce figures are secondary market data.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
