Yageo Group (KEMET / YAGEO / Pulse) Electronic Component EOL & Migration Reference

Discontinuation taken from the Yageo Group's own PCN / Product Termination Notification (QOD-510) / EOL notices — group-authored PDFs opened in full as authorised-distributor mirrors (TTI, TTI Europe, DigiKey, Mouser, AllElco); none of KEMET, YAGEO or Pulse Electronics hosts a public notice library of its own. Every record is one entry of a notice's own governing part list, across 16 notices from the group's three component brands: EOL-032024-NLG (5,892 records — the KEMET C900 Safety Disc discontinuation's system-active list, 184 parts carrying their printed C700 alternative), PTN-250417-KB (4,476 records — the Mylar Specialty Film Luxembourg Line 5 shutdown's own 'KPN Combined' annex list), PTN-241120-KB (1,073 records — filter product series, recovered from the annexes' KEMET↔vendor part-number pairings), PTN-230331-KB (969 records — AC product series A70 / A72 / C24 / C3B / C44 / C4B / C4H / C4M / C95 / JSP), EOL-051525-AGA (471 records — commercial SMD X5R & Y5V MLCC raw-material obsolescence, exact system list, not the notice's wildcard patterns), PCN-011626-KB (101 records — PHE850 10 mm-pitch film phase-out, 64 with printed R41 alternatives), XSemi-002 (54 records — YAGEO XP-series semiconductors), PCN-100000820 (62 records — Pulse magnetics and SFP/QSFP cage assemblies, 5 with printed replacements), EBR-0176-2025110502 (25 records — YAGEO TSS products), PCN-281025-TXD (10 records — KEMET MPLC power inductors, every part with its printed MPX1D successor), PCN-261018-UMQ (9 records — T428 tantalum H-termination, every part with its P-termination successor), PCN-100000787 (4 records — Pulse LAN magnetics), EBR-0176-2025051501 (3 records — YAGEO ESD products), EBR-0176-2025110501 (33 records — YAGEO ESD products, November 2025 notice), PCN-041526-KG (2 records — KEMET C44 forced phase-out) and ARM_04122023 (2 pattern records — Pulse ARM series, patterns exactly as printed) — the exact part number, the replacement exactly as the notice prints it where one is printed per part, and the notice's issue / last-time-buy / last-ship dates. 275 of the 13,186 records carry a printed per-part replacement.

Time-critical, stated plainly: the MPLC inductor notice (PCN-281025-TXD) has the file's only still-open window — end-of-life / final delivery is 31 October 2026 (last time buy closed 30 April 2026), and every part names its MPX1D successor. The Pulse PCN-100000787 last shipment runs to 22 December 2026. Every other notice's window has closed, and for those the value is the verified discontinuation and replacement record itself.

Counting basis, stated plainly: one record per unique part number in a notice's own governing part list (5,892 + 4,476 + 1,073 + 969 + 471 + 101 + 54 + 62 + 25 + 10 + 9 + 4 + 3 + 33 + 2 + 2 = 13,186). Where a notice carries both a customer / sales list and a master or catalogue list, the master list governs: PTN-250417-KB's Annex 1 distributor rows (backlog / invoiced / shipped, with sales data) and its February 2025 advance letter for the same Mylar event ship nothing, and PCN-011626-KB's Annex 1 customer list ships nothing. The C900 alternative table (headed '24 months sales history') supplies only the replacement column — the record set is the notice's system-active list plus the 2 alternative-table parts absent from it.

Honesty notes: PTN-241120-KB's annexes print the KEMET and vendor columns in both orders; records were recovered from the pairings (vendor = KEMET number with an F or A prefix), and 41 legacy cross-reference rows whose KEMET-side number cannot be certified from the notice (39 S→DS rows, one SS cross-reference, one same-token row) are excluded, never guessed. The XSemi-002 'Recommended' column is not legibly paired in the hosted copy, so no replacement is recorded for its 54 parts. 282 of the Mylar KPNs print at 13 characters and are reproduced as printed. The November 2025 YAGEO ESD notice (EBR-0176-2025110501, 33 devices) defeated the text fetcher repeatedly; its list was read in full in a live browser session and the downloaded PDF was then parsed by the build run — the two reads are identical, and nothing was ever transcribed from a search index. Two KEMET notices carry 'Business Confidential' markings; extraction from them is facts-only (part numbers, alternatives, dates) — see the paid file's honesty notes.

Verification standard: Yageo Group-authored notices only — the 16 notices above, each opened in full; every list parsed by script with asserted counts (the KPN Combined list at 4,476 unique with zero duplicates, the C900 system list at 5,890, the AC list at 969 of 970 printed rows), the C900 alternative pairings recovered by PDF row position, the PHE850 Annex 2 pairing confirmed identical against an independent transcription, and the Mouser-hosted notices read in full in the browser.
