Discontinuation taken from Littelfuse's own obsolescence / discontinuation notices — Littelfuse-authored PDFs opened in full as distributor-hosted mirrors of the identical notices (TTI / TTI Europe, Mouser, DigiKey; LFPCN 41521-1 via a manuals.plus mirror), because Littelfuse hosts no public PCN library on littelfuse.com. Every record is one row (or, for the ADC notice, one unique entry) of a notice's affected-parts list, across 10 notices: ADC_20250623_002 (238 unique records — fuse holders & specialty fuses, immediate EOL, first grid only), PCN C0586 (86 records — DC contactors, every one with a named alternative and a 14 July 2025 last time buy), LFPCN 41521-1 (49 records — blue-coating axial AK-series TVS parts; replacements withheld as unpairable, see below), EDC_20250731_006 (29 records — magnetic sensors, immediate EOL, legible rows only), LFPCN 41386 (7 records — 55100-AP/55140-AP Hall sensor variants), PCN EIC-1099 (6 records — IXYS ICD PLA192E/PLA193E solid-state relays, all with named replacements), LFPCN-C0510 (4 records — direct replacements), PCN EIC-1113 (3 records — PLA134 family, LCA701 named at family level), and the single-record LCFE160804A350TG and LFPCN.C0522 notices — the exact Littelfuse part number, the replacement exactly as the notice prints it where one is printed per part, and the notice's issue, last-time-buy and last-ship dates. 96 of the 424 records name a per-part replacement or alternative.
Time-critical: LFPCN 41521-1's last shipment is 30 December 2026 — the AK-series blue-coating TVS set (its last time buy, 31 March 2026, has passed). Its replacements are the same part numbers in an improved yellow coating, available via Littelfuse sales.
Counting basis, stated plainly: one record per affected-parts row at the exact orderable part number as printed (238 + 86 + 49 + 29 + 7 + 6 + 4 + 3 + 1 + 1 = 424); the ADC grid's 240 printed entries carry one repeated pair, counted once.
Honesty notes: LFPCN 41521-1's replacement column flattens into a detached block in the PDF text layer and position-counting pairs it off-by-one, so its per-part replacements are withheld rather than guessed — the obsolete list itself is clean. Four magnetic-sensor part numbers garble in their notice's text layer and are excluded, not reconstructed. The ADC notice's second grid (~320 entries) fragments in the text layer and is not shipped. PCN C0586 rows 87–89 print no obsolete part and are excluded. C&K-branded PDNs found in research (38 records) are excluded — C&K is a Littelfuse-owned brand, but those documents carry C&K letterhead only. The CVP mega-notices C0557 and V0525 are held as future slices.
Verification standard: Littelfuse-authored notices only — the 10 notices above, each opened in full as the identical notice's distributor mirror, with the build run's first-hand reads agreeing with the parallel research pass.
