The twenty-seventh Diodes Incorporated slice: 3553 discontinued device records shipped of 3605 printed from the single Diodes-authored Product Change Notice PCN-2549 REV 1 (notification 19 October 2021; implementation 19 April 2022; Discrete — Lite-On Semiconductor (LSC) brand), downloaded from diodes.com. At 33 pages it is the largest single Diodes notice in the catalogue. 1060 shipped records carry a printed per-part recommended replacement; Tables 1 and 2 print none, and the records say so. 52 printed part numbers already ship in diodes-eol-migration-v5 under PCN-2855 REV 1 and are excluded here under the ships-once rule (52 printed records removed); after the exclusion, zero overlap with the Diodes v1–v26 datasets (asserted at build).
What is in the file: Table 1 = 1439 shipped of 1449 printed (EOL devices with no replacement parts and no life-time buy opportunity); Table 2 = 1054 shipped of 1054 printed (no replacement parts, life-time buy opportunity); Table 3 = 514 shipped of 514 printed (replacement pairings, no life-time buy); Table 4 = 546 shipped of 588 printed pairings over 564 parts (replacement pairings with life-time buy — 24 parts carry two printed replacement pairings, two packing variants, and ship both). In Tables 3–4 a single printed replacement cell often serves a group of LSC packing-variant orderables; each variant ships as its own record carrying the group's printed replacement, exactly as the merged cell prints it.
Schedule, as printed: life-time buy on Tables 2 and 4 — last order 19 April 2022, last ship 19 October 2022; both dates have passed. Tables 1 and 3 offer no life-time buy.
Verification standard: Diodes-authored notice only, downloaded first-hand from the OEM's own domain (no distributor mirror). The pair tables do not print on a shared row grid, so they were parsed by printed cell geometry (each column's cell intervals from its own horizontal rules; replacement tokens assigned by glyph-centre home cell, boundary sharing and merged-cell containment — every step asserted, with replacement / packing / MPQ counts required to agree on every page), cross-validated against an independent pdftotext -layout extraction, and checked for zero overlap against all twenty-six shipped Diodes files at build. Facts only — no notice prose reproduced beyond short operative quotations.
