The fifteenth Diodes Incorporated slice: 232 discontinued device part numbers from two further Diodes-authored Product Change Notices that no earlier Diodes dataset ships — the first two of the further index notices named at the v14 build, downloaded from diodes.com: PCN-2539 REV 1 (notification 9 September 2021; implementation 9 March 2022; Analog; 213 records shipped of 217 printed) and PCN-2688 REV 1 (notification 31 May 2024; implementation 27 November 2024; Discrete Semiconductor — automotive products; 19 records). 23 records carry a printed per-part recommended replacement; the other 209 print none. Zero overlap with the Diodes v1–v14 datasets (asserted at build).
What is in the file: PCN-2539 = Table 1: 5 pairs (PI3HDX / PI3USB interface parts and PI6C10810HE → their -EX forms; life-time buy), Table 2: 17 pairs shipped of 19 printed (AP1609 / AP1661 / AP1662 / AP1694 / AP3019 regulators and drivers, AZV331 comparators, GP4505 / GPR34330 parts, LFV250003 → NX73V25003; no life-time buy; the two AL3022 pairs are excluded under the ships-once rule — they already ship in the v3 dataset under PCN-2519), Table 3: 86 (the F-series crystal and order-code list, PI6C / PI6LC / PI6ULS / PI7C / PI49FCT / PI90LV parts, SNK / SNL / SRX / UX / YNC codes; life-time buy, no replacement), Table 4: 105 shipped of 107 printed (AP1681–AP3970 regulators and controllers, AP2112–AP2213 LDOs, GP107–GP350 parts; no replacement, no life-time buy; AP3783BK6TR-G1 and AP4341NTR-BG1 excluded under the same ships-once rule). PCN-2688 = Table 1: 3 (DDZX26Q-7, SBR8U20SP5Q-13, SBRT05U20S3Q-7; no replacement, no life-time buy), Table 2: 15 (ZTX automotive transistor orderables; life-time buy, no replacement), Table 3: 1 pair (MURS160Q → MURS160Q-13-F).
One offset-baseline cell: PCN-2539 Table 2's replacement for AZV331KSTR-G1 (LMV331SE-7) prints about 2.2 pt below its row's baseline — the parse pairs it by per-column sequence zip (the method the v10 build used for PCN-2759's offset tables), asserted by name. A colour/strikethrough scan of both notices (the caution-class check from the PCN-2492 / PCN-2654 builds) finds no coloured or struck part token in either — both are REV 1 notices with no removal note.
Schedule, as printed: PCN-2539 Tables 1 and 3: last order 9 March 2022, final shipments 9 September 2022. PCN-2688 Table 2: last order 27 November 2024, final shipments 27 May 2025 (subject to availability, as printed). Every window in this slice has closed at compilation.
Verification standard: Diodes-authored notices only, downloaded first-hand from the OEM's own domain (no distributor mirror), parsed by printed baseline and column sequence with every pairing asserted, cross-validated against an independent pdftotext -layout extraction, and checked for zero overlap against all fourteen shipped Diodes files at build. Facts only — no notice prose reproduced beyond short operative quotations.
