Discontinuations taken from Molex's own Product Change Notification PCN 515981 (Molex, LLC, Date Issued 1 October 2024; Reason for Change: Obsolete) — the 722-part Molex mega-notice that was opened in full at the Molex v1 build (two printings, TTI and DigiKey, agreeing exactly) and deliberately held as this v2 slice. Every record is one part number from the notice's governing PCN No / Part List, in printed order, with the notice's dates.
No replacement is printed for any part: the notice's Description of Change states "Obsolescence without Replacement" for the whole notice. Every record's replacement field reads "None named" — no successor is inferred anywhere.
Time status: last time buy was 25 June 2025, last time ship 25 September 2025 and planned implementation 31 October 2025 — all passed. This file is the definitive Molex-published discontinuation list for these parts, not a buy window.
Counting basis, stated plainly: PCN 515981's governing Part List prints 722 unique part numbers. Seventy-nine of them also appear in the Molex v1 dataset under PCN 515990 (issued the same day), where each carries a printed replacement — those 79 are not repeated here, so this file carries 643 records and shares no part number with v1 (asserted programmatically at build). The v1 research file put that overlap at 20 parts; this build's first-hand, part-by-part comparison against the shipped v1 file counts 79, and the first-hand count governs — the correction is documented in the paid file and the research notes.
Honesty notes: Molex has issued partial retractions of obsolescence PCNs (PCN 517229 / 517609); the 517609 copy names neither the retracted PCN nor any part, so no reconciliation against PCN 515981 is possible from the hosted copies — disclosed in the paid file, and PCN 515981's opened copy carries no retraction marker. Two further Molex mega-notices remain unshipped: PCN 514995 (978 parts; its only located copy is a bot-walled TTI printing) and PCN 517169 (aggregator copy only).
Verification standard: Molex-authored PCN only — downloaded first-hand by the build run from DigiKey's media server (a mirror of the identical Molex PDF) and parsed programmatically from the PDF's text layer (722 tokens, 722 unique), cross-validated token-for-token, in set and order, against the v1 research pass's independent transcription of the same notice and draft B's machine count of the TTI printing (722).
