The discontinued-sales records of two further Hirose Electric-authored Product Change Notifications, each opened in full as the OEM's own PDF via a distributor mirror — PCN2020-09 (2020; changes in tinned copper plated products) and PCN2025-08 (2025; discontinued sales of DG and DH switch). 33 records in all, every one a discontinued sale with no printed per-part replacement, and none of them in the v1 dataset (zero overlap, asserted at build).
PCN2020-09 — the discontinued tail (21 records). Its Attachment 1 runs to 687 numbered rows, but rows 1–666 are plating-specification changes, each with a named replacement — not discontinuations, and not in this file. Rows 667–687 are the end-of-sale tail, grouped in the notice under "We have no plan to sell replacement products": CTB tooling, EX80-54S-SH variants, DF30FB / DF13E / DF13EA / DF14H headers, GT8ES / GT25A / GT15J parts, MQ115 variants and WN6-00195(31). Final orders closed 31 March 2021; final shipments 31 August 2021.
PCN2025-08 — DG & DH switches (12 records). The complete Attachment 1: DG11-B1LA, five DG13 variants, DG22-B1AA, three DG23 variants and the DH2C pair DH2C-B1PA / DH2C-C4PA-C, discontinued for decreased demand. Hirose prints no substitute product of its own; its Attachment 2 names third-party equivalents at series level only (ZF DG / Omron D2FD for DG; ZF DH / Omron D2MQ for DH) — series pointers, not per-part replacements, and recorded as such. Time-critical: final orders are still being received until 31 December 2026 (final shipment 30 June 2027), though the notice warns orders may be terminated early if material supply conditions change.
Verification standard: Hirose-authored notices only, read in full in this build run (PCN2020-09 via its manuals.plus mirror copy; PCN2025-08 via Mouser's /PCN/ mirror — both hosts refuse scripted downloads, so a live full read is the extraction route) and cross-checked row-for-row against an independent scout transcription of the same two PDFs made earlier the same day: all 33 rows agree exactly, product codes included.
