All 102 numbered product rows from two Hirose Electric-authored Product Change Notifications, each opened in full as the OEM's own PDF via a distributor mirror — PCN2025-09 (2025; compliance with the POPs Convention: material change and sales discontinuation; 48 records) and PCN2021-11 (2021; TSCA material change of non-compliant product and discontinued sales; 54 records). Hirose prints material-change and discontinued-sales rows in a single Attachment 1 list under a single schedule; this file preserves that structure and separates the two classes record by record in its Change Type column.
60 records carry a printed replacement (PCN2025-09: 30 HR34B rows, each to its printed (40)/(43) substitute; PCN2021-11: 30 rows, each to its printed (16)/(15)/(17) TSCA-compliant replacement); 42 records are discontinued sales with no replacement planned (PCN2025-09: 18 — HR08D, the D-sub dust caps, DX caps and MF13/MF25 parts; PCN2021-11: 24 — RF/coax UG/BNC/TNC parts, tooling, FX2C, HRFC, HSC and one MF13 cable assembly).
Cross-notice chain, stated plainly: PCN2021-11 changed the D-sub dust caps and several DX/MF parts to their "(16)" TSCA-compliant forms — and PCN2025-09 then discontinued those same "(16)" forms outright under the POPs Convention. Both steps ship as separate records; every record's current part number is a distinct orderable (all 102 unique, asserted at build).
Schedules as printed: PCN2025-09 — final order reception 31 March 2026, final shipment 31 August 2026 (both passed), substitutes first received 1 September 2025. PCN2021-11 — final order reception 30 September 2021, final shipment 31 October 2021 (both closed). This file ships as a verified discontinuation / migration cross-reference.
Verification standard: Hirose-authored notices only, downloaded first-hand by this build run (PCN2025-09 from DigiKey's media server; PCN2021-11 from a mirror of the Hirose Electric USA document) and parsed by printed span coordinates — rows anchored on the printed row number, pairings asserted row by row — cross-validated against independent pdftotext extractions. One record (PCN2021-11 row 17, a Japanese-named CTB tooling item) ships exactly as the PDF text layer prints it, flagged in the file.
