Discontinuation taken from Harwin plc's own obsolescence and discontinuation notifications — letters on Harwin letterhead signed by the Product Change Team, hosted on Harwin's own content CDNs and mirrored by distributors (CSE Solutions, connector24), every one opened in full. Harwin publishes no public PCN portal or EOL list; customers register on harwin.com to receive these notices. The 6 notices: obsolescence letter, 28 February 2014 (1 record — M80-7015122, obsolete since October 2013, closest alternative M80-7015142), PCN111, 12 August 2024 (1 record — M22C107133C, obsolete with immediate effect, no replacement), PCN112, 02 September 2024 (17 records — Gecko G125 pre-cabled Power contacts in the old numbering system, each obsoleted part paired with its printed longer replacement number; the parts are identical, only the number changed), obsolescence notification, 08 November 2024 (71 records — Gecko G125 FW/MW connectors in the old numbering system, each obsoleted part paired with its printed longer replacement number), P70 discontinuation, 07 January 2025 (3 records — P70-2600045R / P70-2610045R / P70-2620045R, each with a printed list of nearest alternatives) and the Product Discontinuation notification of 26 March 2026 (354 records — Harwin's full "Discontinued product:" list, no replacements printed).
Time-critical: no last-time-buy window in this file is still open — every timing Harwin prints is "Immediate" or a date that has passed. The March 2026 list is the headline: it discontinues 354 product variations, including many of the long-form G125 replacement numbers that PCN112 had created only 18 months earlier.
Counting basis, stated plainly: one record per part number printed in a notice's own discontinued list (1 + 1 + 17 + 71 + 3 + 354 = 447 records). The March 2026 list was parsed programmatically from the PDF and cross-checked against two independent transcriptions. 89 records carry a single printed per-part replacement; the 3 P70 records carry a printed alternatives list each.
Honesty notes: the 20 May 2024 discontinuation letter was opened in full and contributes 0 records — it prints no part numbers at all. The November 2024 notice was added as a same-run correction: held at first ship because its Mouser PDF could not be opened in full, it shipped once a live-browser read loaded it and the build run verified all 71 pairs first-hand from the downloaded PDF. Still held as v2 leads: the March 2014 Datamate spreadsheet and the 2013 J-Tek list. Pattern-only notices (RS ranges, M40-600xx46) and all change-only PCNs (design, visual, packaging) are excluded.
Verification standard: Harwin-authored notices only — the 6 notices above, each opened in full; the March 2026 list and the PCN112 table were also verified first-hand from the downloaded PDFs. Distributor lifecycle claims are excluded.
