Discontinuation taken from Littelfuse's own PCN V0525 — the Commercial Vehicle Products "Low sales obsolescence" notice of 26 May 2025, held back as a v2 slice when the Littelfuse EOL & Migration Dataset v1 was built. Littelfuse obsoleted the listed options on the V Series switch product lines (Combi Contacts, Contura VII); the notice's attachment is the complete affected list — 470 configured item numbers (RCV-…), each printed with its Search Text, the configuration code Littelfuse prints for that item. This dataset is explicitly a variant-level file: every record is one configured item from the notice's own list, with its Search Text reproduced exactly as printed.
Time-critical, stated plainly: the last-time-buy window closed 1 October 2025 — no window in this dataset is still open. The file's value is the verified record of exactly which configured V Series items are discontinued, with the configuration code a holder needs to request the new part number the notice promises through Littelfuse customer service.
Counting basis, stated plainly: one record per attachment row as the notice prints it (470 records; all 470 item numbers unique, asserted at build). The build extracted the attachment by printed column coordinates (PyMuPDF word positions) from the notice PDF and cross-validated it against an independent pdftotext -layout extraction: identical lists — the same 470 item numbers with the same Search Texts in the same order. A research draft that opened the notice earlier estimated ~700 entries without transcribing them; the first-hand recount governs.
Honesty notes: the notice prints no replacement for any item — it directs customers to contact their Littelfuse customer service representative to request a new part number, so every record reads None named and no cross is inferred from the Search Text codes (the notice prints no legend for them, so none is offered). One Search Text (V6N2UPP1-699XX-1XX-XHWT1) is printed for two different item numbers, RCV-37139331 and RCV-37139312 — both rows ship, as printed. No last-ship date is printed for any row. Zero overlap with the discontinued-part sets of the Littelfuse v1 and v2 datasets (checked programmatically).
Verification standard: Littelfuse-authored notice only — opened in full as the TTI-hosted mirror of the identical Littelfuse PDF (Littelfuse hosts no public notice library on its own site — the OEM-authorship basis is stated in full in the paid file).
