What the EOL/HOT flag means for the RFQ
The 1FK7064-7AF71-1KA0: An eol_hot stage is the planning cue a procurement reader watches for: the manufacturer has formally signalled retirement, distributor inventory is increasingly lot-driven, and the safest sourcing path is independent distribution with full traceability confirmed at quote time. The BOM line either freezes on this order code — with the buyer's last-time-buy quantity pinned to the installed base's MTBF window — or a board revision accepts a different 1FK7-frame member. Peer references on the same Siemens line include the 1FK7060-5AF71-1UA0, 1FK7044-7AF71-1KB0, and 1FK7042-5AF71-1DB0 — each is a separate 1FK7-frame servo with its own winding and feedback option encoded in the suffix; the part number string is the only safe differentiator because frame size, brake fitment, and encoder type all vary across that group.
