Lifecycle status and the BOM-line decision
The 1FK7042-5AK71-1UA2: The catalog flag for this code is eol_hot — Siemens has moved the variant out of standard production and onto a constrained supply track. For a buyer carrying an open BOM line that points at this exact order code, the practical sourcing path is the independent distribution channel: the part is not off the market, but the unit economics shift — pricing and availability are confirmed at RFQ rather than off a published distributor shelf.
