Product details

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.

Frequently asked questions

Can the 1FK7042-5AK71-1UA2 be replaced by the 1FK7042-5AK71-1KG3 without rewiring?

Same frame, same 2.22 kgs — the mechanical envelope lines up. But the suffix difference (-1UA2 vs -1KG3) typically encodes winding and feedback options in this family, so electrical drop-in depends on the specific drive commissioning parameters. Match the winding code and encoder type against the original axis configuration before swapping; if those match, the panel-side wiring and connector pinout carry over.
