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.","metaTitle":"Siemens 1FK7042-5AK71-1UA2 Servo Motor, 2.22 kgs","metaDescription":"Siemens 1FK7042-5AK71-1UA2 SIMOTICS S-1FK7 servo motor, 2.22 kgs, lifecycle stage eol_hot.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AK71-1UA2","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/1FK7042-5AK71-1UA2 when reusing this data.
