For a buyer landing on this order code with a BOM line to fill, the practical path is to quote against an RFQ against independent stock — factory-direct is unlikely to be a sustainable channel once the EOL/hot window closes, and lead-time at the OEM gets less predictable the closer the cut-off date moves.","metaTitle":"Siemens 1FK7042-5AK71-1KG3 Servo Motor, 2.22 kg, EOL","metaDescription":"1FK7042-5AK71-1KG3 Siemens servo motor, 2.22 kg, lifecycle EOL/hot — sourced to order against an RFQ through independent distribution channels.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AK71-1KG3","Part #":"1FK7042-5AK71-1KG3","Weight":"2.22 kgs","Category":"Motors","description":"1FK7042-5AK71-1KG3 - SERVO MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,714.50","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What's the closest functional second-source to 1FK7042-5AK71-1KG3 inside the Siemens line — is it 1FK7042-5AF21-1UA0?","answer":"The 1FK7042-5AF21-1UA0 sits in the same 1FK7042 frame family but at 4.54 kg, which signals a higher-inertia rotor variant; it is a functional sibling on the same SIMOTICS platform, not a true drop-in — the drive commissioning parameters (current / speed loop gains, torque limits) need to be re-set against the new motor data record because the rotor inertia and torque constant differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AK71-1KG3","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/1FK7042-5AK71-1KG3 when reusing this data.
