Same 1FK7 housing, same Siemens connector keying, same shaft — the mechanical envelope holds, so a replacement does not force a re-engineering pass on the cabinet side. The procurement friction sits in the supply chain, not the panel layout. ## Lifecycle read for a sourcing decision For a procurement gate, that translates to two paths: (a) match the existing code against surplus stock and accept the EOL risk on long-tail spares, or (b) plan a controlled migration to the current 1FK7 successor frame while keeping one or two units of this code in the MRO drawer to cover the changeover window. The first path is cheaper today and riskier tomorrow; the second is the opposite, and the decision belongs in the PCN/LTB watch, not the BOM freeze.","metaTitle":"Siemens 1FK7042-5AF71-1EG2 Servo Motor, 4.54 kg, EOL","metaDescription":"Siemens 1FK7042-5AF71-1EG2 1FK7 compact synchronous servo motor, 4.54 kg, lifecycle EOL/hot — sourced to order against an RFQ.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1EG2","Part #":"1FK7042-5AF71-1EG2","Weight":"4.54 kgs","Category":"Motors","description":"1FK7042-5AF71-1EG2 - 1FK7 COMPACT SYNCHRONOUS MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6,496.46","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 1FK7042-5AF71-1EG2 and how do I get a price?","answer":"The supply posture is lot-specific — what is on the market today may not be on the market next quarter — so the RFQ is the gate that locks both the unit count and the price ladder for the BOM."},{"question":"When sourcing 1FK7042-5AF71-1EG2, what's the closest functional second-source — 1FK7042-5AF71-1DB0?","answer":"1FK7042-5AF71-1DB0 sits in the same 1FK7 compact frame and shares the mechanical envelope, but at 5.44 kg versus 4.54 kg it carries a different feedback stack — the swap is mechanically clean and electrically requires a re-check of the encoder wiring and the drive parameter set, not a re-engineering of the cabinet."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AF71-1EG2","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/1FK7042-5AF71-1EG2 when reusing this data.
