For a robotics integrator that means locking in the BOM quantity now: once Siemens stops taking orders, the only supply path is independent distribution carrying new-surplus or factory-traceable stock, and that path is RFQ-driven rather than live-stock. Siemens is the OEM of record — the part ships under the 1FK7042-5AF71-1KB0 designation, and any replacement should be cross-referenced through Siemens' own configurator before being treated as drop-in compatible.","metaTitle":"Siemens 1FK7042-5AF71-1KB0 Servo Motor, 2.68 kg","metaDescription":"Siemens 1FK7042-5AF71-1KB0 servo motor, 2.68 kg, EOL/hot lifecycle — quoted to order against an RFQ through independent channels.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1KB0","Part #":"1FK7042-5AF71-1KB0","Weight":"2.68 kgs","Category":"Motors","description":"1FK7042-5AF71-1KB0 - SERVO MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5,250.62","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for 1FK7042-5AF71-1KB0?","answer":"Submit an RFQ with the BOM quantity and the cell the motor is feeding — pricing and lead time come back per quote from independent stock carrying this code, with traceability documented at order time."},{"question":"What's the listed weight on this servo motor?","answer":"The spec table lists 2.68 kg for the 1FK7042-5AF71-1KB0, which is what the cell-side bracket and counterbalance calc should use."},{"question":"Will 1FK7042-5AF71-1KB0 drop into a panel specified around 1FK7042-5AF71-1DB0 without rewiring?","answer":"Not as a straight swap.
