For an MRO buyer, the practical read is: order a comfortable bench of spares now if the line is still running on this motor, because replenishment gets thinner — not cheaper — as the surplus pool drains. ## Sourcing posture for a discontinued Siemens servo The realistic procurement path on this code is a quoted-to-order RFQ through independent distribution: every quote carries a specific lot, a condition code, and trace paperwork, because the manufacturer channel is no longer replenishing stock.","metaTitle":"Siemens 1FK7042-5AF71-1UB0 Servo Motor, 2.55 kg","metaDescription":"Siemens 1FK7042-5AF71-1UB0 servo motor, 2.55 kg, flagged EOL/hot: sourced to order against an RFQ through independent distribution.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1UB0","Part #":"1FK7042-5AF71-1UB0","Weight":"2.55 kgs","Category":"Motors","description":"1FK7042-5AF71-1UB0 - SERVO MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,615.77","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I get 1FK7042-5AF71-1UB0 available via RFQ confirmation and what is the lead time?","answer":"Stock and lead time are not held as live figures on an EOL/hot code.
