For a panel already wired to this exact order code, a like-for-like replacement against the same MPN preserves the encoder resolution, brake option, and shaft geometry that were specified into the drive configuration.","metaTitle":"Siemens 1FK7042-5AF71-1PA3 Servo Motor, EOL, 4.54 kg","metaDescription":"Siemens 1FK7042-5AF71-1PA3 1FK7 compact synchronous servo motor, 4.54 kg, lifecycle stage eol_hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1PA3","Part #":"1FK7042-5AF71-1PA3","Weight":"4.54 kgs","Category":"Motors","description":"1FK7042-5AF71-1PA3 - 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":"$2,369.10","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will 1FK7042-5AF71-1PA3 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?","answer":"Not on weight alone — the -1DB0 sibling is listed at 5.44 kg against the -1PA3's 4.54 kg, a 0.90 kg delta that signals a different rotor stack, brake, or encoder option inside the same 1FK7042-5AF71 base.
