Quotations on the -1FB3 run through independent distribution against the BOM line; current pricing and any available unit count come back with the quote rather than off a published list.","metaTitle":"Siemens 1FK7042-5AF71-1FB3 Servo Motor, 1FK7 Compact","metaDescription":"Siemens 1FK7042-5AF71-1FB3 1FK7 compact synchronous servo motor, 5.44 kgs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AF71-1FB3","Part #":"1FK7042-5AF71-1FB3","Weight":"5.44 kgs","Category":"Motors","description":"1FK7042-5AF71-1FB3 - 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":"$4,267.28","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is 1FK7042-5AF71-1FB3 available via RFQ confirmation and what is the lead time?","answer":"Availability and pricing on 1FK7042-5AF71-1FB3 are confirmed at quote time through independent distribution — there is no standing shelf stock to point at, and lead time is lot-specific."},{"question":"Is 1FK7042-5AF71-1DB0 a drop-in replacement for 1FK7042-5AF71-1FB3?","answer":"The 1FK7042-5AF71-1DB0 sibling shares the same 5.44 kgs and 1FK7 compact frame as the -1FB3, which is the first variant a buyer cross-checks against an installed machine specified around the -1DB0 order code.
