For an MRO line-down or a panel builder with a closed BOM, an EOL-hot servo is still serviceable: the existing mechanical footprint, encoder interface, and connector pinout remain valid against any drive already configured for this code — what changes is the procurement channel, not the field replacement.","metaTitle":"Siemens 1FK7042-5AK71-1UA0 Servo Motor, EOL phase-out","metaDescription":"1FK7042-5AK71-1UA0 — Siemens SIMOTICS S servo motor, 2.22 kg, listed as EOL hot.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-5AK71-1UA0","Part #":"1FK7042-5AK71-1UA0","Weight":"2.22 kgs","Category":"Motors","description":"1FK7042-5AK71-1UA0 - SERVO MOTOR by SIEMENS","Sub Category":"Servo Motors","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2,835.78","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Will 1FK7042-5AK71-1UA0 drop into a panel that was specified around 1FK7042-5AK71-1KG3 without rewiring?","answer":"The two codes share the same 2.22 kg figure and the same SIMOTICS S-class stem, which positions them as a like-for-like swap inside the family — the mechanical footprint and the motor-half interface match closely enough that a panel rebuild does not require a drive reconfiguration, though the connector and encoder suffix should still be confirmed against the original BOM before committing."},{"question":"Where can I buy 1FK7042-5AK71-1UA0?","answer":"It is sourced to order through independent distribution against an RFQ — pricing and current availability are confirmed at quote time, with each line traceable through the supplier chain."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-5AK71-1UA0","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/1FK7042-5AK71-1UA0 when reusing this data.
