No official successor is carried in the record, so a board-or-mechanical-spin replacement would have to be confirmed against the current 1FK7 datasheet before committing a redesign. ## Sourcing posture for a discontinued servo Buyers chasing a like-for-like replacement should treat this as a stock-out replacement decision: either secure the 1FK7042-2AK71-1EG1 through surplus while compatible drives remain in service, or commit to a current-production 1FK7 variant after checking the shaft, brake and encoder code against the existing axis.","metaTitle":"Siemens 1FK7042-2AK71-1EG1 Servo Motor, EOL, 4.54 kg","metaDescription":"Siemens 1FK7042-2AK71-1EG1 1FK7 compact synchronous servo motor, listed at 4.54 kg, flagged EOL.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Servo Motors"],"specifications":{"title":"1FK7042-2AK71-1EG1","Part #":"1FK7042-2AK71-1EG1","Weight":"4.54 kgs","Category":"Motors","description":"1FK7042-2AK71-1EG1 - 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":"$2,986.51","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/647530720402e9bdb23d5fbad456dc20.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I order 1FK7042-2AK71-1EG1 and check current availability?","answer":"No stock count, lead-time figure, or immediacy promise is carried on the listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/1FK7042-2AK71-1EG1","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/1FK7042-2AK71-1EG1 when reusing this data.
