For a buyer who needs this exact MPN — typically because a machine has a 1FK7042-5AF71-1EB3 on the bill of materials and the spare is sitting in the cabinet — the practical sourcing path is an RFQ to independent distribution, with stock quantity, traceable provenance, and date code confirmed at quote time rather than promised at search. ## What the chassis number tells you The 1FK7 prefix places this motor inside the SIMOTICS S synchronous servo family — a flange-mounted low-inertia drive used in machine-tool axis and high-dynamic positioning applications, where shaft height, feedback option, and brake configuration are decoded from the order code suffix rather than redrawn per project. ## Procurement posture for an EOL servo motor Because the 1FK7042-5AF71-1EB3 is recorded eol_hot, the buying decision shifts from catalogue pricing to lot availability — the BOM line should specify the full order code, the resolver/encoder variant, and the brake option so the RFQ returns a like-for-like match with date-code and traceable provenance.","metaTitle":"Siemens 1FK7042-5AF71-1EB3 Servo Motor, 5.44 kg, EOL","metaDescription":"Siemens 1FK7042-5AF71-1EB3 servo motor, 5.44 kg, flagged eol_hot — quoted to order through independent distribution.
