EOL/HOT on record — the sourcing read
The 1FK7042-5AF71-1EB3 carries an eol_hot lifecycle stage in the catalog record, which means Siemens has stopped taking new orders for the standard production run and the only channels moving this code are surplus stock, brokers, and repair-exchange inventory tied to the 1FK7 frame. 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.
