What this code is and where it sits
The part is a Siemens 1FK7 compact synchronous servo motor, ordered under code 1FK7015-5AK74-1JA3 — the 1FK7 family is the small-frame brushless servo line that drops onto a SINAMICS drive through the standard electronic nameplate hand-off, used in feeders, indexing tables and small-format packaging axes where the cabinet real estate matters more than torque headroom.
Lifecycle is the headline here
Lifecycle is flagged EOL/hot — meaning the factory has cut new production and the only clean supply runs through the surplus and independent-distribution channel, not the standard Siemens factory-order line. That makes the BOM decision a sourcing question first, a fit question second: confirm motor frame, shaft, brake option and resolver/encoder code against the nameplate of the unit being swapped before committing, because a wrong match on this family is a spindle-out rebuild.
