What the EOL-hot flag means for this 1FK7 motor
Siemens 1FK70425AF711PG3ZN05 is a compact synchronous servomotor in the SIMOTICS S-1FK7 family, and the lifecycle record on file carries an EOL-hot stage — meaning the factory has formally moved it out of standard production but support, repair, and limited supply continue for a defined window. Servomotors in this class are paired with a SINAMICS drive on a closed-loop position / speed bus, so the spindle-side encoder feedback and the winding code are what actually determine whether a candidate unit is drop-in for a given machine — not just the frame size.
What the BOM row needs vs. what the record carries
For a value-engineering buyer, the practical read is straightforward: an EOL-hot servomotor is no longer a quoted-to-order active SKU, but it is also not yet scrap — the supply posture shifts from authorized distribution into independent / broker channels where each line is lot-specific and priced to the BOM.
Sourcing posture for a discontinued servomotor
Because the lifecycle field reads EOL-hot, any RFQ against 1FK70425AF711PG3ZN05 is treated as a legacy / last-time-buy request — the part is sourced through independent distribution rather than the factory-direct channel, lot availability and warranty terms are confirmed at quote time, and no second-source cross-reference is on file from Siemens for this exact order code.
