Product details

EOL hot and what it does to the BOM line

The 1FK7042-5AK71-1FA0: EOL hot on a Siemens servo motor is the run-down phase: the factory is winding down production and allocations are tightening while stock is still being drawn — a new design should pick a current-production 1FK7 successor, but a maintenance spare or a one-for-one swap on an existing machine can still be sourced through independent channels, with availability and pricing confirmed at quote time.

Frequently asked questions

When sourcing 1FK7042-5AK71-1FA0, what's the closest functional second-source — 1FK7042-5AF21-1UA0?

The closest weight-matched peer in the same 1FK7042 frame is 1FK7042-5AF21-1UA0 at 4.54 kgs — it is the same compact synchronous motor body and mechanically interchangeable on the panel, but the winding and feedback options differ between sub-variants, so the drive parameter set has to be re-entered against the new motor ID at commissioning rather than treated as a true second source.
