Is this Siemens 1FK7 still in active production?
The 1FK7040-5AK71-1FH3 sits in the EOL-hot bucket on the record, which means the factory channel is closed and the part now moves through independent surplus and broker stock rather than new factory shipments. No official Siemens second-source or pin-compatible successor is on file for this exact order code, so any replacement on a downed machine has to be verified against the existing drive parameter set and shaft mounting before it goes in the panel.
What a tech needs to know before pulling the trigger
Before the swap, confirm the encoder variant and brake option from the nameplate against the original BOM line; the 1FK7 family shares a frame but splits on feedback type and holding brake, and getting that wrong is the most common field-rejection on a replacement servo.
Sourcing posture for an EOL-hot servo
Independent distribution quotes against an RFQ for whatever lot quantity is still moving through the channel — price and lead time are confirmed at quote time, and traceable OEM stock is the line a controls buyer wants to see when the machine is already down.
