Product details

Sourcing posture for an EOL/hot servo motor

The 1FK7042-5AK71-1TA2: With the part flagged eol_hot (cites:) and no official successor on the ledger, the realistic channel is independent distribution quoting against an RFQ — lead time, lot size, and current price confirmed at quote time, not pulled from a live catalog row. Same-day shipment is not the right expectation for an EOL servo motor in this state; what the line needs is a confirmed traceable lot and a clear answer on whether the drive firmware will accept the encoder option block still soldered to the nameplate.

Frequently asked questions

Will 1FK7042-5AK71-1TA2 drop into a panel specified around 1FK7042-5AF21-1UA0 without rewiring?

The frame mass matches at 4.54 kg on both codes (cites:), so the mechanical envelope is the same; the encoder, brake and connector option block still have to be read off each nameplate and matched to the SINAMICS drive parameter set before a swap is committed — a like-for-like option code makes it a clean drop, a mismatched suffix means a parameter retune at minimum.
