Product details

What this motor is on the line

The 1FK7042-5AK71-1FG0: Its listing carries = eol_hot: the variant is no longer in broad factory distribution, so procurement moves off the franchised spool and onto independent channels where lot-specific stock is matched to the BOM at RFQ.

Sourcing posture when the variant is eol_hot

Where to buy 1FK7042-5AK71-1FG0 in practice: independent distribution is the active channel — availability is lot-specific and the price ladder is confirmed against the RFQ quantity, not against a live webshop row. No factory-direct promise, no same-day ship claim.

Frequently asked questions

Will 1FK7042-5AK71-1FG0 drop into a panel that was specified around 1FK7042-5AF21-1UA0 without rewiring?

Not directly — 1FK7042-5AK71-1FG0 is 2.05 kg while the listed sibling 1FK7042-5AF21-1UA0 is 4.54 kg, so the shaft, flange and stator length differ; the encoder and brake options are coded into the order-code suffix and need to be matched against the original BOM line, not assumed from the frame class alone.
