Product details

Sourcing posture on an eol_hot motor

The 1FK7042-5AK71-1DG0: For a maintenance spares planner watching lead time, that channel reality drives two parallel moves: pull a working quantity through RFQ now while stock is still moving, and qualify one of the in-frame peers as a second source so a future failure doesn't land on a dead order code.

Frequently asked questions

Will 1FK7042-5AK71-1DG0 drop into a panel that was specified around 1FK7042-5AF21-1UA0 without rewiring?

Both motors share the 1FK7042 frame and the 4.54 kg weight reading, so the mechanical envelope lines up — but the suffix string encodes connector family, encoder type, shaft detail and brake option, and those digits must be compared against the original build sheet before a like-for-like swap is committed.
