Product details

End-of-life motor, still on the BOM

The 1FK7042-5AF71-1AH3: Lifecycle is flagged eol_hot on the record, which means the part is past its primary manufacturing window and is now sourced through independent channels rather than the factory-direct line; availability is lot-specific and confirmed only when an RFQ is in hand.

Sourcing posture for an EOL-hot servo

For a motor flagged eol_hot, the procurement question is whether the line-down spare can be secured before the surplus pool thins — the answer is quoted per RFQ against whatever quantity the buyer needs, with no standing inventory claim on this storefront.

Frequently asked questions

Will 1FK7042-5AF71-1AH3 drop into a panel that was specified around 1FK7042-5AF21-1UA0 without rewiring?

Not as a direct swap. Both share the 1FK7042 frame, but 1FK7042-5AF21-1UA0 is listed at 4.54 kg versus 2.57 kg here — the rotor mass change shifts inertia, coupling sizing and drive-side tuning parameters, so a straight panel swap will not behave the same.
