Product details

What an EOL-hot servo motor means for the BOM line

The 1FK7042-5AF71-1EG0: Because the original Siemens production run has closed, nameplate vs PO trace becomes the load-bearing QC step — the declaration pack that accompanies the motor has to reconcile the serial number on the motor face with the lot on the invoice before it goes into a build that is destined for an end-client audit, and any compliance doc the customer asks for (RoHS, REACH, UL, IEC) needs to be sourced from the independent channel at the same time as the hardware.

Sourcing posture for an obsolete compact servo

Quoted to order against the BOM from independent distribution: no stock count, no ship date, and no price quoted on this page — those answers are returned against an RFQ after the channel confirms whether the lot is traceable surplus, factory-overrun, or broker stock, because the eol_hot stage means the same order code can land any of those three ways depending on which independent line carries it.

Frequently asked questions

Who supplies 1FK7042-5AF71-1EG0 and how is it quoted for volume purchases?

The motor is quoted to order through independent distribution against an RFQ — availability, lot traceability, and volume pricing are all confirmed at quote time, not pre-stated on a listing.

Will 1FK7042-5AF71-1EG0 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?

It cannot be assumed drop-in compatible: the recorded mass of this motor is 2.04 kg versus 5.44 kg on the 1FK7042-5AF71-1DB0 sibling, which is a large enough delta to invalidate the original shaft-load and coupling-alignment calculations, so the mechanical side of the panel needs re-checking before any approved-alternate tick on the customer's AVL.
