What this motor is and why it is on a sourcing list
The 1FK7042-5AK71-1UH2 is a Siemens 1FK7 compact synchronous servo motor in the servo-motor class, built for the high-dynamic positioning loops that Siemens Sinamics drives run as part of an integrated motion axis.
Lifecycle status and what that means for the BOM
The catalog record carries = eol_hot, so the line is no longer on Siemens' standard orderable list — the realistic channels are remaining factory stock and independent distribution, and every quote is lot-traceable against the original manufacturer paperwork.
How the part is quoted and what the buyer sees
Volume enquiries are priced per RFQ against the lot available at the time of quote; the BOM line is what drives the offer, and current availability is confirmed at quote rather than carried as standing stock.
