What this motor is on the shelf
The 1FK7042-5AK71-1GG5 is a Siemens 1FK7 compact synchronous servo motor, the kind of brushless servo that drops onto a SINAMICS drive through a resolver or encoder cable and bolts into a machine frame for high-dynamic positioning duty.
Lifecycle read — eol_hot and what that means for the BOM
The order code is flagged eol_hot in the manufacturer record, which is the Siemens phase-out state between last-time-buy and the door closing on new-build — production is winding down and remaining stock is what the channel has. For a procurement line that is mid-life on a machine, that flag drives the BOM decision: do not re-spec this MPN into a new build; for a running line with spares, treat it as a last-time-buy target and quote against whatever independent-channel inventory the franchised distributors and brokers are still holding.
Sourcing posture — quoted to order, not off the shelf
With a motor in the eol_hot state, supply is not a stocked SKU pulled from a factory bin — it is traced through independent distribution against an RFQ, with lot size and price-break confirmed at quote time because the remaining new-build units move in lotted batches rather than continuous runs.
