Siemens 1FK7 compact synchronous servo motor, 1FK7042-5AK71-1KG0, 4.54 kg, lifecycle stage EOL.
| Parameter | Value |

| Weight | 4.54 kgs |
The 1FK7042-5AK71-1KG0 from Siemens sits in the 1FK7 compact synchronous motor family and is listed with lifecycle stage EOL, which means the OEM channel is closed and the only honest path is independent surplus and broker sourcing quoted to order against the BOM position.
The two share the same 4.54 kg mass and live in the same 1FK7 compact family, so the mechanical bracket and coupling envelope match. Whether the wiring, encoder feedback, and SINAMICS drive parameter set are drop-in compatible is a separate engineering check against the variant codes — the weight match alone does not guarantee a wiring-for-wiring swap.
Quoted to order through independent distribution: a buyer submits the MPN and quantity, lot pedigree and traceability documentation are confirmed at quote time, and pricing is set against the available surplus market rather than a live OEM price list.
