Hot EOL on the 1FK7 — what changes for the BOM
The 1FK7043-4CF21-1RG0 carries a of eol_hot on the catalog record, so the standard new-unit channel is closed or winding down and any remaining stock moves through surplus and broker inventory rather than factory replenishment. For a category strategy view, an eol_hot flag on a Siemens 1FK7 synchronous servo concentrates spend under management onto a shrinking supplier pool — the lever now is allocation of known-good surplus against the install base, not volume re-buys at the OEM price book.
Mechanical envelope and panel-side handling
Servo motors in this class are paired with a SINAMICS drive on the same DC-bus family; the encoder feedback, holding brake option and shaft keying live inside the 1FK7 order code, so a replacement motor must match the original suffix string to drop onto the existing commissioning map without re-parameterising the drive.
