Cat-4 short, EOL-hot – what arrives on the dock
The 1FK7063-5AH71-1KA0: 1FK7-series motors are low-inertia, high-dynamics units typically paired with SINAMICS S120 drive electronics on packaging, converting, and machine-tool axes — EOL-hot means production windows are narrowing, which is what drives the BOM-freeze decision rather than a re-engineering one.
Cat-4 panel-side considerations: 5.14 kg and shaft interface
For panel-side planning, confirm the mating connector code on the nameplate before pull-from-stock — the 1FK7 family uses both power and feedback connectors whose keying varies by encoder option, and an EOL-hot part has no tolerance for a wrong-keying return.
Cat-4 sourcing posture: EOL-hot under independent distribution
No official successor or second-source cross-reference is recorded for the 1FK7063-5AH71-1KA0 in this ledger, so the safer spec-side move for a new design is the SIMOTICS S-1FK7 compact family at the same shaft height — that is an architectural suggestion, not a confirmed drop-in.
