What it is and the line behind it
The Siemens 1FK7022-5AK71-1DG5-Z-J02 is a compact synchronous servo from the 1FK7 family — the short-stack rotor platform sized for high-dynamic positioning on packaging, small-format converting and feed axes.
Lifecycle read on this specific build
The listing carries eol_hot, meaning the factory has stopped taking new orders and remaining stock moves through the independent channel; the original Siemens configurator typically rejects this code as a new build at this point. The -Z-J02 suffix is an engineered variant — the build sheet on the nameplate has to match the existing axis (encoder type, brake, holding-brake voltage, connector orientation) or the replacement will not drop in mechanically or electrically.
Sourcing posture for a hot EOL code
Buyers running a single-line spare should lock the variant from the failed nameplate (encoder, brake, connector) and quote a matched quantity plus a one-up spare; matched spares are the only way to avoid a commissioning-day swap mismatch on an EOL code.
