Identity and shaft-side fit on a 1FK7 frame
The 1FK7042-5AF71-1EG2: For a retrofit integrator, the practical question is whether this code can meet it where it is — meaning a drop-in for a machine originally wired around the same frame. Same 1FK7 housing, same Siemens connector keying, same shaft — the mechanical envelope holds, so a replacement does not force a re-engineering pass on the cabinet side. The procurement friction sits in the supply chain, not the panel layout.
Lifecycle read for a sourcing decision
For a procurement gate, that translates to two paths: (a) match the existing code against surplus stock and accept the EOL risk on long-tail spares, or (b) plan a controlled migration to the current 1FK7 successor frame while keeping one or two units of this code in the MRO drawer to cover the changeover window. The first path is cheaper today and riskier tomorrow; the second is the opposite, and the decision belongs in the PCN/LTB watch, not the BOM freeze.
