What this code ships as and why the lifecycle flag matters now
The 1FK7011-5AK74-1SB3: The part is flagged eol_hot, so it is no longer in routine factory flow and the BOM line now runs on the surplus and broker channel rather than OEM scheduled production.
Where to source when the factory has stopped shipping it
With the marked eol_hot and no official successor on the record, the realistic path is independent distribution: lots and traceable surplus are quoted against the RFQ, and the original Siemens documentation remains the engineering reference for commissioning and parameter sets.
