Lifecycle stage and what it means for the BOM line
The 1FK7042-5AK71-1FG3: The ledger carries eol_hot on this code, which puts the part in the active tail of the Siemens 1FK7 production run — units are still moving out of Siemens but the line is winding down, so new-build allocations go through tighter stock control than a fully current frame. For a procurement line this reads as: commit early, do not assume a fresh allocation at the back end of a long build cycle.
