What the eol_hot flag means for the BOM line
The 1FK7022-5AK21-1PA3: An eol_hot reading on a 1FK7 compact motor usually means the order code is still orderable for a defined window or has transitioned to surplus-only — either way the procurement decision is no longer 'place a PO against stock' but 'confirm availability and price against an RFQ'. For a line-down spare, second-source planning is the sharper move: survey the cross-reference to the current 1FK7 successor in the SIMOTICS S family before locking the BOM, because the mechanical shaft and connector interface can shift between Compact generations even when the torque frame looks the same.
