1FK7042-2AF71-1EA0 — what the order code places on the BOM
The 1FK7042-2AF71-1EA0 sits in the Siemens 1FK7 compact synchronous servo motor family, used on machine axes where a small-frame permanent-magnet synchronous drive pairs with a SINAMICS drive line for positioning and speed loops.
Lifecycle stage and category-strategy read
Lifecycle stage is flagged EOL on this code, meaning the original Siemens production window has closed and the supply path moves from authorized catalog distribution into the independent channel — spot stock, factory surplus, and broker lots, each with its own traceability profile. From a category-strategy angle, an EOL on a Siemens 1FK7 compact is the kind of obsolescence event that forces the spare-parts leg of the BOM off the preferred-supplier track and onto a de-risked supply base; the strategic move is to confirm the installed-base quantity, lock a final buy if the line is still supported by a successor family, and qualify a second source before inventory burns down.
