What an EOL servo motor changes on the BOM
The 1FK7042-5AF71-1GG5: An eol_hot flag on a 1FK7 compact motor means a new-equipment design should already be planning the migration path to the current 1FK7 successor shaft height or the SIMOTICS S-1FK2 family — the part will still physically bolt in and talk to a SINAMICS S120 drive over DRIVE-CLiQ the same way it always did, but the warranty clock and the firmware compatibility matrix are not the same as a motor you could reorder next quarter. Spares buyers are usually the ones still chasing this code, not new-machine OEMs. For a small shop running a machine where this motor already lives, the realistic move is to pull a spare now while traceable stock is still moving through independent channels, and to keep the encoder parameters and resolver / absolute-value configuration noted on the panel drawing — that's the data that bites you if you ever have to swap to a successor and the drive throws an encoder topology fault on first commissioning.
