Siemens 1FK7042-5AF71-1AH0 — what the catalog shows
It is the motor half of a Siemens SINAMICS-class drive pair — the encoder, brake option and shaft detail live in the suffix coding, not the catalog line, so confirming the BOM against the nameplate matters before committing a replacement order (cites:,).
Lifecycle status — what eol_hot means for the BOM
The catalog carries the as eol_hot, which is the manufacturer-tagged late-availability window for this Simotics S-1FK7 frame (cites:). A line that was specified around this motor needs a like-for-like spare on the shelf now, because new-build stock of the same suffix codes tightens once the hot phase ends — independent distribution is the channel that covers the gap between official last-time-buy and field replacement demand (cites:,).
