That is the single most important fact on the page: production is no longer the answer for a BOM line carrying 1FK7042-5AK71-1FH3 — independent surplus, lot-traced and date-coded, is.
For a capex project that still has this code on a drawing, the question is not whether to redesign the axis around it but whether the quantity required can be sourced against the spare-parts and startup-spares package in one RFQ.
Not on the suffix evidence alone — both motors share the 5.44 kgs 1FK7042 frame, but the trailing suffix encodes encoder, holding brake, shaft and connector choice, and that is what decides mechanical and electrical fit. Confirm the full suffix against the nameplate of the installed unit before committing.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
