Lifecycle read: eol_hot and what it means at the RFQ
The 1FK7011-5AK74-1AH3: For a buyer this shifts the sourcing model: there is no fresh-factory quote, so the procurement question becomes how many pieces a broker or surplus channel can deliver, what trace documentation travels with each unit, and whether the cable and connector code on the motor matches the drive commissioning the cell was designed around. Quote-to-order against an RFQ is the realistic path; availability, condition, and any trace paperwork are confirmed at quote time.

Pin-compatible alternatives within the 1FK7 frame exist for different winding/inertia options, but the only official replacement recorded for this exact order code is what Siemens published in the 1FK7 migration notes — confirm the successor code against your drive firmware version and the encoder type before committing to a swap, because the encoder protocol and shaft keying drive the mechanical fit.
