Product details

What the EOL flag means for a sourcing decision

The 1FK7042-5AF71-1PA3: An eol_hot lifecycle stage is the signal to lock the BOM position: the manufacturer will not build new units beyond the last buy date, and any future replacement comes through independent distribution, surplus, or a remanufactured exchange. For a panel already wired to this exact order code, a like-for-like replacement against the same MPN preserves the encoder resolution, brake option, and shaft geometry that were specified into the drive configuration.

Frequently asked questions

Will 1FK7042-5AF71-1PA3 drop into a panel that was specified around 1FK7042-5AF71-1DB0 without rewiring?

Not on weight alone — the -1DB0 sibling is listed at 5.44 kg against the -1PA3's 4.54 kg, a 0.90 kg delta that signals a different rotor stack, brake, or encoder option inside the same 1FK7042-5AF71 base. Flange, shaft, and connector keying are shared on the base code, so the mechanical footprint matches, but the drive configuration file must be re-validated against the new encoder and brake selection before commissioning.
