Lead time depends on the specific lot on offer and is part of the quote response.
No — the 7043 frame is a 63 mm shaft-height unit at 6.80 kg, while the 1FK7042-5AF71-1DB0 is the 48 mm shaft-height '7042' frame at 5.44 kg; flange bolt pattern, stack length, and encoder option differ between the two frames, so a mechanical and electrical review is required before any swap.
