Sourcing Reality
The ACS800-U1-0004-5+N661+P901: With an eol_hot lifecycle status, this part is not available new from ABB. Procurement should plan for a last-time buy or identify a replacement drive that fits the same footprint and power range. The closest functional peer in the same series is the ACS800-U1-0006-5, which shares the U1 frame but carries a higher output current rating — verify the motor nameplate and application before substituting.
