Same-family cross-shop
The ACS380-040S-04A0-4: The ACS380-040S-06A9-2 shares the 1.81 kgs weight and Motor Drives placement with the seed MPN. The order-code suffix is the differentiator on the panel cut-out, not the mass.
Sourcing posture
Only the ABB brand assignment is on record for the seed MPN; no lifecycle status or successor order code is logged. Until supply channel confirmation arrives, quote the part to order against an RFQ rather than assume active or obsolete.
