What the order code resolves to
The ACS880-104-0018A-5+0J41: The ACS880-104 form factor is the modular / IGBT-module member of the ACS880 family — it is designed to be paired with the supply and control units in the same platform rather than shipped as a wall-mount standalone drive, which is what distinguishes it from the ACS880-01 codes a panel-builder will see in the same family. Mass is 2.53 kg for the module as listed — light enough that a single technician can handle it, but the part is still a power-stage module, so the panel-side mounting hardware, cooling path, and DC-bus work are what the application has to budget for, not the lift.
Reading the suffix and the family it sits in
Treated as an inverter module rather than a complete drive, the ACS880-104-0018A-5+0J41 inherits the platform's control and safety wiring conventions — the fieldbus, encoder, and I/O map are determined by the host control unit and the parameter file, not by the inverter module alone, so a panel layout that was wired against the modular platform reuses the same cabling logic. The +0J41 option code is a single configuration token — when the BOM is being frozen it should be specified exactly as written, with the +0J41 suffix carried through to the purchase order; truncating it drops the configured features and produces a different SKU on the same -104 chassis.
What the ACS880-01 peers are not
The ACS880-01-11A0-5, ACS880-01-07A6-5, and ACS880-01-021A-5 sit in the wall-mount ACS880-01 enclosure family, not the ACS880-104 modular line — they ship as standalone drives with their own keypad, control unit, and IP-rated housing, and they do not drop into a panel that was built around an ACS880-104 inverter module without reworking the mounting footprint, the control-unit wiring, and the fieldbus mapping. Asking whether the ACS880-104-0018A-5+0J41 can be substituted into a panel specified around an ACS880-01-11A0-5 is the wrong cross-shop — the two codes belong to different ACS880 sub-families, so any swap is a redesign of the panel layout and parameter file rather than a one-to-one replacement.
Sourcing posture for the BOM line
The panel-shipping mass of 2.53 kg is the figure to use in the BOM and the freight documentation, not a family-wide ACS880 weight; the ACS880-01 peers on file are heavier at 4.54 kg, 6.35 kg, and 7.71 kg respectively because they ship as complete drives with a housing and local control panel.
