The +K466 suffix is part of the order string as listed, and the drive is keyed to ABB as the manufacturer, which is the first thing to confirm when a call comes in asking for an ACS550 spare. ## On the second-source question Buyers hunting a modern functional second-source often land on the ACS580-01-031A-2; it is part of ABB's newer all-compatible drive platform, but it is a different frame at 2.99 kg and a different series — it is not a panel-drop-in for a cubicle that was laid out around the ACS550, and the parameter set, terminal map, and fieldbus options do not carry across without rework. ## Sourcing posture For a panel that was originally designed around an ACS550-U1-04A1-4+K466, the practical procurement angle is to keep the order code intact in the BOM and treat the ACS580 family as a separate engineering decision rather than a substitute — specify the original code, attach the wiring diagram and parameter file to the RFQ, and the panel stays a clean swap on the day it is needed.","metaTitle":"ABB ACS550-U1-04A1-4+K466 Motor Drive, 4.54 kg","metaDescription":"ABB ACS550-U1-04A1-4+K466 ACS550 series motor drive, 4.54 kg, sourced to order against an RFQ for legacy ACS550 builds.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["AC Drives (VFD)"],"specifications":{"Part #":"ACS550-U1-04A1-4+K466","Weight":"4.54 kgs","Category":"Drives","Sub Category":"Motor Drives","Top Category":"Motors & Motor Controls","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1,687.69","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://aoctrl.com/api/mcp/products/ACS550-U1-04A1-4%2BK466/alternatives.json"},"ai":{"faq":[{"question":"Can the ACS550-U1-04A1-4+K466 be swapped for an ACS580-01-031A-2 without rewiring?","answer":"No — the ACS580-01-031A-2 is a different ABB series in a different frame at 2.99 kg, and the terminal map and parameter set do not carry across as a panel-drop-in."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/ACS550-U1-04A1-4~3K466","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/abb/ACS550-U1-04A1-4~3K466 when reusing this data.
