Availability and current pricing are confirmed at quote time through independent distribution channels."},{"question":"When sourcing S273K8A, what's the closest functional second-source — S273-K6A?","answer":"The S273-K6A is a peer in the same S273 family with identical weight (0.36 kgs) and category. The key difference is the current rating — the K6A is a 6 A variant versus the K8A's 8 A. Both share the same DIN-rail footprint and series design, so a panel wired for one can accept the other without rewiring, provided the ampacity matches the load."},{"question":"Will S273K8A drop into a panel that was specified around S273-K6A without rewiring?","answer":"Yes. Both parts share the same S273 series DIN-rail footprint and 0.36 kg mass. The S273-K6A is a 6 A version; the S273K8A is 8 A. Mechanical fit is identical — no rewiring needed as long as the circuit's ampacity requirement matches the 8 A rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/abb/S273K8A","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/S273K8A when reusing this data.
