When sourcing S273K8A, what's the closest functional second-source — S273-K6A?
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.
Will S273K8A drop into a panel that was specified around S273-K6A without rewiring?
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.
