It uses the standard 0.100" (2.54 mm) pitch — the same grid as breadboards and perfboards — so the footprint lines up with common prototyping layouts. Rated 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts (78.7 µin of tin on the mating surface). The through-hole solder tails are 0.100" (2.54 mm) long, and the overall contact length is 0.425" (10.80 mm). Operating temperature range is -65°C to 130°C, and the thermoplastic housing carries a UL94 V-0 flammability rating.
Tin is fine for a one-time board assembly or occasional rework; if you need frequent connect/disconnect, you'd want a gold-plated sibling. The 10 positions are fully loaded — no empty spots to track.
