It uses the standard 0.100" (2.54 mm) pitch on both rows and contacts, making it a drop-in fit for legacy and new board-to-board designs that need a dense but serviceable interconnect. Rated 5 A per circuit at 110 V, with gold or GXT™ plating at 30.0 µ" (0.76 µm) on the mating surface, this header handles repeated mating cycles without contact fretting — the plating grade is the real duty spec here, not the headline current.
The 0.100" pitch and 0.100" row spacing are standard across the series, so the footprint is consistent; the difference is purely the pin count.
