Two-pin breakaway for tight board layouts
The 826631-2: It's a breakaway style — you snap it to length from a longer strip, so the 2-position version is the smallest unit you can get in this series.
What the 5A rating means in practice
Rated 5A per contact. That's the current limit at 25°C ambient with all positions loaded — typical for a 2.54mm pitch unshrouded header with gold-plated mating surface and tin-plated posts. The unshrouded design means no polarization key; you rely on the mating housing's alignment for correct orientation. The gold mating finish (3.90µin) handles repeated mating cycles better than tin, so this header suits applications where the board gets disconnected a few times during service life.
