What the 1.50 mm pitch and tin plating mean for your board
The 5025841260: At 1.50 mm pitch, the 12 positions fit in a board footprint roughly 18 mm wide — tight enough for compact lighting or medical modules, but not so fine that you need a micro-via fan-out. The tin-on-tin contact finish (39.4 µin on both mating and post sides) is standard for moderate-cycle applications; expect a few hundred mate cycles before the tin oxide layer starts to increase contact resistance.
