Rated 0.5 A per contact at 50 V with tin-plated mating contacts, it handles low-current signal duty in space-constrained board stacking. ## Series footprint and position count The Fine Pitch series shares the same 0.049\" (1.25 mm) pitch and 0.049\" (1.25 mm) row spacing across all position counts — the 14-position 4-175638-4 fits the same board footprint as other dual-row members, so the position count alone determines circuit matching.","metaTitle":"TE 4-175638-4 Receptacle, 14 Pos, 1.25mm Pitch","metaDescription":"TE Fine Pitch 4-175638-4 receptacle: 14 positions, dual row, 1.25 mm pitch, 0.5 A, 50 V, tin-plated contacts, SMT, UL94 V-0.
