The CT header is a right-angle variant, while this one is vertical through-hole — choose the orientation that fits your board-edge cable exit. Against the 1-2232960-3 (also 2.50 mm pitch but 3 positions), this 4-position version adds one more circuit for applications needing an extra signal or power line. Both use tin contacts and a shrouded 4-wall design, so the mating receptacle family is the same.","metaTitle":"4-1971798-1 TE Connectivity Header, 4 Pos, 2.5mm Pitch","metaDescription":"TE Connectivity AMP Connectors Grace Inertia GIC header, 4 positions, 2.50mm pitch, shrouded 4-wall, tin contacts, UL94 V-0.
