The 2-173983-5 is a 5-position, single-row IDC connector from TE's CT Amp-In series, designed to terminate discrete 26-28 AWG wires directly to the board — no crimp terminals or ribbon cable needed. The 0.079" (2.00mm) board-side pitch matches the cable pitch, keeping the layout tight for low-density signal runs. The yellow housing gives harness builders a quick visual cue for circuit identification on the board — useful when multiple connectors share the same footprint.
Termination and mounting — what the IDC and right-angle mean on the bench
IDC termination for 26-28 AWG means the wire insulation is pierced by the contact tines as the cover is pressed down — no stripping, no crimping.
