The 1-179188-3: Rated 250 V with gold-plated mating contacts (30.0 µin), the header mounts surface-mount right-angle and terminates by solder — the 3.81 mm pitch and single-row layout suit compact power or signal distribution on a single-layer board.
Position count and footprint
The 1-179188-3 carries 8 positions loaded all in a single row at 3.81 mm pitch — the same pitch and right-angle SMT footprint are shared across the Dynamic D-3100 series, so the position count alone determines the circuit fit.
