Right-angle header with board lock
The 1-1903328-4 is the 4-circuit member of TE's Dynamic D-4200 header line, a single-row shrouded header with a detent lock for wire-to-board connections. It carries gold-plated mating contacts rated 250 V, mounts through-hole right-angle, and includes a board lock for retention during soldering.
Series & positions
The 1-1903328-4's 4 positions sit at the low end of the Dynamic D-4200 single-row header range — the 0.250" pitch and board-lock footprint are shared across the series, so match the position count to circuit count.
