Right-angle SMT header for tight board layouts
The 1-177662-2: This is a 5-position, single-row header from the Dynamic D-3100 series, with a 3.81mm pitch and right-angle surface-mount termination. The shrouded 4-wall housing and detent lock give it a positive mate with the matching D-3100 receptacle — no secondary latch needed.
What the 3.81mm pitch and gold plating mean on the bench
At 3.81mm pitch, this header gives you more room between traces than a 2.54mm or 2.00mm part — useful if you're routing power alongside signal on a 2-layer board. Compared to the through-hole sibling 1-1871673-2 (2-row, 2.50mm pitch, tin-plated), this part is a single-row, wider-pitch, gold-contact option for signal integrity in moderate-vibration environments. The detent lock is the same style, but the SMT body and gold plating make this one better suited for automated assembly and corrosive atmospheres.
