What this 10-position header does that an unshrouded pin strip cannot
The 1-647676-0 is a single-row, right-angle header from TE's Economy Power series, with 10 positions on a 3.96mm pitch. The one-wall shroud and friction lock keep the mating housing seated under vibration — something a bare pin strip cannot guarantee. Rated 7.5A per contact at 250VAC, this header suits moderate-power board-to-wire connections in lighting and industrial control panels. The tin-on-tin contact finish is cost-effective for applications that do not demand high mating-cycle counts.
The 3.96mm pitch and 10 positions define the PCB footprint — the right-angle solder tails extend 0.142" (3.60mm) past the board surface. The through-hole termination requires drilled holes matching the square pin cross-section. Insulation height is 0.339" (8.61mm) above the board, and the mating pin length is 0.338" (8.59mm) — enough to engage a standard Economy Power receptacle housing fully.
