Fine Pitch Header for Dense Board-to-Board Stacking
The 7-175643-2 is a 12-position, 2-row male pin header from TE's Fine Pitch series, designed for board-to-board stacking where PCB real estate is tight. The 1.25mm pitch and 0.049" row spacing set the board footprint — at this density, the 0.5A per-contact current rating is consistent with signal-level duty, not power transmission.
Surface Mount Termination and Board Guide
Termination is solder, surface mount. The insulation material is Polyphenylene Sulfide (PPS), which handles the reflow profile without deformation — PPS has a high melting point and low moisture absorption, suited for lead-free soldering. The header is supplied in a tube.
