Board-to-board or cable header with a latch that holds
The 1722861105: This is a 5-position, single-row shrouded header from the Molex Ultra-Fit 172286 series, pitched at 0.138" (3.50 mm). Rated 600 V and spanning -40°C to 105°C, it handles higher-voltage lighting or power distribution without derating at the top end of the temperature range.
Pitch, stack height, and board footprint
Mated stacking height is 26.99 mm — a fixed number, so the mating receptacle's board-to-board spacing is non-negotiable.
