Board-mount header for Mini-Universal MATE-N-LOK receptacles
The 1-770621-0: This is a 12-position, 2-row vertical header from the Mini-Universal MATE-N-LOK series, on a 0.163" (4.14mm) pitch that matches the standard receptacle in the same family. The four-wall shrouding and locking ramp keep the mating connector aligned and latched — no wiggle, no intermittent contact in a vibrating panel.
Pitch, positions, and what mates with it
Both the mating pitch and row spacing are 0.163" (4.14mm), so the footprint is a simple 2×6 grid — no staggered holes. Compared to the 20-position ATX-series header 4-1775099-7, this part has fewer circuits (12 vs 20) and a slightly tighter pitch (4.14mm vs 4.20mm), so they are not footprint-interchangeable.
