Board-to-wire header at 4.14mm pitch — what the 10-position 2-row layout means for your harness
The 1-770743-0: This is a 10-position, 2-row vertical header from the Mini-Universal MATE-N-LOK series, with a 0.163" (4.14mm) pitch on both the mating and row spacing. The 4-wall shrouding and locking ramp mean it's built to stay mated under vibration — the latch gives an audible click when fully seated, and the shroud protects the pins from damage during handling. The board lock feature holds the header in place during solder and reflow, preventing the part from floating off the pads before the joints solidify. This is a practical advantage on a through-hole part — the lock anchors the header so the pins stay centred in the plated holes.
Mating and termination — what it mates with and how it mounts
This header mates with Mini-Universal MATE-N-LOK receptacle housings (crimp or pre-loaded contacts). The male pins are circular, tin-plated on both mating and post surfaces with 150.0µin thickness. Through-hole solder termination, 0.175" post length — fits standard 1.6mm PCBs. Current rating depends on the wire gauge used in the mating half — the header itself is rated for the series' full current capacity when paired with the correct crimp terminal. Operating temperature range is -20°C to 85°C.
