4.14mm pitch, 3-position header with board lock
The 770873-1 is a 3-position, single-row header from TE's Mini-Universal MATE-N-LOK series, designed for board-to-wire applications. The 4.14mm pitch sets the PCB footprint and the per-contact current ceiling — the actual current depends on wire gauge, but the housing and contact geometry are built for the series' standard power range. A shrouded 4-wall design protects the male pins during handling and guides the mating receptacle into alignment, reducing the chance of bent pins during assembly. The locking ramp on the header engages with the receptacle latch for a vibration-resistant mate — useful in equipment where the connector sees movement or shock. Without the board lock, the solder joints alone would carry the cable strain — the lock takes that load off the pads.
For RoHS-required builds, check the series for lead-free plating options or confirm the exemption applies.
Mates with Mini-Universal MATE-N-LOK receptacle
This header mates with the 3-position Mini-Universal MATE-N-LOK receptacle housing (e.g., 1-480424-0). The locking ramp on the header snaps into the receptacle latch, and the 4.14mm pitch aligns the contacts. Confirm the receptacle's contact cavity count and terminal type match the circuit count.
