Board layout and footprint fit
The 3-794679-8: This is an 8-position, dual-row header on 3.00mm pitch — the same row-to-row spacing of 3.00mm means the PCB footprint is a 2x4 grid with 3.00mm centers in both axes.
Mating and locking
The shrouded 4-wall housing with locking ramp mates with the Micro MATE-N-LOK receptacle housing (e.g., 3-794656-8 for 8 positions). The ramp locks audibly on full engagement and resists accidental unmating under vibration. The header accepts male pins from the receptacle side — the contact interface is gold-on-gold when using the matching gold-plated receptacle terminals.
