Board Fit and Mating Half
The 78208-104HLF: The friction lock feature on the header requires the matching receptacle with a locking ramp — standard Mini-PV crimp housings carry this interface.
Contact Plating and Cycle Life
The contact base is phosphor bronze, chosen for its spring properties and resistance to stress relaxation under repeated deflection. The square pin profile (0.025" square typical for this pitch class) provides a consistent four-point contact with the receptacle terminal.
Environmental and Material Ratings
A keying slot in the housing prevents mis-mating with receptacles that lack the matching key — useful when multiple similar headers are placed on the same board and the harness must go to the correct position.
