Gold Mating Finish and Contact Design
The 77313-101-14LF: The mating finish is 30 µinch gold over nickel on phosphor bronze contacts — this plating grade is specified for corrosive environments or applications requiring frequent disconnect/reconnect. The tin-plated solder tails (78.7 µinch) are compatible with standard wave-solder processes. The push-pull fastening type and unshrouded design mean the header relies on the mating connector's latch or friction for retention — suitable for low-vibration bench equipment or card-edge applications where the board is fixed.
