Board Footprint and Fit
The 4-103239-0-02: In a test fixture or a field-service harness that gets mated a few hundred times, the gold interface resists fretting corrosion and keeps contact resistance stable. The post finish is tin-lead, which solders well to standard PCB pads.
Mating and Series Compatibility
This is a breakaway header from the AMPMODU Mod II series — mates with AMPMODU Mod II receptacles and compatible 0.100-inch pitch IDC sockets. The 2-position count is minimal — often used for power jumpers, sensor breakouts, or signal link pairs.
