The 2842126-2: The unshrouded pins mate with any AMPMODU 2.00 mm receptacle or IDC socket that accepts a 0.64 mm square pin. Through-hole solder termination with 2.79 mm post length — fits a 1.6 mm standard PCB thickness with room for a wave-solder fillet.
Contact Finish and Mating Cycles
Mating surface is gold over copper alloy at 3.94 µinch (0.100 µm) — a flash gold finish suited for low-cycle board-to-board interconnects where the header is mated a few times during assembly and then left connected. For applications requiring more than 50–100 mating cycles, the 1376779-2 sibling carries 8.00 µinch gold on the mating surface — roughly double the wear life.
RoHS3 compliant. No known direct replacement from TE — the 1376779-2 is a functional peer with the same pitch and pin count but thicker gold plating and a different package (Box vs Tube).
