34-position dual-row board-to-board receptacle
The 1-215307-7: The through-hole termination with kinked pins gives a solid solder joint for moderate vibration environments, and the gold mating finish (31.5µin) handles repeated mating cycles without corrosion.
Pitch, positions, and plating for BOM fit
With 34 positions loaded across two rows at 0.100" pitch, this receptacle matches standard 0.100" square-pin headers — confirm your header has 34 pins in a dual-row layout. The gold-on-mating, tin-on-post contact finish (31.5µin gold, 98.4µin tin post) suits applications where the connector is mated and unmated more than a few times; the tin tails solder reliably to standard PCB pads.
