Board-to-Board Right-Angle Receptacle at 0.050" Pitch
The 0.050" (1.27 mm) mating pitch allows dense routing on the PCB, while the 0.100" (2.54 mm) row spacing keeps the layout manageable for standard 2.54 mm grid designs.
Gold Mating Surface and 1 A Current Rating
The post tails are tin-plated (150.0 µin) for reliable solder wetting.
Comparison with Peer 1376775-2
The closest functional peer is 1376775-2, also a TE AMPMODU System 50 receptacle, but with 5 positions and a lower gold mating finish of 8.00 µin (0.203 µm) versus 30.0 µin on the 5-103911-1. The 5-103911-1 offers three times the circuit count and thicker gold for higher mating-cycle duty.
