50-position, 2.54mm pitch, dual-row right-angle header
The 1-5103310-0: It is a right-angle through-hole solder termination, designed for board-to-cable/wire applications where a compact, right-angle exit from the PCB is needed. The header is fully shrouded with a 4-wall design and includes a keying slot, which together prevent pin damage during mating and ensure correct orientation with the mating AMP-Latch receptacle.
Current rating and contact finish
Rated at 1 A per contact, this is a signal-level interconnect. The limiting factor is the dense 50-position array, not the contact itself. The mating contact finish is gold or gold-palladium with 15.0 µin thickness, providing reliable performance over repeated mating cycles. The post (solder tail) finish is tin with 100.0 µin thickness, which is standard for through-hole solder joints.
