20-Position Single-Row System 50 Receptacle
The 5-104196-5: This is a 20-position, single-row female socket header from the AMPMODU System 50 family — a board-to-board receptacle with a 0.050-inch (1.27 mm) pitch that defines the footprint for routing dense signal lines on a PCB. Gold plating on the mating surface (30.0 µin / 0.76 µm) and tin on the solder tails (150.0 µin / 3.81 µm) balances corrosion resistance during repeated mating cycles with reliable solder-joint wetting.
The 1 A limit is typical for the 1.27 mm pitch and reflects the narrow contact beam cross-section.
