Pin Diameter and Contact Fit
The 5050865-6: This socket accepts a pin diameter range of 0.034" to 0.041" (0.86 mm to 1.04 mm) — the most common range for 0.025" square posts and round header pins used in wire-to-board and board-to-board interconnects. The beryllium copper contact material provides consistent spring force over repeated insertions, and the 100.0 µinch tin plating on the contact finish protects against fretting corrosion in moderate environments.
Temperature Range and Application Fit
Rated from -65°C to 126°C, this socket covers the full automotive underhood and industrial cabinet thermal envelope without requiring a derating curve. The open-bottom feature allows the pin to pass through the socket body, which is useful when the mating pin extends beyond the socket length.
Termination is solder with no tail — the socket body sits flush against the PCB surface after soldering. The mounting hole diameter required is 0.072" (1.83 mm), and the overall length is 0.260" (6.60 mm) with a socket depth of 0.247" (6.27 mm). This low-profile design suits tight z-height budgets in stacked board assemblies.
