Pin diameter range and contact design
The 2-330808-8: This socket accepts pin diameters from 0.013" to 0.020" (0.33mm to 0.51mm), making it a tight-fit choice for standard round pins in that range.
Closed bottom and solder termination
Closed bottom means the socket has a solid floor — during wave soldering the solder paste cannot wick up into the barrel and block the pin entry. The socket terminates by soldering the outer barrel into a plated through-hole with a mounting hole diameter of 0.040" to 0.041" (1.02mm to 1.04mm). Overall length is 0.142" (3.61mm) and the socket depth is 0.130" (3.30mm), so the pin needs to enter at least that far to make full contact.
Packaged in bulk, which suits hand-placement or vibratory bowl feeding for high-volume assembly lines.
