What pin diameter does 2-331677-6 accept?
This PCB pin socket accepts pin diameters from 0.030" to 0.033" (0.76 mm to 0.84 mm).
How does the closed bottom affect installation?
The closed-bottom design means the socket has a solid floor — solder won't wick up into the contact area during wave or hand soldering. That keeps the pin-entry zone clean and prevents the pin from bottoming out on a solder ball. The mounting hole diameter is 0.062" to 0.063" (1.57 mm to 1.60 mm), so drill or spec the PCB accordingly.
Temperature range and termination
Termination is solder — the no-tail body sits flush on the board, and the 0.138" overall length keeps the profile low. Bulk packaging means you get loose parts, not a tape-and-reel; fine for hand assembly or low-volume builds.
