Pin socket with a 0.260" socket depth
The 0391-0-15-80-07-80-10-0 is a Mill-Max 0391 series PCB pin socket, no tail, solder termination, accepting pin diameters from 0.065" to 0.082" (1.65 mm to 2.08 mm).
Dimensions that set the board hole pattern
The socket depth is 0.260" (6.60 mm), flange diameter 0.189" (4.80 mm), and overall length 0.309" (7.85 mm). The mounting hole diameter is 0.159" (4.04 mm) and the pin hole diameter is 0.088" (2.24 mm) — the two dimensions together define the PCB drill pattern and the mating pin clearance.
