Pin diameter range and contact construction
The 4-5332070-4: This pin receptacle accepts pin diameters from 0.028" to 0.033" (0.71mm to 0.84mm) — a tight window that means your mating pin must fall within that range for a reliable interference fit.
Solder termination and board fit
Termination is solder, with no tail — the socket depth is 0.130" (3.30mm) and overall length 0.143" (3.63mm), so it sits flush in a plated-through hole of 0.072" (1.83mm) diameter. The open-bottom feature allows the pin to pass through the socket body, which helps with alignment during assembly.
