Board Fit and Routing at 0.156" Pitch
The 87633-4: This 4-position unshrouded header from the AMPMODU Mod I series uses a 0.156" (3.96 mm) pitch — wide enough to route a single trace between pads on a standard 1 oz copper board without necking down.
The through-hole solder termination is straightforward for hand or wave-solder assembly; the 0.405" (10.29 mm) mating length gives the receptacle contact beam enough wipe to establish a low-resistance interface.
