Board Layout and Fit Check
The 77315-401-18LF: The 0.100" pitch sets the board footprint — each pin lands on a 2.54mm grid, which is compatible with standard perfboard and prototyping layouts. The 0.225" (5.72mm) mating pin length provides enough insertion depth for most standard receptacles. The 0.101" (2.57mm) solder post length is short — confirm the PCB thickness and plated-through-hole depth allow the solder tail to protrude enough for a reliable fillet.
