It uses a 0.100" (2.54 mm) pitch on both the mating and row spacing, which matches the standard 0.100-inch grid common in legacy and current PCB layouts.
The 110 V voltage rating aligns with the creepage distance available on a 0.100-inch pitch unshrouded header; for higher voltage applications, a shrouded header with deeper insulation would be needed.
Mounting and board layout considerations
The right-angle through-hole termination requires a plated through-hole footprint on a 0.100-inch grid. The 0.125" (3.18 mm) post length is short — typical for a standard PCB thickness of 0.062" to 0.093" — and the 0.230" (5.84 mm) mating pin reach gives a positive engagement depth into the mating receptacle.
