Its 0.100-inch (2.54 mm) pitch matches standard 0.100-inch grid prototyping and production boards, so the footprint is a drop-in for many existing layouts.
The single-wall shroud provides keying guidance during mating but leaves the top of the contacts exposed — a consideration if the assembly sees debris or conductive dust.
