The 0.100" pitch and 0.100" row spacing place this header on a standard 2.54mm grid — the board footprint is a straightforward 2-row through-hole pattern with 70 plated holes. The 0.190" (4.83mm) mating pin length gives a solid wipe depth into the receptacle contact, and the 0.120" (3.05mm) solder post length is sized for standard 1.6mm-thick PCBs. The UL94 V-0 flammability rating on the black insulation body means the header is acceptable for equipment that requires a flame-retardant housing inside an enclosure — common in industrial and telecom applications where the connector sits on a backplane or I/O card.
