Pitch and footprint — the board-level constraint
At this pitch, the trace escape between pads is tight enough that a 4-layer board is not required, but the routing density is higher than a 0.100-inch header — plan the via fan-out accordingly. 20 positions in a dual-row layout means the connector occupies roughly 20 mm of board edge.
Shrouding and latch — vibration-proof mating
The latch holder locks the pair together — in an automotive or industrial cabinet subject to vibration, this prevents the connector from walking loose. The board guide feature further aids alignment during assembly, reducing the risk of stubbing pins when the harness is mated blind.
Voltage and temperature — insulation class
Rated 250 VAC/DC, the header suits signal and low-power distribution within equipment enclosures.
