Compared to the 8-position 71609-304LF or the 40-position 71609-320LF, the 18-position variant fills a mid-density BOM slot where neither a small nor a large header fits the circuit count. Row spacing is also 0.100" (2.54mm), so the PCB layout must accommodate a 2.54mm grid for both rows.
Amphenol ICC's Dubox™ series offers matching headers; confirm the pin length and stacking height from the mating header's datasheet.
Yes, the manufacturer lists it as RoHS compliant.
The insulation height is 0.230" (5.85mm) above the PCB — this sets the clearance under the receptacle for board-to-board stacking.
