The 11.04mm mated stack height is fixed by the receptacle's insulation height of 0.275" (6.99mm) plus the mating header's pin length — confirm the header's post length to stay within the stack budget. The 0.118" (3.00mm) solder post length suits standard through-hole PCB thicknesses (1.6mm typical) with enough tail for a reliable solder fillet on the bottom side.
Within the Dubox series, the closest alternative would be any other 4-position, dual-row, 0.100" pitch receptacle with the same 11.04mm stack height and gold plating grade.
