Footprint and mounting decision
The 5600200320: This is a 3-position, single-row header on a 2.00 mm pitch — the board footprint needs one row of 3 through-pads spaced 2.00 mm centre-to-centre. The surface mount termination means the part reflows with the rest of the SMD components; no wave-solder step required.
Mating half and stack height
The header mates with a DuraClik receptacle (same series) that accepts 20-24 AWG wire; the latch lock engages with the corresponding ramp on the receptacle.
