Product details

Solder retention pads on the body anchor the plug during reflow and resist shear from cable strain or vibration in the field.

The 0.6mm mated stacking height is the key mechanical constraint: the receptacle half must also be a 0.6mm stack member for the pair to mate correctly. If your board-to-board gap is 0.8mm or 1.0mm, this plug won't reach — you'd need a different stack height variant in the series.

Frequently asked questions

What is the mating height for the Molex 5050703420?

Does the 5050703420 have solder retention features?

Yes, it includes solder retention pads that anchor the plug to the PCB during reflow and help resist shear forces from vibration or cable strain.
