0.40 mm Pitch, 50-Circuit SlimStack Plug for Tight Mezzanine Stacking
This plug uses outer shroud contacts and is intended to mate with the corresponding SlimStack 204928 receptacle to achieve a mated stacking height of 3 mm. The 0.093" (2.35mm) height above board of this plug, combined with the receptacle height, sets the total gap between parallel PCBs. It is a surface-mount component, and the inclusion of pick-and-place features and solder retention tabs makes it suitable for high-volume automated assembly lines where reflow process reliability is critical.
This plug mates with the Molex SlimStack 204928 series receptacle (for example, order code 2049280201). The mated pair yields a stacking height of 3 mm, a dimension that must be matched to the clearance between the two PCBs in the assembly. The 0.40 mm pitch means the PCB footprint requires precision alignment; the solder retention features help maintain that alignment during reflow.
