The 0.57 mm height above board (0.022\") and 0.7 mm mated stack height together define the z-budget for the enclosure: a 0.7 mm gap between the two PCBs when mated. ## Solder Retention and Surface-Mount Termination This plug is surface-mount only, terminated by reflow soldering. The solder retention feature — integral pads on the connector body — anchors the part during reflow and provides additional shear resistance after soldering, which matters when the mated assembly sees handling or vibration in a portable device. No through-hole posts; the hold-down is purely SMT. The plug mates with the matching SlimStack receptacle (same 0.40 mm pitch, same 16 positions); the outer shroud on the plug aligns with the receptacle's inner shroud for blind-mate guidance.","metaTitle":"Molex SlimStack 5035521680, 16-Pos Plug, 0.40mm Pitch","metaDescription":"Molex 5035521680 SlimStack plug, 16 positions, 0.40mm pitch, 0.57mm board height, gold contacts, SMT, RoHS3.
