The 0.016\" (0.40 mm) pitch packs 90 circuits into a two-row layout, which keeps the PCB footprint narrow but demands fine-line routing — expect trace/space widths below 0.20 mm on the mating pads. ## 1.5 mm stack height — fixed mezzanine gap The mated stack height is a fixed 1.5 mm, set by the connector body height of 0.053\" (1.35 mm) plus the mating interface. This suits ultra-thin assemblies where the PCB pair must sit close. ## SMT termination with solder retention Surface-mount termination with integral solder retention features — the part has small metal tabs that wick solder during reflow, anchoring the connector to the board pads. Tape & Reel packaging supports automated pick-and-place.","metaTitle":"Molex 0513380974 SlimStack 51338, 90 Pos, 0.40mm Pitch","metaDescription":"Molex 0513380974 SlimStack 51338 receptacle, 90 positions, 0.40mm pitch, 1.5mm stack height.
