It uses a dual-row, center strip contact arrangement on a 0.40mm pitch — one of the densest pitches in the SlimStack family. The mated stack height is 1.35mm, which means the two PCBs sit that close together once the matching SlimStack header is engaged. ## What the 0.40mm Pitch and 70 Positions Mean for Board Layout At 0.40mm pitch, the signal density per millimeter of board edge is high — 70 circuits in a dual-row footprint that fits in roughly 14 mm of PCB real estate. That density drives the trace escape pattern: you will need micro-vias or tight via-in-pad routing to fan out the inner-row signals.","metaTitle":"Molex SlimStack 0513380774, 70-Pos 0.40mm Pitch Receptacle","metaDescription":"Molex 0513380774 SlimStack 51338 receptacle, 70 positions, 0.40mm pitch, 1.35mm stack height, SMT, gold contacts.
