The receptacle itself sits 0.057\" (1.45mm) above the board surface, so the clearance under the connector body is tight. That 0.05mm delta between the board standoff and the mated height means the mating header's profile must be accounted for in the stack-up budget. The gap is where it lives or dies — if your board-to-board spacing is anything other than 1.5mm, this part won't seat properly. ## Surface Mount Termination and Packaging The connector is surface mount, with Tape & Reel and Cut Tape packaging options. The SMT termination suits automated pick-and-place assembly for high-volume production. The 0.40mm pitch demands precise solder paste deposition and reflow profile control — misregistration at this density can bridge adjacent pads.","metaTitle":"Hirose DF40C-30DS-0.4V(51) Receptacle, 30 Pos, 0.40mm Pitch","metaDescription":"Hirose DF40C-30DS-0.4V(51) 30-position receptacle, 0.40mm pitch, 1.5mm stack height, gold contacts.
