With a 0.016\" (0.40mm) pitch and two rows of gold-plated center strip contacts, it mates with the matching DF40 header to create a low-profile interconnect for compact electronics. The 0.057\" (1.45mm) height above board keeps the assembly thin, while the supported mated stacking heights of 1.5mm, 3mm, and 4mm give the layout engineer options for z-height budget across different board gaps. ## Position Count and Pitch — Fit Check The 90 positions at 0.40mm pitch mean this connector packs high density into a small board footprint. No footprint change needed when scaling between 80, 90, or 100 positions in the same DF40C family. ## Stacking Height Flexibility The 1.5mm, 3mm, and 4mm mated stacking heights come from pairing this receptacle with different DF40 header heights. That range covers tight handheld-device gaps at the low end and more generous spacing for mid-board component clearance at the high end. The header height selection determines the final stack — the receptacle side stays constant at 0.057\" (1.45mm) above the PCB. ## Mounting and Contact Finish Surface-mount termination with gold-plated contacts. SMT mounting suits automated pick-and-place lines; the Tape & Reel packaging option feeds directly into the placement machine.","metaTitle":"Hirose DF40C-90DS-0.4V(58) 90-Position 0.40mm Pitch","metaDescription":"Hirose DF40C-90DS-0.4V(58) receptacle, 90 positions, 0.40mm pitch, 1.45mm above-board height.
