The mated stacking height is 2mm, and the height above the board sits at 0.077\" (1.95mm). ## 80 Positions at 0.40mm Pitch — Routing Density Trade-Off Eighty positions on a 0.40mm pitch means the trace breakout from the connector footprint is the main layout constraint. You're routing 40 signals per row through a narrow land pattern — expect to use micro-vias or thin trace widths to escape the inner rows. ## Gold Contacts and SMT Termination The contacts carry a gold finish with a thickness of 2.00µin (0.051µm) on the mating surface. That's a flash-grade plating — adequate for the moderate mating cycle counts typical of internal board-to-board connections in consumer and portable electronics. The termination is surface-mount only, so the reflow profile needs to match the 1.95mm component height. Tape & Reel or Cut Tape packaging is available, which suits both prototype runs and volume pick-and-place lines. ## Active Production and RoHS Compliance It is also RoHS Compliant per the listing.","metaTitle":"Hirose DF40C(2.0)-80DS-0.4V(51) Receptacle, 80 Pos","metaDescription":"Hirose DF40C(2.0)-80DS-0.4V(51) receptacle, 80 positions, 0.40mm pitch, 2 rows, gold contacts, 1.95mm height.
