The 70 positions across two rows means 35 contacts per row, and the trace escape from the footprint requires micro-vias or tight neck-downs on the inner layers. The shielded construction tells you this connector is intended for signal paths that need isolation from radiated noise, not just a simple power interconnect. ## 3mm Stack Height — What It Means for Board Layout This is not adjustable — the connector body sets the gap. The solder retention feature provides additional mechanical hold during reflow, which matters for a fine-pitch connector where tombstoning or skew from paste reflow could misalign the contacts. ## Mating Connector and Series Fit The DF40 series uses a common 0.40mm pitch and 3mm stacking height variant across multiple position counts. The base product number is DF40G, and the (3.0) in the part number indicates the 3mm stack height option. For a 70-position mate, the matching plug would be a DF40 series header with the same (3.0) stack height designation — the 70-position count is the critical match point, as a 48-position plug (like the DF40GB(3.0)-48DS-0.4V(58)) will not align.","metaTitle":"Hirose DF40GB(3.0)-70DS-0.4V(58) Receptacle, 70 Pos","metaDescription":"Hirose DF40 series receptacle, 70 positions, 0.016\" (0.40mm) pitch, gold plating, shielded, 3mm stacking height.
