Product details

0.40mm Pitch, 60-Position Mezzanine Receptacle — 2mm Stack Height

The Hirose DF40C(2.0)-60DS-0.4V(51) is a 60-position receptacle from the DF40 series of board-to-board mezzanine connectors. It uses a 0.016" (0.40mm) pitch dual-row layout with center strip contacts, designed for parallel PCB stacking at a mated height of 2mm.

60 vs 70 Positions — Same Footprint, Different Circuit Count

The DF40C(2.0)-60DS-0.4V(51) shares the same 0.016" (0.40mm) pitch, 2mm mated stack height, and gold contact finish with the 70-position DF40C(2.0)-70DS-0.4V(51). Choose the 60-position variant when the BOM calls for exactly 60 signal lines; the 70-position sibling covers a higher-density routing need at the same z-height.

Surface-Mount Termination — Fine-Pitch Soldering Required

This receptacle is surface-mount only, with no through-hole retention. The 0.40mm pitch demands a precise solder paste stencil and reflow profile — standard wave-solder processes will bridge the fine-pitch contacts. Alignment features on the connector body help register the pair during assembly, but the fine pitch leaves little room for misalignment.

Frequently asked questions

What is the mated stacking height of DF40C(2.0)-60DS-0.4V(51)?

The mated stacking height is 2mm. This is a fixed dimension set by the connector body — the mating header must be from the DF40 series with the same height code to achieve the correct board-to-board spacing.
