Product details

Board-Stacking Interconnect for Tight Z-Height Budgets

The DF40C(2.0)-30DS-0.4V(51): The 0.40mm pitch and 2mm mated stacking height let you route dense signal traces between parallel PCBs without forcing a tall enclosure. Gold-plated center strip contacts on a dual-row layout handle the signal count in a compact footprint — the 2.00µin gold flash is a light plating, adequate for the limited mating cycles typical of a factory-set stack height.

Position Count: Matching the BOM Line

At 30 positions, this receptacle sits between the 20-position DF40C(2.0)-20DS-0.4V(51) and the 40-position DF40C(2.0)-40DS-0.4V(51) in the same DF40C sub-family.

Frequently asked questions

What is the mated stacking height of DF40C(2.0)-30DS-0.4V(51)?

The mated stacking height is 2mm, which sets the gap between parallel PCBs in a mezzanine stack. The 0.40mm pitch and surface-mount termination keep the overall board-to-board height compact.

Does DF40C(2.0)-30DS-0.4V(51) have any drop-in replacements?

The 20-position DF40C(2.0)-20DS-0.4V(51) and 40-position DF40C(2.0)-40DS-0.4V(51) share the same pitch and stack height but differ in circuit count — they are not direct substitutes for a 30-position BOM line.

Where can I buy DF40C(2.0)-30DS-0.4V(51)?

This part is sourced to order against your BOM quantity.
