Product details

40-Position, 0.50mm Pitch Board-to-Board Receptacle

The Hirose DF12A-40DS-0.5V(80) is a 40-position receptacle with center strip contacts from the DF12 series, designed for board-to-board mezzanine stacking. The connector sits 0.106" (2.70mm) above the board surface and supports mated stacking heights of 3.5mm, 4mm, or 5mm, giving the board layout engineer flexibility in z-height budget between parallel PCBs.

The 40 circuits at 0.50mm pitch demand careful PCB layout — the routing density between pads is tight, and the dual-row footprint requires the matching DF12 series header (typically a DF12A or DF12C header with 40 positions) to complete the mezzanine connection.

Frequently asked questions

What is the direct replacement for DF12A-40DS-0.5V(80)?

No official direct replacement order code is recorded for the DF12A-40DS-0.5V(80). For a new design requiring the same 0.50mm pitch and 40 positions, evaluate current Hirose DF12 series variants such as the DF12C or DF12E families, which maintain the same footprint and stacking height options. Confirm the mating header and board layout compatibility before substituting.

What is the height above board of DF12A-40DS-0.5V(80)?

The DF12A-40DS-0.5V(80) sits 0.106" (2.70mm) above the board surface. It supports mated stacking heights of 3.5mm, 4mm, or 5mm, depending on the matching header selected.
