Product details

Board-to-Board Mezzanine Header — Obsolete, Sourced to Order

The Hirose DF12D(3.0)-40DP-0.5V(81) is a 40-position surface-mount header from the DF12 series, designed for board-to-board mezzanine stacking. It uses outer shroud contacts on a 0.020" (0.50mm) pitch in two rows, with a mated stacking height of 3mm — a compact footprint for parallel PCB interconnects in tight z-height budgets.

Key Specs for the Fit Check

The 40 positions match a 40-circuit BOM line; the two-row layout keeps the connector width manageable.

Termination is surface-mount only; no through-hole option for this variant.

Frequently asked questions

Where can I buy the DF12D(3.0)-40DP-0.5V(81)?

Submit an RFQ for your quantity and target lead time.

Is DF12D(3.0)-40DP-0.5V(81) obsolete?

Yes, the lifecycle status is Obsolete. Hirose no longer manufactures this exact order code. For BOM continuity, source it through the surplus channel or evaluate alternative Hirose DF12 variants with the same pitch and stacking height.

What is the stacking height of DF12D(3.0)-40DP-0.5V(81)?

The mated stacking height is 3mm. This sets the board-to-board gap in a mezzanine configuration — confirm it clears any components on the facing board surfaces.
