Product details

40-Position, 0.50mm Pitch Mezzanine Header — Now Obsolete

The Hirose DF12(5.0)-40DP-0.5V(86) is a 40-position, dual-row header from the DF12 series, designed for board-to-board mezzanine stacking. It uses a 0.020" (0.50mm) pitch and surface-mount termination, with a mated stacking height of 5mm. This part is now obsolete per the manufacturer's lifecycle status.

What the 5mm Stacking Height and 0.50mm Pitch Mean for Your Layout

The 0.50mm pitch, combined with 40 positions across two rows, defines the board footprint width and the routing channel density underneath the connector. At this pitch, trace escape from inner rows requires via-in-pad or dog-bone fanout on the inner layer.

Frequently asked questions

Where can I buy DF12(5.0)-40DP-0.5V(86) available via RFQ confirmation?

The DF12(5.0)-40DP-0.5V(86) is an obsolete part, so stock is found in the surplus and independent broker channel, not through factory franchise lines.

Is DF12(5.0)-40DP-0.5V(86) obsolete?

Yes, the DF12(5.0)-40DP-0.5V(86) is marked obsolete by Hirose.

What is the mated stacking height of DF12(5.0)-40DP-0.5V(86)?

The mated stacking height is 5mm. This is the fixed z-axis dimension between the two parallel PCBs when the header is mated with the corresponding receptacle.

What is the pin pitch of DF12(5.0)-40DP-0.5V(86)?

The pin pitch is 0.020" (0.50mm). This is a fine-pitch connector, so the board footprint and trace routing must account for the tight spacing.
