Product details

0.50 mm Pitch Mezzanine Header — 20 Positions, 4 mm Stack

The Hirose DF12E(4.0)-20DP-0.5V(81) is a 20-position, 2-row board-to-board header from the DF12 series, designed for parallel PCB stacking at a 4 mm mated height.

Obsolete — Sourcing Path

No direct replacement order code is listed on the record.

The header mates with any DF12 series receptacle that matches the 20-position, 0.50 mm pitch layout. Surface-mount termination requires reflow soldering; the Tape & Reel packaging suits automated pick-and-place assembly.

Frequently asked questions

What is the replacement for DF12E(4.0)-20DP-0.5V(81)?

What is the stacking height of DF12E(4.0)-20DP-0.5V(81)?

The mated stacking height is 4 mm. This is the board-to-board spacing when the header is mated with its matching DF12 series receptacle.
