Product details

Board-to-Board Stacking Fit – 72 Positions at 2.54mm Pitch

Contact and Termination – Tin-Plated Phosphor Bronze, Through-Hole Solder

The solder posts are 0.118" (3.00mm) long, through-hole termination. The receptacle accepts either bottom or top entry, so it can sit on either the top or bottom board in the stack — the same part number works in either position. This reduces the number of unique line items needed for a two-board mezzanine assembly.

Standard packaging is a tube.

Application Range – Automotive, Industrial, Telecom, General Purpose

The 2.54mm pitch and through-hole termination suit it for environments where vibration is moderate and the board stack is not subject to continuous shock — the push-pull retention relies on contact friction, not a secondary lock.

Frequently asked questions

What is the mated stacking height of the 71991-436LF?

The mated stacking height is 11.04mm. This is the fixed board-to-board gap when the receptacle is mated with its matching header.

What is the pitch and number of positions for the 71991-436LF?

The pitch is 0.100" (2.54mm) with 72 positions in a dual-row configuration. Row spacing is also 0.100" (2.54mm).

What applications is the 71991-436LF suitable for?

The Dubox series is listed for Automotive, General Purpose, Industrial, and Telecommunications applications. The through-hole solder and tin-plated contacts suit moderate-vibration board-to-board stacks.
