Product details

Board-to-Board Signal Header for Dense Interconnects

The 87409-120LF: The wide operating range from -55°C to 130°C suits equipment that sees thermal cycling in military or industrial environments.

Mating Connector and Cable Compatibility

The 87409-120LF is not designed for standard ribbon cable or IDC termination — it is a surface-mount header intended for PCB-to-PCB connection. For cable-to-board applications, a different connector family (such as a wire-to-board header with crimp terminals) would be needed.

It is supplied in tube packaging for automated pick-and-place. No official successor or pin-compatible alternative is recorded from the original manufacturer.

Frequently asked questions

What is the mating connector for 87409-120LF?

The 87409-120LF mates with a Rib-Cage™ III receptacle of the same pitch (1.27mm) and position count (40 positions) to achieve a board-to-board stack height of 6.42mm. The mating half is a surface-mount receptacle from the same series — confirm the exact order code from the Rib-Cage™ III product family.

Is 87409-120LF compatible with standard ribbon cable?

No. This is a board-to-board header with surface-mount termination, designed to solder directly to a PCB. It does not accept ribbon cable or IDC connectors. For cable-to-board connections, look at wire-to-board header families with crimp terminals.
