Product details

240-Pin DDR3 DIMM Socket — Board Fit and Contact Life

The 78373-0001 is a 240-position DDR3 DIMM socket from Molex's 78373 series, built to the MO-269 standard for DDR3 module interface. The board guide and latches keep the module aligned and locked against vibration, which is critical in rack-mount gear where the DIMM sees shipping shock.

DDR3 Compatibility and Memory Type

This socket is specified for DDR3 SDRAM modules — the 240-pin, 1.00mm pitch interface matches standard DDR3 and DDR3L DIMMs. The memory type designation means the socket's electrical and mechanical profile aligns with JEDEC DDR3 requirements, including the keying notch position that prevents inserting a DDR2 or DDR4 module.

Frequently asked questions

What is the difference between Molex 78373-0001 and 78373-0002?

Both are 240-position DDR3 DIMM sockets in the same 78373 series. The primary difference is the mounting angle: the 78373-0001 uses a 25° angle mount, while the 78373-0002 typically uses a different orientation (often vertical or another angle). Check the specific order code for your board's mechanical clearance requirements.
