Genuine Dell OEM Replacement Part

This ribbon cable is a genuine Dell OEM component designed for the Latitude 3480 laptop. It connects the USB and SD IO board directly to the motherboard. The part number is J8J74, also referenced as 450.0A10D.0001. It arrives new and matches the exact specification shown in the product imagery.

Ideal for Latitude 3480 Board Repair

This cable suits technicians or owners repairing a faulty USB or SD card interface on a Dell Latitude 3480. It is not a universal cable and will not fit other laptop models or motherboard revisions. Buyers needing a different connector pitch, length, or pinout for another device must source the correct part for that specific hardware.

Installs Inside the 3480 Chassis

The ribbon routes internally between the IO daughterboard and the main system board within the Latitude 3480 chassis. Replacing a damaged cable restores peripheral connectivity without replacing the entire IO board. No external adapters or additional cables are required for the connection once the part is seated correctly.
