DELL Latitude 3120 2-in-1 11.6" Touchscreen LCD Ribbon Cable T0431

Genuine Dell OEM replacement part

This ribbon cable is a genuine Dell OEM component designed specifically for the Latitude 3120 2-in-1 system. It serves as a direct replacement for a damaged or faulty display connection. The part carries the Dell part number T0431 and alternate references GDB10_EDP_CABLE and DC02003RJ00. It is intended for repair technicians or owners restoring screen functionality.

Model-specific compatibility constraint

This cable is validated only for the 2-in-1 variant of the Latitude 3120 and will not fit the standard laptop version. The distinction is critical because the convertible hinge design requires a different cable routing and connector layout. Installing this part in a non-2-in-1 chassis will result in a physical mismatch. Buyers must verify their exact model before purchase to avoid ordering the incorrect item.

Delicate flex-circuit construction

The flat ribbon design uses a flexible printed circuit that threads through the device hinge, making careful handling essential during installation. Sharp bends or excessive force can fracture the internal traces and cause intermittent display faults. The connectors at each end are low-profile and keyed to the motherboard and panel sockets, ensuring a secure fit when aligned correctly. Proper cable routing within the chassis prevents pinching during repeated 2-in-1 mode transitions.
