Genuine Dell OEM Replacement Ribbon Cable

This is a genuine Dell OEM ribbon cable designed for the Latitude 3420 laptop. It connects the right-side I/O board to the motherboard, carrying signals for USB, SD card reader, and audio ports. The part number is JW3G0, also referenced as 450.0NF06.0001. It is intended for technicians repairing a damaged or faulty connection on this specific model.

Build Quality and Connector Layout

The flat flexible cable uses the original Dell connector pitch and pin arrangement for a direct fit. Its routing matches the factory layout along the right side of the chassis, ensuring the SD, USB, and audio ports align correctly with the case openings. As a new OEM component, it arrives free of wear, creases, or connector oxidation that can affect signal integrity on used cables.

Compatibility Check Before Ordering

Verify that the service tag or model label confirms a Latitude 3420, as this cable is not interchangeable with other 14-inch Dell series. Inspect the motherboard and I/O board headers for physical damage before installation, since bent pins on either end will prevent a reliable connection. Have the correct disassembly tools ready to access the internal routing path beneath the keyboard deck.

Questions about this item

What interface does the JW3G0 ribbon cable carry for the SD, audio and USB ports?

The JW3G0 ribbon cable carries the signals for the SD card reader, audio jacks and USB ports between the right-side IO board and the motherboard in a Latitude 3420.

What physical space and connector does this cable need inside the Latitude 3420?

The cable fits the narrow channel along the right edge of the chassis and plugs into the ZIF connector on the IO board and the matching socket on the motherboard.

How is the JW3G0 cable installed and which step is often missed?

Open the ZIF locks on both ends, insert the cable with the gold contacts facing the correct direction, then close both locks; the step often missed is failing to fully seat the cable before locking the motherboard-side connector.
