Genuine Dell OEM Ribbon Cable

This is a genuine Dell OEM ribbon cable that connects the USB IO board to the motherboard in the Dell Inspiron 14z N411z laptop. It restores the link between the audio and USB ports and the main system board. The part number is NXK3J. Buyers who need a different laptop connector will not be served by this part.

Build Quality and Daily Use

The cable is a factory-original component supplied exactly as pictured. Its flexible flat design routes inside the chassis to carry signals from the side I/O board. No adapters or extra brackets are required for installation. Builders working on unrelated models cannot use this cable.

Replacement and Upgrade Context

This ribbon cable replaces a damaged or faulty original that has broken the connection to the USB and audio ports. Swapping it restores those ports without replacing the whole board. The change is worth it when the existing cable is physically torn or the connectors have failed. Users who need additional ports or a different interface will not gain them from this swap.

Questions about this item

What interface does the NXK3J ribbon cable use to connect the USB IO board to the motherboard?

The cable uses a proprietary flat-flex ribbon interface that carries USB and audio signals between the I/O board and the mainboard on the Inspiron 14z N411z.

What physical space is required to route the NXK3J cable inside the chassis?

The thin flexible strip fits the narrow routing channel along the palm-rest edge of the Inspiron 14z N411z and plugs directly into the board's ZIF connector.

How is the NXK3J ribbon cable installed, and which step is often missed?

Lift the ZIF connector latch, insert the cable gold-contacts-down until fully seated, then lock the latch down; forgetting to relock the latch causes intermittent USB and audio faults.
