  • Genuine Dell OEM part ensures exact fit for Latitude 7300
  • Connects palmrest USH junction board to motherboard reliably

  • Alternate part numbers EDC30 and NBX0002F900 confirm cross-reference accuracy
  • New condition guarantees unused, factory-quality ribbon cable

Genuine Dell OEM Ribbon Cable H0RXX

This is a genuine Dell OEM ribbon cable designed for the Latitude 7300 laptop. It connects the palmrest junction board to the motherboard, carrying signals for integrated palmrest functions such as a fingerprint reader or trackpad buttons. The part is supplied new and matches the component shown in the product images.

Replaces Damaged or Faulty Palmrest Flex Cable

Install this cable when the original flex has been torn, creased or corroded during a palmrest swap or liquid spill. The jump is worth it if the USH board no longer communicates with the system, causing missing biometric login or unresponsive touch controls. No other laptop models are supported by this specific part number.

Suits Technicians Repairing Latitude 7300 Units

This cable suits repair technicians and owners performing board-level maintenance on a Latitude 7300. Buyers who need a different length, pin-out or connector orientation for another chassis should look elsewhere, as this part is keyed exclusively to the 7300 palmrest junction layout.

Questions about this item

Does the H0RXX ribbon cable reach between the palmrest USH junction board and the motherboard in a Latitude 7300?

Yes, this genuine Dell OEM ribbon cable is designed to connect the palmrest junction board to the motherboard on the Latitude 7300.

How do I route the H0RXX cable during reassembly so it does not bind or pinch?

Lay the ribbon flat along the chassis channel, seat the ZIF connectors on both ends with the blue tabs fully closed, and verify the palmrest sits flush before tightening screws.

When should I plan to replace the H0RXX cable if the USH fingerprint reader starts failing intermittently?

Replace the cable if reseating both ends does not restore reliable fingerprint operation, as flex fatigue on the ribbon can cause intermittent USH signals.
