Genuine Dell OEM Ribbon Cable YK41H

This genuine Dell OEM ribbon cable connects the palmrest USH junction board to the motherboard in compatible Latitude laptops. It is a direct replacement part for service or repair work. The cable carries part number YK41H and alternate references CAZ20 and NBX00023A00.

Installation notes for the junction board cable

The ribbon plugs into a low-profile connector on the palmrest assembly and routes to the mainboard socket. Carefully align the contacts before seating to avoid bent pins. Technicians should disconnect the battery before starting and handle the flexible circuit by its edges to prevent contamination.

Compatibility limited to Latitude 7480 and 7490

This cable fits only the Dell Latitude 7480 and Latitude 7490 models listed in the manufacturer highlights. It will not work in other Latitude series or in laptops from different manufacturers. Buyers who need a cable for a different model or a different internal connector should source the correct part number for that device.

Questions about this item

How can I confirm the ribbon cable is working after installation?

Power on the Latitude 7480 or 7490 and verify that the palmrest-mounted USH junction board functions, such as the fingerprint reader or smart-card slot, without error messages.

What is included in the box and what must be purchased separately?

The package contains only the genuine Dell OEM ribbon cable with part number YK41H; the palmrest junction board and motherboard connectors are not included and must be sourced separately if needed.

Which part number should I choose for a Latitude 7480 versus a 7490?

Both models use the same YK41H cable, which also cross-references to alternate numbers CAZ20 and NBX00023A00, so a single version fits either laptop.
