Genuine Dell OEM ribbon cable 8N12V

This is a genuine Dell OEM ribbon cable with part number 8N12V. It connects the USB and audio I/O board to the motherboard inside compatible laptops. The cable is designed specifically for Inspiron 14 models 3451 and 3452. You receive exactly the part shown in the product images.

For Inspiron 14 3451 and 3452 repairs

This part suits owners of Dell Inspiron 14 3451 or 3452 laptops who need to replace a damaged I/O board ribbon cable. It is not for users of other Dell models or different laptop brands. Buyers who need a complete I/O board assembly rather than just the cable should look elsewhere. Technicians repairing unrelated chassis will find this incompatible.

Part number 8N12V confirms fit

The decisive specification is the Dell part number 8N12V, also listed as 450.03V04.1001 or IRIS14 IO BD. Matching this number to your service manual or existing cable ensures the correct connector pitch and length. No other dimension or feature determines compatibility.
