Genuine Dell OEM Ribbon Cable for Inspiron 3551

This is a genuine Dell OEM ribbon cable designed for the Inspiron 3551 laptop. It connects the USB and audio input-output board directly to the motherboard. The part arrives new and matches the component shown in the product imagery. It carries the Dell part number V9V87 for accurate identification.

Replaces a Damaged or Faulty Internal Connection

This cable replaces the original ribbon link when it becomes torn, pinched or electrically open. A replacement is worth it when the laptop loses USB ports, audio jacks or both because the flex circuit has failed. Swapping the cable restores the board-to-board signal path without replacing the entire I/O daughter board. The alternate references 450.03005.1001 and IRIS15 IO BD BTM confirm cross-compatibility.

Suits Technicians Repairing an Inspiron 3551

The part suits repair technicians and experienced owners servicing an Inspiron 15 3551 chassis. It is not for buyers who need a complete I/O board assembly, a different laptop model, or an external peripheral cable. The component is a single internal flex ribbon with no additional brackets, screws or daughter boards included.

Questions about this item

Will this ribbon cable fit inside the Inspiron 15 3551 chassis without modification?

Yes, the V9V87 cable is a genuine Dell OEM part made for the Inspiron 15 3551 and matches the original routing and connector positions.

What is the correct way to seat the connectors on the USB audio board and motherboard?

Align each end with its socket, press straight down until the latch clicks, and avoid angling the plug which can bend the delicate pins.

When should this cable be replaced instead of reseated?

Replace the cable if the ribbon shows creases, torn conductors, or corroded contacts; otherwise a firm reseat often restores the USB and audio ports.
