Genuine Dell Touchpad Ribbon Cable J72C4

This genuine Dell OEM ribbon cable connects the touchpad module to the motherboard in compatible Inspiron and Vostro laptops. It replaces part number J72C4 and fits models including Inspiron 3510, 3511, 3515, 3520, 3535, 16 5640, and 16 5645. Buyers needing a different connector layout or length should verify their specific motherboard header before ordering.

Reliable Signal Transfer Under Daily Use

The flat flexible cable maintains consistent electrical contact between the touchpad and mainboard during extended typing and navigation sessions. Its construction resists signal degradation from repeated hinge movement and thermal cycles inside the chassis. No active components are present, so performance depends entirely on secure seating at both ends.

Straightforward Replacement With Careful Routing

Installation requires opening the laptop base, disconnecting the old cable from the touchpad and motherboard ZIF connectors, and threading the new cable along the original path. The main risk is creasing the flexible circuit or misaligning the connector tabs, which causes intermittent cursor behaviour. Technicians should avoid excessive force when locking the ZIF levers.

Questions about this item

Does the J72C4 ribbon cable draw extra power or generate heat during continuous use?

The cable is a passive flex connector; it carries only low-voltage touchpad signals and adds no measurable power draw or heat.

Which specific Dell laptop models must I already own for this J72C4 cable to fit?

It fits Inspiron 15 3510, 3511, 3515, 3520, 3535, 16 5640, 5645; Vostro 3510, 3520, 16 5640; Basic 16 DC16250, DC16251, DC16255, DC16256; Basic 15 DC15255; Pro 15 Essential PV15255.

Will the J72C4 cable work if I keep an older touchpad module from a different Dell series?

The cable is keyed to the motherboard connector on the listed models; an older touchpad with a different pin-out or connector pitch will not mate correctly.
