Broken Trackpad Ribbon Cable Connector

Now I’m no microsoldering or logic board expert, I think you’re looking for a 48-pin trackpad connector (knowing how many pins you need definitely helps finding parts). The Apple product number for that part appears to be 516S1037 (or maybe also J4802) and the only seller I could find based on that information is https://beetstech.com/product/macbook-pr.... I have not heard of this company so obviously YMMV. Annoyingly, they don’t have product photos to confirm, but the listing looks good.

The generic name for this connector is DF40BG-48DP-0.4V and you could probably find more results with that search term elsewhere, maybe Aliexpress or the like?

Now operating under the assumption your MacBook is a 2014/2013 model, I can’t seem to find any available online. Apple specific parts at least.

If I were you I would go to Aliexpress and search for “18 pin FFC connector”, there’s going to be a bunch of generic options. It’s just a generic FFC cable and connector, so they should work. I don’t have the measurements on that connector at all (1mm? 0.5mm?) but you should be able to find a match.

Edit: And by measurements, I mean pitch:

Pitch

The spacing of the conductors. The pitch typically refers to the distance from the center of one conductor to the center of its neighboring conductor. A single FFC can have different pitches between different conductors on the same cable, however this is uncommon. FFC cables are available in many pitches, such as 0.500 mm, 0.625 mm, 0.635 mm, 0.800 mm, 1.00 mm, 1.25 mm, 1.27 mm, 2.00 mm, 2.54 mm, but the most common pitches are 0.500 mm and 1.00 mm.
