As I mentioned a few weeks ago I had been hunting for replacement FFC cables for the T102 KB and LCD. Ones of the correct length and pitch are available from Mouser, but the MOQ was 1,000 pieces! After a lot more searching, I found some I could get in smaller quantities. The original cables have an extra strip of 1/8" (3mm) plastic stuck to the back side of each end to make it thick enough for the connector. After some more searching I found some self-adhesive UMHW tape and painstakingly applied it to both ends of each new cable, so they are direct replacement for the original.
Of course, the problem still remains that sometimes the connectors themselves go bad and are much too tight and can damage a cable (new or old). I'll be testing some replacement connectors in the near future. The link to the cables on my website: https://www.soigeneris.com/flat-flex-cables-ffc-for-t102 Jeff Birt (Hey Birt!)
