content: I've gathered that this is a 26 pin, 0.4mm pitch connector, but could use some help figuring out exactly which brand/model it is (there are quite a few different options and sizes on Digikey!). I believe this is one of the two touch bar connectors.Thanks!

content: Looks similar to Hirose DF40GB, however you should measure exact dimensions precisely and compare with datasheets. There are a lot of similarly looking connectors. It may be easier to buy a matching male/female pair of similar connectors and change both rather than finding an exact match.

content: Quote from: wraper on January 13, 2023, 06:25:45 pmThank you! I'll check the datasheet for that connector. I tried measuring but ended up with connectors that didn't match the footprint :-)

content: Quote from: mayor on January 13, 2023, 06:33:44 pmGood try on the Hirose, but unfortunately, there are no 0.4 mm 26-pin Hirose connectors. I'm kind of ruling that one one.

content: Alright, I've checked the series for every 0.4mm connector on Digikey, nothing seems to match. Maybe someone has had to replace these.... Help!

content: on the schematic of this macbook, the connector is annoted DF40SGwhich gives this Hirose part :https://www.hirose.com/en/product/p/CL0684-4224-2-51#

content: Quote from: kripton2035 on January 13, 2023, 08:05:09 pmThank you! Somehow, looks like no part on the Hirose site actually match (the one linked to is 10 positions). I could give the 30 position part a try I guess!

content: It's probably a special order part, not off the shelf stuff. Here it's listed as DF40PG(1.5)-26DS-04V(51) but looks the same.https://www.hklrf.com/DF40PG1526DS04V51_6285.html30 pin connector will not fit to male counterpart, not to say certain pins are connected to the shield.

content: yeah probably a special order part. apple is fan of it ... you may need a donor board.

content: Amazing, thank you all! I'm going to give replacing both plug and header with 30-position GB type. Never soldered on a flex cable, should be interesting.
