If I'm right that it's really 1.27mm, and 1.25mm is undersize, the
difference between 18x1.25 and 18x1.27 is so small that it still works.
Maybe a 40 or 50 pin wouldn't still work, but the error doesn't
accumulate enough within only 18 pins.
This is a great answer to this problem.

Perhaps217: I did some looking on this subject. The original display
FFC is 1.25mm pitch, 152mm long (measured with calipers).
I thought that was Molex part #15168-0375 , but I ended up buying
Molex part #15168-0379 (a 202 mm FFC) as the 152 mm version was not
available quantity 1.
That turned out to be a bit on the thin side, but worked fine once I
backed it with a bit of kapton tape.
Good luck!

Hello.
I’m looking to replace the 18-pin and 30-pin flat-flex-cables in my Model 102,
and was wondering if anyone can confirm the dot pitch. I did order some 1.0 mm
dot pitch from DigiKey which don’t appear to be correct - the FFCs are too
narrow:
686618152001
0982670475
If someone has the information to share, and perhaps even a known good source
that would be great.
Thanks, Alan
