I am currently looking for a source of Darlingtons. The joys of supply chain.
Cheers and thanks for this thread.

Pretty much any NPN Darlington will work. Some may have different pinouts or package sizes.
There is a way to update the firmware on the controller to solve this problem
See this topic:
Thanks for your reply. I was able to find a "non lead free" version on Mouser. The more common versions were out of stock and their restock window was months out. I installed the fix and it seems to be working fine.

Thanks also for the link. There was some really good information therein. I was still not able to determine whether the firmware would work on a BBS02 or if there was a different firmware that would. The thrust of the thread was a voltage issue on the BBSHD and I am seeking a fix for the throttle issue on the BBS02. I discovered my older 02 bike has had the same problem and I don't want to tear it apart if I don't have to.

The firmware Tomblarom shared in ... 6#p1591048 fixed the PAS/throttle problem on three of my controllers, HW 1.5
My current bbshd controller is broken, no pedal assist anymore, throttle works perfect. Changed pas sensor, no Bueno.. Now I'm looking for a new bbshd controller, but which type nr should I buy in order to flash this firmware?

My current bbshd controller is a 1-80-502. (1.4) so I can't flash the Tomblarom firmware, because that's 1.5.

I'm looking to buy: c769-51-501 controller, hopefully it's 1.5
