I received an email from JLCPCB, however I am not seeing how it could be a substitute:

Hi sir ,

Thanks for your email, my colleagues applied to purchase it for several times recently , but been rejected by purcahsing department because of high cost and supply resource shortage , so we do not know when will it be restocked , very sorry .

I tried to find another item C14909 which has the similar description with ATTINY841-SSU, please take some time to check it , thanks !

Wish you all the best


Just search Aliexpress for 4000006013780 or 4001154244711
