2-HCPL 063N-000E

could i use 9814-2 and/or 9821-2 (each one replace 2 original with mod)?

hi fouad,
Welcome to AAC.
Checking the datasheets for the HCPL and 9814, an important difference is the maximum working voltage.
The 9814/21 appears to have a 5V limit and the HCPL is 30V.
As its a vehicle application, which may run at 12V or higher, I would say they are not equivalent types.
Check out the 6N135 option.

www.mouser.com has them. These were HP, then Avago and now Broadcom parts.
