Part-identification

I’m having issues identifying this parts.
C02C and 02B is this same chip, probably different manufacturer.
02b has a slightly larger case size.
Has anyone come across these chips anywhere and can tell what they are?
I will be grateful for help.

C02C

02B

Hello,

Thank you for your post.

I am not having any luck so far with identifying those chips.

If you would happen to have any further information, we could try some other resources.
