Are manufacturer's allowed to put whatever code they like on devices ?
So is it possible to have 2 functionally different devices (on same
package?) with the same code ?


Did you look at the link? It happens, quite often. OEMs don't check
with each other to see if someone else is using the same code. They
don't care, because it is an internal product ID for their use, so
people loading pick & place machines can look at the marking and make
sure they have the right part. Its not THEIR problem if you buy parts
from someone else using the same code.

You have to have an idea what the part does, then look for parts
using that code that would do the job.
