Best Practice for Electronic components

Hi Experts,

I am working in a project in which we want start using suplier BOMs containing electronic components(such as a resistor).

These components will be bought from sub-suppliers so we have no need to create new vendors or PIRs.

I wonder if there is any best practice for creation of electronic components master data.

For example,

should resistors, capacitors etc be defined as Raw materials or Semi finished goods?

Any documentation or information is highly appreciated.

Kind Regards

Mikael
