    Is there a rule of thumb for substitution of resistors if you don't have one available?

    For instance.... let's say you need a 82K resistor... what would be an acceptable substitution?

    Thanks from a new guy.

    That all depends on the application, maybe 10k, maybe 100k or maybe 82.000k
    82k is a standard value in the E12 series, so you should be able to find one. It will need to have adequate pwer and voltage rating.

    There is no rule of thumb because as duke37 said, it depends on the application. Note there are programs that can help you make up a resistance you need from other resistors you may have on hand. If you can build a C++ program, there's one in here (get the file). It also calculates voltage dividers for you.
