RC4558 VS NJM4558 IC


New member
Just a quick question. Am I'm correct that the difference in the RC4558 VS NJM4558 IC is just the manufacture? RC

A rule of thumb that usually applies: The prefix indicates manufacturer and the suffix indicates a package type. Be sure to check datasheets to be absolutely sure, though. For example, with the LM386, the LM386N-1, LM386N-3, and LM386N-4 all have important differences in electrical specs. So it's not always the case that different suffices are functionally equivalent. With the TL072, though, the difference between the 'IP' and the 'CP' suffix comes down to operating temperature specifications and can largely be ignored for our purposes. Also, sometimes the suffix indicates how something is packaged (e.g., ammo pack, bulk, tape/reel).
