I’ve got some Fairchild 2KBP06M rectifiers that have the KBPM package style. However, this seems to be missing from the rectifier.lbr in Eagle. Is this a standard package type that is missing from the library or can I use a similar package without any problems?
What Leon said. Have a go at making it yourself. once you make a few things yourself, you will find that you will be making new packages for everything, just to be sure. The EAGLE packages are not to be trusted.
You can create a part in the time it takes to have a look on google
