Using perl (untested):
$> perl -p -i -e "s/0603C/CAPC0603N/g;"  *

The above command will replace 0603C with CAPC0603N in all files (due to
"*") in the current directory.

If you want to be a bit safe, use:
$> perl -p -i.backup -e "s/0603C/CAPC0603N/g;"  *

This will do the same, but the original version of the files will be
saved in the original filename but with ".backup" added to it. If the
replacements are good, you can remove all *.backup files in the directory.

Regards.
