Looks like the right place, welcome to the club. I don't know of such a part, but when I asked my friend Ms google (which is always a good first choice when you don't know something) with the search string
fritzing part RMD6300
among other not so useful results she returned
down in which (in Fritzing libraries) is a purported (because I didn't download it to see whats in it) library
which I assume will have the part. There are many parts that haven't made it in to the core libraries
available in various places (many on github). Google will usually find them.
