Another DipTrace user here. Sorry I haven't contributed much on the more electronic topics that have come up recently. After using PADS PCB on a professional level for several years, a job change made me loose my ability to make any boards for myself, and on the reviews of DipTrace of those on this very board, I started using it to get back into board design on the hobbyist level.
Anyway, you might find what you're looking for in the "Con TB Wire to Board" library. It may not be an exact match, and you'll have to go through your spec sheets of the part you want to use and see if there's a part footprint that matches up, even if its not the right part number.
There's no foul in rolling your own part from scratch and adding it to your own personal library either. The DipTrace component and pattern editors are fairly intuitive after a little practice.
You also may find a similar part in a library that has the right footprint, and you could simply rename it and add it to your library.
