It was a standard D-sub connector at one point in time, DA19P is going to be the first part of the real part number. Only issue is that no one makes this one anymore as the D-sub is pretty much abandoned by the consumer electronics industry. Serial ports, single density 9 pin, and VGA, double density 15 pin, being the only survivors and even those have been almost entirely removed. Defense contractors still use lots of D-subs as it's a simple and cheap way to pass a bunch of signals. The major connector manufacturers stopped making 19 pins because no one was asking for it. Defense contractors aren't going to keep that model alive with their low volume orders, it's easier to just use a 15 or 25 pin D-sub. Since there are so many compatible drawings out there of D-subs, it's easy to find one that shows the breakdown of why the measurements are what they are. From there, you can easily backtrack and get the exact dimensions of a DA19P.
