Assuming I'm converting correctly (unfortunatly usually not a good bet though 
) 1.5 mm on the long side which should be 0.059 and the hole in the part is .052. If you have a jack and a vernier caliper, measuring a pin both ways would be a good bet. It is easy to boost the size of the hole a bit in the new part if we need to before boards are made. The mounting holes agree with the data sheet at .0472 (or 1.2mm) so its possible the pin holes are too small. Also even though they aren't connected, the data sheet shows the 2 pins I removed as being present (which could be a problem if they are there on your parts).
