630G dimensions

I have been using the 530G and am getting the 630G next week. Are they both the same dimensions? I have a particular cell phone case that I have been using for years and hope I can continue to use it. The belt clips break too easily and I am a tad clumsy. With the clip, I tend to knock the pump on too many things and scratch it a lot.

The dimensions for the 630g

2.1”W x 3.78”H x 0.96”D
