I was surprised to find how different and impossible it was to substitute one for the other. I decided to survey the mini Pixhawk field and see just how different the cabling is between them, compared to the Gold standard of the original Pixhawk designed by Lorenz Meier (Pixhawk.org).

The two can be interchanged but it is not a perfect fit. The last and most commonly used in the mini Pixhawk field is the JST-SH 1.0. It is noticeably smaller than the other two.
