When searching for JST connector contacts such as SSH-003T-P0.2, you may find the device with an unexpected ‘H’ suffix like SSH-003T-P0.2-H. What does this ‘H’ indicate, and are the two interchangeable.
The ‘H’ indicates a High Pressure contact, which provides better retention of the mating pin contact and reduces deformation of the crimp from tooling issues. The two are largely interchangeable, but you may need to adjust your assembly process when switching from one to the other.
