I desperately need these three items for a project, but I'm having a hard time finding them. I had hoped to order all from a single source to save shipping costs, but I don't know if that's feasible. A cross reference with same pinouts might be helpful, but even having trouble with that... and running short on time. Any parts source and/or good cross reference would be welcomed. Thank you.
