Thanks Pete,
I'll order the first one you listed.
Now to find the tatalum caps to make keep alive
You're welcome!
As for Digikey website, once you learn how to use the filters to narrow down searches, it is not very difficult or overwhelming.
Go to the capacitors/tantalum section then select "active", "in stock", "bulk" and "cut tape", "operating voltage" (I recommend 25V), "capacitance", "surface mount". You can select ranges of values by using shift key. Then click "apply all". When you get results, you can now select the size (dimensions), as the size selection range will be narrower.
I also recommend looking at Mouser Electronincs site. Search filtering process is similar to Digikey. You migth find something Digikey does not stock, or cheaper prices for similar part.
