Hmm, don't know about this. They probably don't carry the 1381 though,
you'll most likely have to get it from DigiKey.

These are useful:
74**14 - Microcore
74**245 - Microcore
74**00 - Suneater 2,3
74**02 - Suneater 3
** = hc, als, hct, etc.... Soem are better than others, check the
schematics.
Info on the Suneaters series (They're great) can be found on Steven
Bolt's (He's cool) site:
http://www.xs4all.nl/~sbolt/e-index.html
It's on there somewhere....

From what I know, yes.

I only use calcuslator cells cause that's all I can get. They're great,
usually put out about 2.8 volts. I use FLED SE's because they trigger at
around 2.1v, but aren't as effecient as the 1381's. You can get 1381's
that will trigger at 2.1v, so yes, you can use your cells with a 1381
SE.
Adios,
