- Yes, it would be okay to substitute P6202. You are also correct in
- noting that the 10V model would be too large and the axial model would
- be a bitch to mount.

-
- This is a typo in the parts list. The part number should be Q2102,
- which, in fact, is a 1K x 3 isolated part, not 1K x 2 as the sales rep
- thought (weird numbering at work here).
-
- I'll fix the typo now.

-
- Another typo, which I was notified of and fixed a couple weeks ago
- (i.e., if you had retrieved the doc's in the last two weeks this would
- have been fixed already).
-
- The correct number, as you deduced, is "EG1903-ND".

-
- Digikey carries the LM2931Z-5.0 part, as indicated in the parts list.
-
- Digikey *does not* carry the L293D. What's wrong with Active? I've
- never had any problems with them, at least the Massachusetts office.
- Also try calling Arrow for this part.
-
- Sorry for the typo's, thanks for reporting them.
