Replacement Capacitor for Board of Education?

Hello Everybody I was wondering if the 6.3v 1000uF Capacitor that parallax sells could be used to replace one of the 10v 1000uF Capacitors that's on the Board of Education?

    Yes. Both such capacitors are used to filter the output of a 5V voltage regulator and the 6.3V rating is high enough for use at 5V. The major issue is size / lead placement ... If it fits, you can use it.

    It's generally a good idea to have a larger safety margin than 1.3V, though, which is why the original capacitor had a 10 V rating.

    True Leon. On the other hand, a 6.3V part will have some margin. It won't magically blow up if you apply 6.93V (+10%). It may have a shortened working life though (spec'd at 3000h with Panasonic SMT 6.3V electrolytics)

    Thanks Mike and Leon, that makes finding one easy I need a new 3.3v voltage regulator anyways.
