4n25 vs. 4n33

Hi guys

can I use a 4n33 optoisolator instead of the 4n25?

Mainly because I DO have a 4n33 and I dont have a 4n25

Thanks in advance guys!

I SUCK AT ELECTRONICS.

I would look at the datasheet for each opto isolator. They are not of the same family but Upon my first looks it will operate the same.

4n33 http://www.datasheetcatalog.com/data...3/3/4N33.shtml
