I'm new to trying to obtain obscure components, like this one: http://www.maximintegrated.com/datasheet/index.mvp/id/1762/t/or
This is pretty business oriented, so I hesitate. Can someone help me be sure not to mess this up so I don't waste anyones time (including my own)? I'm 17 years old. This component is important to my project, or a similar one, though I can't seem to find a replacement.

 

I'd just call them or send them a note. Be upfront about what you want and why. They might steer you to a distributor or, if you're humble and nice about it, they might offer to send you a sample.

 

Looks like it is in stock at Mouser.
