Questions relating to designing PCBs

Hi,

I've made a little board in Eagle using parts from the SFE and Adafruit libraries and I'm ordering parts from Digikey. I wan't to make sure I'm ordering the right parts.

On the BOM I have part C1:
Code: Select all
Part Value         Device                Package           Description
C1   10uF          CAP_POL1206           EIA3216           Capacitor Polarized  


and another 10uF capacitor:
Code: Select all
Part Value         Device                Package           Description
C6   10uF          CAP1206               1206              Capacitor   


Under "Device" both of the caps are 1206, but for package C6 is 1206 and C1 is EIA3216, which from my understanding means they're both the same, where 1206 is imperial and 3216 is metric. So could I buy this capacitor (http://www.digikey.com/product-detail/e ... ND/2103160) and use it for both C1 and C6?

Thanks for the help!

Nope..

The First cap is polarized, meaning it has to have a positive and a negative terminal. The linked cap is non-polarized.

Are these decoupling caps?
