rs-components do not have the 0.68!

Can I use this ATmega48PA-88PA-168PA-328P.pdf?

Here is what I have up to now:
the 100F tantalums are quite expensive!
The 100 uF is a aluminuml electrolyte in Kapteins design - much cheaper than tantals. Like this from RS (Number 193-6720):

0.68 uF: try searching for 680 nF instead. Some stores list them that way. RS here in DK has 680 nF 35V tantalums - item number 537-4413.

They also stock polyester film caps in 0.68 uF (680 nF)

I believe that the Kaptein said earlier that only C9 absolutely has to be a Tantalum!

IC looks good - be sure to get a 28-pin - RS listings can be hard to decipher...
