Charles,

Yes, the extra letters reffer to the case style and temperature range.
The LCN is a standard temperature range DIP package
the CCN is an extended remp range in DIP.
The LCD, I would expect to be a surface mount standard temp range device.

really?
a quick search with google showed a few places selling it.

can I suggest you try shopping around a little?
Plenty of places still sell the LF412CN.

> Anyways, Marc tells me that both components that I¹ve mentioned earlier
are

> database?

try search for 'LF412' or 412, same with the DAC, try 'DAC 0831' (with a
space) or just '0831'
