[Elecraft] K2 U12 MC1350 or SMT1A

[John Shadle]

Hi,
I'm working on the assembly for S/N 5684. I don't appear to have the 
SMT1A replacement board for U12, but I have the DIP MC1350.

Should I request a replacement part for this non-RoHS part, or just go 
ahead and stuff this DIP?

I assume they perform the same function, but just wanted to make sure 
there isn't some other reason to replace the part with the SMT1A board.

Thanks.
