[Elecraft] K2 control board question

[William Koucky]

I finished the control board and it looks good.  I didn't like how the
revised cap and resister went on the back side but otherwise it looks good.
I did have a question.  The IC #1 that I received was slightly different
than specified.  It is the only one left so I am assuming it is okay.  I
wanted confirmation before I solder, however.  It is called for NE 602 and
the IC I have is SA 612 C101708 Fn 344B.  Is this okay to solder?

Thanks for all the help.
