That device is discontinued.

What is the actual problem you're trying to solve? If you want to know whether you can use it to replace the LM393M, then this is probably possible (the electrical characteristics appear to be the same). The only difference is likely to be in the packaging.

Hello Leo,

  While I do not have a definitive answer to what the NAK suffix actually means, it is most likely to do with the package compound.  We did find a reference to NAK as an alkali compound, and was a precursor to the NOPB packaging.  This is from the late 1990s, and a review of several 1997 datasheets does not shed any information on this suffix.

Hello Leo,

/NAK is a custom device, and it was obsoleted in 2015.

The closest replacement is the LM393M/NOPB

Thank you.
