NE602, NE612, SA602, SA612 all virtually identical. NE/SA are different
manufacturers, 602/612 are different test specs. Generally the 612s are a
little cheaper. Same basic specs just tested less extensively.

Anyone know if these NTE7164 is a drop in replacement for NE602?
What are other current IC's being used for mixers by homebrewers?
