Macron MI1210CLE-R is similar to VTL5C1. 1,0-2,0K, Off resistance > 50 Megohms. Will also work as a substitute for VTL5C9 if you give it more drive current. May be used as substitute fot VTL5C6 with minimal trimming of other components.
These are used extensively in audio compressors, audio level controls, limiters, expanders, noise gates, tremolo effects, guitar amplifiers etc. 400R ON resistance.
The Opto-switcher module pre-soldered assembly can be used or any application where you need a 6v directly driven photocell based optocoupler. This can be used as a 6v version of the Fender style optoisolator and uses the same photocell.
