Hey guys! Hi!. I have a dod delay, that works on 9volts, that has a mn3101/mn3005 in it. I'm planning on building a fl301, and havea spare mn3102, can i just sub it?. Thanks  for your opinions.

Noooope, they are slightly different devices.  The 3102 is for MN32__ series, 3101 is for MN30___ series, AND their ground terminal is different.  And I"m not sure-but I believe their clock frequency generation is different a little bit.  50% sure on that one.
