More LF442 replacements: TL072 (low noise), TL062 (low power)
More LF444 replacements: TL064 (low power)
TL082 and TL084 are also options.

thanks Etaoin for the substitutes.

and thanks v-un-v for making this post "Sticky"

no probs dnny :)

I'm gonna address the other issues as soon as Mosc sorts out some current server problems.

What does "sticky" mean? Confused

i think that sticky means
the post will stick on top of the list no matter what.
so it will not get buried by time.

On the subject of substitutes I’ve been thinking about the 1N914 diode and whether it could be replaced by the 1N4148?

In the partslist for the 1V/Octave Voltage Controlled Oscillator the diodes are only refered to as High Speed Sw Diodes. Could the 1N4148 be used here as well? Confused

Uncle Krunkus · Posted: Mon Oct 31, 2005 1:21 am Post subject:

The 1N914 and the 1N4148 are almost exactly the same. I haven't come across a circuit which quotes one and doesn't work with the other. You can however get diodes that switch faster than either of them.

Does anyone know if the LM324 is a good substitute for LF444? Confused

I can't see anything wrong with it.
I'm not an expert at reading Op-Amp specs though.
Pinout, and power supply are fine, so I'd give it a go.

By the way, I'm currently building RJW's VCO and found that replacing the LF411 and LF442 with their TL "equivalents" doesn't always work. I can't get the 1V/Oct scaling right with these substitutes in. So the exact specs might be essential in some applications.

This might also affect the LF444 used in the SL's oscillators. I got mine to work with TL064's, but judging from my experience with the VCO, the original LF might have been better.

thanks for the info.
the "equivalents" are picked up whit only equal pinnouts . not by the specs Sad

I should probably add that my LF411 and 442 are still on order, so although I can't get the VCO to work properly with TL061 and TL062 replacements, I can't yet say it does work with the LF's! I'm just assuming that the reason I can't get it tuned is because I tried replacements. All other components are as specified and it does work fine apart from the tuning.

I was trying to explain that it was wrong to include my comment at the top of this thread. If I say that elsewhere, it's of not much use. I'd suggest just removing my messages from this thread.

Yeah,
Ray said there's some specific problem with the TLXXX series, I think it was in the VCO, can't remember, but apart from that they're fine.

Just a little warning.

You can't always substitute 13600 for 13700. 13700 have linearisation diodes, 13600 does not.

If Rays design uses these diodes you can NOT use the 13600 in stead of the 13700.

I do not know if this is the case though.
