A funny thing happened with my MOC3041

[turdadactyl]

In my last parts order I included an MOC3041. I no doubt did this after seeing it in a circuit I found interesting. Of course now I have the part but no clue what circuit I saw it in. Anybody have any ideas on why I bought this?

Hmm, I wonder if I got this as a substitute for the MN3007 in the BBD section of the CE-2.  Sounds plausible, right?

This post wont be helpful, but I've done this numerous times. It's nerve wrecking, its like when you are trying to think of a movie and can't for the life of you remember what its called.

Well, it's a triac gate driver, used to opto-isolate a control signal from the AC-mains-hot terminals of a triac. It has internal logic and an internal baby triac that implements zero crossing detection and drive so that it only turns on the external conduction near the zero crossing of an AC wave.

I can't think of any place to use it in a pedal. Maybe useful for footpedal controlled stage lights or some such. I was thinking it might be used as an isolated signal shunt/cutoff device, but that would need a transistor output, not a triac output.

Probably a clerical error in ordering.

I thought it was only me! 

I try to keep my parts orders separate so what you're going through doesn't happen....anymore!

Mouser has a project manager that you can assign project names.

I still find myself placing parts for a project that I forgot to order or didn't know I was going to need, in another project's order.

Make notes!

Since I work out the details of many projects at once, I produce a BOM for every project so I can keep track of parts and add them to the appropriate project "box" of parts. I pencil in what supplier certain parts are coming from after I place the order.

If you mark them off of the BOM list when they arrive...you lesson the chance of double orders and/or not ordering what is needed.

RG, what do you think about the CE-2 theory in my second post, above?

[armdnrdy]

The only thing that would work in place of a BBD is....another BBD or a retrofit for a digital delay IC.

Are you working on any project that calls for a MC4013 (CD4013) dual flip flop?
I can see those numbers being transposed....and CD4013s are used in stompboxes.

This whole thread is like a living example of the situation itself.  Armdnrdy, transposed is right.  The part I have is MOC3041 not 4031 as I originally typed.

MOC3041 is still an opto-to-AC-power device. Not usable in pedals that I can think of.

The advice is correct - maybe you were trying to find a CD4013 dual flip-flop. I feel for you if that's true - the key with the most usage-wear on my keyboard is the backspace key. 

I think that character transposition is more likely than changing "MM3007" or similar BBD into MOC3041.

Just a guess.

Screw it!  I'm gonna just paint it up like a ladybug and keep as a pet.  I've wasted more on less.

The problem you have is that there does not exist any MC4013 (4031) or MOC 4013 (4031).

If you want to obtain a CD4013 from (Motorola)/ON Semiconductor then the correct part number is: MC14013B

If you wrote MOC 4031 then they took the nearest possible device and that would be indeed a MOC 3041.
