optocoupler CNY17G-2

I'd try something common like a 4N35, there's loads of similar parts that should work fine. Is the base pin of the transistor connected to anything? Many optocouplers don't extend that out, if you don't need that, any of dozens of standard transistor output optocouplers should work.

That is the problem, The base is used which makes it harder to substitute. I was also told to be careful as this one is "vde" rated to specs and if it goes arse about I could be liable. I am also fairly new to the electronics industry after completing courses. Thanks

:Can anyone help with this component, it is used in a commercial cordless :battery charger and I can't locate any anywhere, I did try the internet but :they don't want to know me as I only want 1 or poss 2 as they not replying :to additional emails even after quoting me $5 each because of such a small :quantity.

I don't think there is anything special about the old or new version of the CNY17 - they all have the base connection brought out to pin 6. The 'G' suffix means that pins 1-3 are separated from pins 4-6 by 10.16mm rather than the normal 7.62mm. The '2' indicates the CTR which is 0.63 - 1.25 @ 10mA Ic.

There are other devices with the same pin spacing and isolation which would do the job, ie. CNX82A

Note that the Isocom version of the CNX82A does not connect the base lead to pin

6.

A search of the Farnell Australia site shows they have the Fairchild CNY17-2-M in stock at $0.55 + GST.

Note that the description gives the row pitch as 9mm which is close to the to nominal 0.4" (10.16mm) shown for the Vishay 'G' suffix.

Forget that. The 'M' suffix does NOT have the base lead brought to pin 6.

Who don't ?

It's an opto-isolator. Nothing unusual Simply substitute one with similar parameters.

Well, naturally,,, but it isn't quite that simple to find a suitable alternative to the CNY17-2G off-the-shelf. The main problem is nobody here stocks 6 pin DIP transistor output optocouplers with base connection having a 0.4" row pitch. Believe me, I have done a lot of searching.

I did find one possibility at WES Components. Their catalog shows the CNX82A which would be suitable provided that it is not manufactured by Isocom. The OP requires the base connection brought out and the Isocom version doesn't have that.

Looking at the specs I think the cnx83a will do the job, It does have the base pin connected as well, It is used in the circuit which made it more difficult. Also WES has the 83 there so will be easy to obtain, Thanks for the help.

Good. I hope WES have what you want. I also checked the Speedy Spares catalog and they list a CNX82 (no suffix thogh) so if WES can't help, try them.

alternative

Either of these close enough ?

I appreciate the trouble you have gone to to find these items, and yes, they would do the job. However, the Farnell Australia website (where the OP lives) doesn't have the same stock items as in the UK, and these 2 are not included. The Australian branch would probably order them in, but usually there is some requirement such as MOQ or shipping added.

I spent some considerable time on the Farnell AU website tring to determine whether or not any listed item was suitable and I have to say that their description and part numbering and the parameter selection table leaves a lot to be desired in trying to find a suitable item - I have complained to them on that.

For example, I challenge you to find from the complete CNY17 listing on the Farnell AU site

a simple and quick method of finding a locally available substitute for the OP's problem. Now if every DIL opto stock item had a suffix saying 300W or 400W this would help a lot, but they don't - only some do. And it is not stated in the stock item description either.

Thanks for the support about the farnell website, I thought it was just me or my inexperience that I had problems trying to understand it, even a phone call to their tech support gave no results, now armed with either those farnel items or the wes component I will have to get there to get the part and try it. Thanks again.

You can try Farnell to see if they can order in from the UK without additional expense. I confirmed that WES do have the CNX82A and it is QTC brand

QTC is now part of Fairchild but their latest opto catalogue doesn't show the CNX82A (or 83A) which I think were discontinued in 2004.
