darlington optocoupler

[ginji]

I'm after a part that is close to the 4n32 (Fairchild) or TIL198 (TI - obsolete) optocouplers... I can get parts from TI, maxim-dallas and national directly but not fairchild and the TIL198 is unavialable... does anyone have an suggestions for a replacement IC?

ginji,

What is the application?

Here is a data sheet for the obsolete part. Perhaps you can match it to something that is available to you.

Ante: It's there so i don't fry the mother board of my computer and everything else with it if it stuffs up

MP: I've looked at the datasheet and the 4n32 is the only part i have found that is close, otherwise i wouldn't be asking

Ginji,

Are you sure it is broken? This is a component that does not break down under normal conditions.

Can you get NTE parts? 4N32 is replaced with NTE3083.

Ante: I think you misunderstood me, i'm not trying to replace a part, rather get one to so i can use it as a precationary thing

MP: First i've heard of NTE, and looking on the distributor list only lists one in Queensland.... a good 600k's away from me at least, with no option of ordering over the net.

Thanks for your help guys, i may go try and figure out a non-darlington one

ginji,

If it is external and for protection of your computer you can use almost any opto with the right voltage.

ginji,
I also tried an e-mail to an engineer at TI, but he replied a few minutes ago that TI does not have a replacement for that part and he did not know where you would find one either. Looks like you might have to settle for "close".

thanks for the effort you put in guys

the closest part i can get is a 6n138 - http://www1.jaycar.com.au/products_uploaded/ZD1940.pdf

but i dunno if it's compatiable

Mouser and Digikey both have this IC in stock and by Many Manufactures

Here are my search results.

There you go, ginji. If anyone on this forum can find the data sheets and parts, it is John. ;D
