ginji Posted June 23, 2004 Report Share Posted June 23, 2004 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?

MP Posted June 24, 2004 Report Share Posted June 24, 2004 Here is a data sheet for the obsolete part. Perhaps you can match it to something that is available to you.MPTIL197-198-199_Opto-Isolator.pdf Quote Link to comment Share on other sites More sharing options...
ginji Posted June 24, 2004 Author Report Share Posted June 24, 2004 Ante: It's there so i don't fry the mother board of my computer and everything else with it if it stuffs upMP: 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 :) Quote Link to comment Share on other sites More sharing options...
ante Posted June 24, 2004 Report Share Posted June 24, 2004 Ginji,Are you sure it is broken? This is a component that does not break down under normal conditions. Ante Quote Link to comment Share on other sites More sharing options...
MP Posted June 24, 2004 Report Share Posted June 24, 2004 Can you get NTE parts? 4N32 is replaced with NTE3083.MP Quote Link to comment Share on other sites More sharing options...
ginji Posted June 25, 2004 Author Report Share Posted June 25, 2004 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 Quote Link to comment Share on other sites More sharing options...
ante Posted June 25, 2004 Report Share Posted June 25, 2004 ginji,If it is external and for protection of your computer you can use almost any opto with the right voltage. Ante ::) Quote Link to comment Share on other sites More sharing options...
MP Posted June 27, 2004 Report Share Posted June 27, 2004 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".MP Quote Link to comment Share on other sites More sharing options...
