Alex Tsekenis Posted December 16, 2009 Report Share Posted December 16, 2009 It is so annoying, these Chinese-made devices with non-standard part numbers.Anyway, apparently the PCR606 is a thyristor in a T0-92 package with the following key specs:V(DRM): : 400 vV(RRM) : 400 vIT(RMS) : 0.8 AI(GT) : V(AK)=7VMax IGT=200 uAV : 1.7 VTry this:http://uk.farnell.com/nxp/bt169d/thyristor-0-8a-400v-to-92/dp/1510734Regards,Alex Quote Link to comment Share on other sites More sharing options...

Hero999 Posted December 17, 2009 Report Share Posted December 17, 2009 Let me guess, it's a set of Christmas tree lights?Any TO-92 SCR with an adequate voltage rating will probably do but be careful with the pin-out. It might be a good idea to check the pin-out for the one that works before getting a replacement.I have some old Christmas tree lights I'm throwing way. I ripped open the controller and found four XL1225 SCRs which I'll desolder and test. The controller IC is marked SU168 which could be anything. It's a typical example of shoddy cheap Chinese construction and looks like a five year old put it together which is probably true. Quote Link to comment Share on other sites More sharing options...
Alex Tsekenis Posted December 17, 2009 Report Share Posted December 17, 2009 I am surprised that they put an expensive (for Chinese product standards) DIP package for the controller. Usually it's a COB. Quote Link to comment Share on other sites More sharing options...
hotwaterwizard Posted December 20, 2009 Report Share Posted December 20, 2009 Looks like Stuee lost interest in this post. Quote Link to comment Share on other sites More sharing options...
