A little update. I replaced the Teccor chip Q979 with a Q4025J6, the chips were dimensionally the same, and the dimmer panel now appears to be working fine.

I think I am going to try to get one of these, and see if it works. http://www.mouser.com/Search/ProductDetail.aspx?R=Q4025J6virtualkey57610000virtualkey576-Q4025J6 It at least looks like the old one. I am kind of guessing on every thing else. The dimmer circuit is fed by a 20 amp breaker and the dimmer board has a 15 amp fuse, and the voltage is 120v AC. I think I would have rather tried the Q2025J6 but it isn't stocked and had a minimum order of 125pcs. Think I am making the right choice? ----- Original Message ----- From: "andy pugh" <[email protected]> To: "Enhanced Machine Controller (EMC)" <[email protected]> Sent: Wednesday, August 14, 2013 7:25:38 AM Subject: Re: [Emc-users] Help IDing this chip (off topic) On 14 August 2013 12:24, andy pugh <[email protected]> wrote: > On 14 August 2013 12:18, andy pugh <[email protected]> wrote: > >> http://www.littelfuse.com/data/en/Data_Sheets/E4AlternistorTriac.pdf > > I guess it makes sense to go for the biggest? > http://www.digikey.com/product-detail/en/Q4040K7TP/Q4040K7TP-ND/216027 > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite!
