Title: Help Identify Q in Air Pump
Post by: NivagSwerdna on September 23, 2023, 10:55:01 am

I thought maybe there was a topic for component identification but cannot find it so creating a new one...

Device in my air pump seems to have split its side so presuming this is the cause of my problem.  Air Pump for a pond... this seems to be part of the speed control.

Not sure how to read those numbers... Thanks in advance

OK looks like a Triac

I cannot find any of them but I can source MAC97A8.  Does that sound like a reasonable swap?

I was reading mine as a 6... maybe it is an 8?

As far as I read it, it is a MAC97A8, so it sounds like the correct part. Be careful if it is connected to the mains. It also looks like there might be signs of corrosion, check the resistors also.

 MAC97 - sensitive gate triac. The other letters tell you where and when it was made, etc..
