Looking for specs on a 2B104M ECQ-UH .G. Film Capacitor, need a replacement
Hello hhcorrea24,
Welcome to the TechForum.
I think what you have is a Panasonic based on the ECQ-UH.G., however I am unable to find any information on this part. Do you have a schematic or any other drawings that might give some insight to the other parameters of this capacitor?
Can you send a few images of the part? This might help in identifying and finding an alternate.
The below link shows what I had found. To help narrow further can you measure the lead spacing center to center? Also can we get an image of the other side of either of the caps you have?
That helps. It’s a Panasonic (their logo is the triangle with the arrows at each corner), 0.1uF cap, probably 20% tolerance, with UL and CSA markings, and we have a rough idea of the the size.
Are there any markings on the other side, and if so, can you provide an image of that as well? This may well be a “safety” capacitor, so seeing all of those markings are very important to getting the right part.
Also, I see that this board is marked as a Yamaha product. Which product is it? One might possibly be able to find more info based on that.
No markings on opposite side will send manual later today
Manual Attached the board is American Model VA81390 parts C4 and C1 Page 16

Hector

by looking at the data sheets on page 25 and 26 these look to be either 125V or 250 V and 0.1uf below is a link for what we have to offer for that value and voltages , I do not see that we have the cap that is in the circuit though . See if any of these will work for you there are several different sizes .
Agreeing with @Craig_2048, the cap in that schematic for the US, Canadian, and Japanese versions use a 125Vac rating, though a 250Vac version will work just fine.
Since they are connected from line to neutral, as seen in the schematic,
it should use an “X” type safety capacitor. Here’s a link to parts that meet that requirement.
Among those parts, I’d narrow it down to those with similar lead spacing, and then by the body size which fits within your physical space limits.
