I ordered a replacement 220V 1400uF 105degC capacitor (my only option with those specs) to replace a bulging one in my plasma TV. The one on the TV is somewhat shorter, but more importantly, now that I have it removed I can see it uses normal lead style connectors. The replacement (mfg part# EKLA221LIN142KA45M) has what looks like wider spade connections with a half circle in them.
There was another option (mfg part# ERLA221LIN142KA45M), but has a rating of only 85degC.
The really odd part is they both say picture is not indicative of actual product and both say Through Hole/Radial Can Snap In. The one I got is a picture of a real cap with the half circle spade, but the other’s picture is a generic 3D render with simple component leads.
Is there a drop in replacement for the one I removed, or will I have to get creative and cut up the spades?
In the pictures below the short one is the old unit to be replaced.
Welcome to the TechForum, max4677! The parts you ordered are technically through hole snap-in, they just have a different terminal design. There is more than one kind of “snap-in” design. One issue is it wouldn’t line up in the same way as the original, even if you “cut the terminals down.” ERLA221LIN142KA45M is not in stock and requires a minimum order of 200. The only items we have in stock have this other terminal design, unfortunately. What you could do is try soldering wires directly to the terminals and make them as short as possible. This isn’t going to be as secure and won’t look as nice.
Ok. Is there something I can use to help secure the replacement capacitor to the board? The board will be mounted vertically in the TV. The only stuff I have on hand that may work would be hot glue. The original installation relied on the soldered connections only. Perhaps I can lay the cap on the board, glue it in place, and then attach jumper wires as suggested?
You can certainly secure the cap using some kind of adhesive. I’m not sure if hot glue would be the best if it does get quite hot in the TV housing, though. The one downside is that the solution might make it more permanent and hard to ever fix again. Potting compound might be better: click here. I’m not sure if there is a way to “temporarily” secure it.
