Fitting modern snap-in capacitors into older snap-in through-hole placement

[brandon.arnold]

Hi all. I'm looking to replace this large capacitor (labeled C627), in the two photos. Looking at the modern equivalent cap datasheets, there are a couple of snap-in mounting types. See the screenshot below, showing both. The old one I'm replacing is the "LI" type on the right.

I don't actually think anyone makes this pin placement anymore! So I've already got the left-most "VS" types on the way.

Has anyone done this retrofit before? I would love advice on how to stabilize it. The best I've got right now is to bend the pin and hope for the best. Maybe hot glue.

Hot melt glue does not always stick to everything.

Silicone sealant pretty much sticks well to everything.

That is a high quality capacitor that typically outlasts many others. Are you sure you need to replace it?
You can find snap-ins that match the diagonal pin spacing i.e. 10 or 15mm and fit that in, the cap ends up likely rotated a bit.

Thanks for the tip! I will consider that. Does seem like something I would regret when I'm 60, replacing these again.

The snap-ins I have ordered should fit, in that case!

I am having wobbliness on my monitor at high brightness levels that leads me to suspect this large capacitor (see around 0:17 before the end of the video below. I've had the other caps replaced and the flyback on this monitor is impossible to find.

Do you have any tool or access to one that can test capacitance or ESR?

Its very rare that a main high voltage capacitor fails, usually its the lower voltage output capacitors or bootstrap cap. But you've replaced those and it had no effect? I don't see them in the photo, all of the small caps in the photo look to be original.

Interesting. I actually had them re-capped by a Sony tech who is known in the retro tech scene. He does not replace all caps, but ones he deems most prone to failure. I would not be surprised if other caps need replacing.

Edit: And yes, I do have a capacitor / ESR tester. But I assume it would not be able to test the kind of load these big boys require?

If you have an ESR tester then you could test all the caps yourself.
Look up on a chart or in a datasheet if the ESR is reasonable. For that 450V 330uF ESR spec is 0.75R (?), not sure of the exact number, but I would expect under 0.5 ohm if its still good.
