Shopping for Caps and this doesn't look right.

[softviruses2]

New to shopping for caps. Looking to replace these 8200 50v caps on an old Onkyo with one of the following https://www.digikey.com/en/products/detail/nichicon/LKG1H822MESBAK/7698791 or https://www.digikey.com/en/products/detail/cornell-dubilier-knowles/380LX822M050J452/1699765

but the lifespan on these seem really low? It says 1000 hours and 3000 hours for the Cornell caps. i feel like I'd put that kind of usage on them in a matter of months. Am i overthinking it or would these be fine?

you have to read the test conditions in the data sheets.

As @painttoad said, these are relative comparisons bases on specific test conditions and measurements. It’s highly likely that the original caps in your Onkyo would not even meet the standard for 1000 hour caps.

Look on this as an opportunity to understand caps better. Visit the manufacturer’s website and find out what 1000 and 3000 hour caps mean. Do the same for a few other caps. That’s how you become an old hand.

What type of audio unit are they for and in what section will they go into?

Haven't tested them yet. They're likely fine I'm just replacing them while I'm in there because I saw a bloated cap not far from it.

Amplifier with a goofy left channel that comes and goes. I'm sure its bad caps because I spotted a few bad ones on the board.

Maybe. Maybe not.

If it was me. I would t-shoot the problem first. My 2 cents.

Eliminate the possibility of an intermittent switch path. (dirty switch)

Could also be a cold/cracked solder connection in the left channel control amp(pre-amp) or power-amp. If your source was the AM/FM tuner. Then add the tuner to the list.

Your 2 cents is usually worth at least a quarter.
