Default DFI-ITOX G4S600-B with Chemicon KZGs - compatible caps?

Hey guys,

I've got a G4S600-B (this board) that has about 2 dozen UCC KZG caps on it. This is in a digital audio encoder used at a radio station, so it's been on/powered pretty much 24/7 for a number of years. recently it's been getting flaky, so I pulled it apart and noticed that 7 of the 16 1500uF caps on the board are bulged. Did some more research, (signed up for this board!) and find that the KZGs are pretty much despised here.

So I'm looking to recap the motherboard. The KZGs on it are all 6.3V, 105degrees:


1500uf 8x20mm marked 5(7) 7S- 10
1500uf 10x20mm marked 6(7) 6G - 4
1500uf ~10x12mm marked 6(k) 8E - 2
470uf ~5x11mm marked 5(k) 6c - 3
470uf ~5x11mm marked 5(k) 6V - 3

I'm assuming that I ought to replace the 470uf caps too?

(EDIT: looks like all the rest of the on-board caps are Nichicon HM(M) or OST RLG)

I'm looking through Digikey, most of what I'm seeing is Nichicon/Panasonics/Rubycon. I'm not very knowledgeable on ripple currents, esv, etc., so I'm hoping someone on here can help me out with some compatible replacements. Here's where I'm looking:


I've never seen a MB with this many popped caps!

Thanks guys,

-J
