Does cap physical size matter????

[max2004]

Hey all,

Received my new caps from badcaps.net the other day.
They're a bit shorter than the old ones.
Diameter is the same.
Will they work just the same??
Thanks

Re: Does cap physical size matter????

The replacements will work fine. Physical size will affect ratings ( ESR, Ripple ) within a series. It looks like an HN 10X16mm but Nichicon also makes that size in HZ.

KZG 6.3v 2200uF 10X20mm
ESR 13 Ripple 2550

HN 6.3v 2200uF 10X16mm
ESR 11 Ripple 2200

HZ 6.3v 2200uF 10X16mm
ESR 10 Ripple 2960

Re: Does cap physical size matter????

These pups are needed on a ibm motherboard right beside the CPU.
There's 5 of them in a row.
I see these new nichicon caps say hn(m) on them.

Just reading on another thread here, someone says to replace
all nichicon hn(m) caps, busted or not???

Is this still OK?
Thanks

Re: Does cap physical size matter????

Looks like you bought the HN.

You should have bought the 20mm.

Re: Does cap physical size matter????

with HN/HM:

the datecode is the magic number here

example:

H0306

H- start letter. may also be an A

03- the year of production

06- the week of production

with HM/HN, if the year is 01,02,03, or 04, they need to go. 05 caps are it and miss, 06 and later are A-OK. the above example was pulled from a blown HM, btw.

GGGGRRRRRRRRRR!!!!!!!!!

Should have asked you all 1st . . .
Guess I could always put these in the fire and watch 'em pop lol.

Anyways, I'll ask now.
What is the best replacement cap for these?

KZG 6.3v 2200uF

(M)105 0c
4(7)
1L


Rubycon perhaps??

Thanks very much.

You're missing the point of his post.

He bought *NEW* HN from Topcat, but he got the short ones which don't have enough ripple suppression.

This will do fine:
https://www.badcaps.net/store/produc...products_id=32
Around a dollar a piece.

These are just as good if not better, and are cheaper:
https://www.badcaps.net/store/produc...roducts_id=137

Keep in mind that the first link I posted are 25mm capacitors, but judging from your picture, I don't see them interfering with the heatsink. If you want strictly 20mm ones, get the ones from the second link.

You should also replace those 10V 1500uF caps:

In fact, ALL those brown caps that say "KZG" on them on your motherboard should be replaced. Whether they have bulged or not.


Topcat:
You should get some more 6.3 2200uF Nichicon/Samxon/Rubycon in stock.

and you missed my point. I was explaining what he read:

Do you have anything to back this up? I've used tons of these HNs and in my experience 2280 will be more than enough ripple.

When replacing a capacitor, you always want the same or better specs compared to the original. Will a lesser rated cap work? Maybe, for a while, but it may have long-term reliability issues. Were the original caps overkill and a lesser rated cap will suffice? Maybe. Throw in a marginal power supply and all bets are off.

The small HN has inferior specs compared to the original KZG. The original KZG capacitor is rated for more ripple than the HN he wants to use as a replacement. The larger size HN will work fine and has superior specs to the original KZG.

Should be fine.
The polymer caps around the CPU do most of the filtering. The original design likely included the KZG caps just to increase the bulk capacitance of the VRM (since there is also a certain capacitance needed in the VRM).

In any case, try the Nichicon HN and run Primer95 or some other benchmarking tool for a few hours (or a day). If computer is stable, just leave them alone.

As for Nichicon HM and HN series, those had a problem between the years of 2001 and 2004. After that, Nichicon fixed the problem so they are fine now. ratdude already showed how to read the date code, but if you got these from badcaps.net, then they are new and you have nothing to worry about.

Re: Does cap physical size matter????

They will work fine... As for who asked about more of a 2200uF 6.3v variety, I am getting some 2200uF 6.3v HM series to go along with my HN and HZ series.

Re: Does cap physical size matter????

I'm looking to replace a load of 3300uF caps on a DFI LanParty UT NF3 250 and an MSI Socket 939 board, will Nichicon UVR0J332MPD1TD caps be fine? I think the package is right (10mm radial leaded), but I can't find any ESR data. And not sure what value range of ESR is suitable anyway, really...

Re: Does cap physical size matter????

No, VR is absolutely NOT a suitable replacement...

You want something like this:

HZ is a bit overkill, but that's the only thing Topcat has in stock for 3300uF... Make sure the voltage matches.
