Original Xbox Replacement Caps

Re: Original Xbox Replacement Caps

Hello,

Well after 20+ years my orig Xbox 1.0 finally started to Frag a couple of days ago.
The 4 Caps near the Cpu are leaking from the top. (the right most cap isn't)
The clock cap leaked all over the board too.
I removed the clock one and cleaned up the MB using 91% rubbing alcohol with Q-tips.

I couple of questions:
Where do I buy the Cpu replacement caps? Links please. (I'm in NH, USA)
Is a 15watt iron ok? That's what I used to remove the clock cap.
I also have a 45watt de-soldering red bulb (radio shack) iron too, is that ok to clean the holes of solder? (I didn't use it yet)

The pic shows the cpu caps, I removed the orange stuff leaking from the top to see the writing on them.

Thank-you, Michael

You may struggle with a 15w iron, especially when trying to clear the holes. You may have to use the wiggle in and out method heating the two holes off and on.

Re: Original Xbox Replacement Caps

you have no chance with 15w
a 40w iron is still difficult.
you may be able to do it with a 25w iron by clearing the holes with a stainless-steel needle

Re: Original Xbox Replacement Caps

So the 45watt de-soldering red bulb iron is safe; as in not too hot??
Also thanks for the link at digikey.

Re: Original Xbox Replacement Caps

well, it's not temperature controlled so it's a bit risky.
use it fast - dont use the bulb, it wont work anyway.
just melt the solder and rock the cap out - clean the hole(s) out later

Re: Original Xbox Replacement Caps

Well I received the Caps from digikey from the link jayjr1105 posted.
When looking at the picture from NeMesiS34 xbox 1.1 board, the numbers are a little different on the cpu caps then the one's I have.

Example:

His: K759 -- mine: K750 1st line
his: 6.3T44 -- mine: 6.3V18 2nd line
his: 1500 -- mine: 1500 3rd line

Does it matter; just to be sure ?

Thank-you,

Re: Original Xbox Replacement Caps

See page 12 of the datasheet, first line is series, second is voltage withstand rating and production date.
Third is capacitance.

Re: Original Xbox Replacement Caps

Hello,
I'm still trying to get my 1.0 xbox working, but it's not there yet.
Things I've changed so far:
I've removed the clock cap and cleaned around it.
Replaced the 5 1500uf CPU caps that were leaking on their tops.
Tried a different power supply; no change.

The next thing I'd like to replace are the 2 power supply caps near the power connector.
The thing is they are 3300uf 10v caps (C1G1, C2F3) on my board.
NeMesiS34's reference guide lists them as 2200uf- 10v, and in his pictures only used 2200uf- 6.3v.
Shouldn't I at least use 2200uf 10v polymers or try to find 3300uf?

Sorry I'm not that familiar with capacitor ratings.

Re: Original Xbox Replacement Caps

what exactly is happening?
and why does the picture look like you bent the legs outward on those polymer caps?
did you order the wrong diameter ones? xbox needs 10mm caps

Re: Original Xbox Replacement Caps

I ordered these that jayjr1105 suggested in a previous post:
https://www.digikey.com/en/products/...AAE014/6196333

Yes the leads didn't match up the holes, that's why their hovering over the MB

The xbox still has the original problem of FRAG, but sometimes will boot-up and work for a few minutes before freezing up.

The 2 3300uf capacitors don't look bad, no leaks/Bulge. Can they be bad without any visual signs?

Thank-you,
Mike

Re: Original Xbox Replacement Caps

what caps are on the psu?
is it delta or foxlink?

[Mike.F]

Re: Original Xbox Replacement Caps

I have 2 power supplies.
My original is an NMB Technology.
I also bought a replacement, it's a Foxlink.
The guy that sold me the foxlink claims it's working fine and was tested.

My Xbox behaves the same way using either supply, so I guessing it's still the system board.

Is changing the 2 3300uf's a logical step forward?

Thank-you,
Mike

Re: Original Xbox Replacement Caps

probably not the 3300uf caps,
this is where test gear is usefull - it may be a smaller cap or one related to the ram or nvidia chip.
if the fox psu has any 1200uf caps on it - they may be suspect.
that said, i'v not seen a u.s. one so it may be different from the 230v ones
