    Replacements for old Cap series?

    I am fixing my brother's mobo, and pulled out some blown electrolytic Al caps, but the series that they're from is discontinued. Can anyone recommend some similar replacement caps? Thanks for looking.

    -Rubycon 6.3V 2700 uF, MFZ series (model T0528)
    -Rubycon 6.3V 220uF, ZA series (model A0532)
    -Rubycon 6.3V 470uF, ZA series (model A0537)
    -Rubycon 6.3V 220uF, ZA series (model A0538)
    -Rubycon 25V 47uF, YXG series (model A0534)
    -Elna 16V 100uF, M tolerance

    Not without diameters.
    .
    MFZ and ZA are the 'models' aka 'series.
    The other numbers are just the factory and date code.
    T0528 means 28th week of 2005 [05].
    .
    Blown Rubycons suggests a PSU problem or really bad cooling.

      It came out of a Dell XPS with liquid cooling, so I don't think it's that. It looks like (and I may be off on the proper name for the component, it's been awhile) a small step down transformer went ka-boom, and the caps in line suffered. The PCB looks a little burned, but the paths are all just fine, and overall, it looks alright. My brother already tried replacing the PSU, just in case, so, when this gets fixed, that should also fix that issue if it was the cause.

      I'll see if I can find diameters, but I don't think dell was in the habit of posting their OEM mobo schematics...

        ZA = > YXJ, YXG, ZL , ZLJ (from: http://www.rubycon.co.jp/en/products...ace/index.html )

        YXG is not discontinued.

        MFZ is probably a custom series... can't help you there. Doesn't show in the discontinued list or I'm blind.

          Here is what Rubycon said.


          The MFZ series was designed for a specific OEM because of this I have no
          data to cross.

          The ZA series was replaced with the ZLJ series and the YXG series is
          currently available.

          MFZ - No replacment

          Rubycon 6.3V 220uF, ZA series (model A0532) - 6.3ZLJ220M5x11
          Rubycon 6.3V 470uF, ZA series (model A0537) - 6.3ZLJ470M6.3x11
          Rubycon 6.3V 220uF, ZA series (model A0538) - Duplicate 6.3ZLJ220M5x11
          Rubycon 25V 47uF, YXG series (model A0534) - 25YXG47MEFC5x11

          Can't find the 470 uF ZA cap replacement anywhere. Recommendations for a replacement for that one?

          Thanks for all the help so far guys.

            No one publishes motherboard schematics.
            Don't want their competitors to get their hands on them.
            .
            Most XPS aren't known for exceptional cooling.
            .
            Water cooling makes CPUs happy, not caps.
            In fact it probably reduces air flow to the caps more often than not.
            Granted it depends on the setup.
            .
            Check the MOSFETs closely and make sure none look pitted, cracked or melted.
            .
            Intel designs most Dell boards and then they are manufactured by Intel or Foxconn.
            [Obviously Intel doesn't do their AMD boards....LOL..]
            .
            MFZ is a custom ordered cap so there won't be a data sheet.
            By where they are found they are a good grade so:
            I would use Nichicon HN for those unless there are none that will fit.
            .
            ZA [data sheet attached] is best replaced by HM, WG or similar although in some sizes FR or FM might be good enough.
            .
            YXG are close/equivalent to HE and KY.
            [Depends on can size.]
            .
            Can't say for sure on the Elna without a series name.
            But: a 100uF 16v usually only needs to be like an FC or PW.

              Yeah, Rubycon says you can replace MCZ with ZLJ ro ZLH [or something] too and that's a load of crap.
              They aren't even close..........
              .
              Is ~always~ better to check specs yourself.
              .
              And there is this:
              Rubycon from reputable dealers - hard to find.
              Nichicon, Chemicon & Panasonic from reputable dealers - easy to find.
              .
              ebay is literally flooded with counterfeits.

                  As for the Rubycon MFZ ... if someone wants to actually check their ESR (for future reference what to replace them with or something), you can grab them from the PCMC Store. From what I know, they were mainly found in early XBOX360's..
                  (so OEM only .. no Idea how that guy got hold of them..)

                    Rubycon MFZ should be equivalent to Nichicon HZ or Samxon GA.

                    The datasheet exists, probably typed out roughly, as are many datasheets for experimental series.
                    "We have offered them (the Arabs) a sensible way for so many years. But no, they wanted to fight. Fine! We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

                        FYI: 2700uF 6.3v MFZ has ESR of at most 7mOhm. That's better than MCZ and the same as Nichicon HZ.

                            Nope...
                            You want the same or more Ripple and the same or less ESR.

                              It would be good to learn the relative characteristics of the parts you're dealing with. Nichicon series like PS (PR), PM (PL) and PJ (= UCC LXV series) were low Z when they were new, but for the PM (PL) series, that was some 25 years ago. I don't think you should go any worse than the Nichicon PW series (= UCC LXZ series), and maybe not even worse than Nichicon's PA or HE series (~ UCC KZE or Rubycon ZL).

                                It would be good to learn the relative characteristics of the parts you're dealing with. Nichicon series like PS (PR), PM (PL) and PJ (= UCC LXV series) were low Z when they were new, but for the PM (PL) series, that was some 25 years ago. I don't think you should go any worse than the Nichicon PW series (= UCC LXZ series), and maybe not even worse than Nichicon's PA or HE series (~ UCC KZE or Rubycon ZL).
                                FYI:
                                The ZA series has much much lower ESR than all of the above.
                                ZA is even lower than Panny FM.
                                See data sheet posted earlier.

                                You can see how the more common 'good caps' relative characteristics match up here.

                                  Thanks PCB, I really appreciate your help. I ordered the ones you recommended.
