    Need replacements for Samxon HP

    I've been looking through all the best brands (rubycon, nichicon, UCC) with little success (edit, I mean I find them out of stock, or only stocked in other countries). Is there a mid-range brand for these

    Must be:
    315v-400v
    470uf (560 maybe)
    1.7ARMS
    30mm diameter max
    40mm height max

    Mid-range caps are fine and you guys are up to date on other brands

    for: Plasma TV main power board

    I know some are bloated and I plan to replace as many as I can

    Middle mains are Samwa

    There are a couple on Mouser after clicking through their filter system.

      One of the first places I looked. I used their filter system. The only one within a good price is 85c. I'm not sure I'm comfortable with that

        Is Hitachi available? Panasonic?

          Already searched through through panasonics series

          I'd be just fine with a medium-grade brand right now. Might just bump up V/uf for life purposes

            Come on guys I gave you the caps database, which is surprisingly like the #1 link on a few searches I came across. I should of put ads in there I knew it!

            Suggestions please

              You're not going to find a cheap capacitor with the ratings you specify unless you look on the used market.
              The ones I linked are all fine, the 85°C version would be no problem unless the designer of that TV was really stupid.
              Here is a list from Digikey, very similar: https://www.digikey.com/en/products/...ACeLCpq1JKCdQA

              EDIT: Well, after looking at the Samxon datasheet it looks like they should be 35mm wide, unless this was a custom order.
              If so there are allot more choices.
              That said bulk filtering caps rarely fail, so if you want to cheap out you could just leave them alone.
              I would check in-circuit ESR and capacitance though to make sure it is in the ballpark.

              EDIT2: And if the caps are the same as in this users post this all feels a bit meh:

                No, the HP 315/470 has two, one 35 and one 30x40

                I'm not looking for cheap, just decent mid-range.

                also that is the same board on the same plasma TV with the same problem

                  Took the whole VRM FETS off. Huge pain in the ass. Some traces unglued a bit but they're still on

                    Well if you change the DC rating to be from 315v in the search you find this one for example:

                        This one does turn on, you can hear the audio, it just takes about an hour for the screen to get brighten up. I already found several more bloated caps under one of the VRM heatsinks

                            Oddly enough the GK does not have a 35v version on the datasheet, but this board does. Must be custom order

                              This is about as close as I can find:
                              https://www.digikey.com/en/products/...71MELB/2540761
                              https://www.digikey.com/en/products/...MELB40/2540156

                              ^ Both are 470 uF caps in 30 mm dia., but one is rated for 315V and the other for 400V. Height for both is 42 mm... which is the smallest you can get. Do you really absolutely must keep the height below 40 mm? With the case close on the plasma, is there really no more space / height inside? Otherwise, if you can go up to 47 or even 52 mm, that opens up even more choices, like these:
                              https://www.digikey.com/en/products/...MELB45/2540435
                              https://www.digikey.com/en/products/...MELB45/3929841

                              And yeah... I know you said mid-grade, since you probably want to keep the costs lower... but that's the unfortunate part about plasma TVs - they really do need quality caps if you don't want to do this repair again. And also, mid-grade caps aren't much cheaper - at least not on Digikey. I'll try to check eBay for you tomorrow. I know I have bookmarked a few sellers that actually had good quality caps for relatively cheap. Just don't remember if they had HV units.

                              BTW, maybe another (possibly cheaper) option would be to look for used Panasonic Viera / plasma TV boards online and just take the caps from that?

                              Either way, I too also always cringe when I see a PSU with big caps that need replacement. This is why I hate APFC on cheap ATX PSUs - never ends up being a cost-worthwhile repair if it needs new primary cap(s). For this reason, I always pick up broken Sony and Panasonic TVs on the side of the road - at least LCDs. If I had a truck, I'd pickup the rear projection units too. Those probably have decent caps too (again, at least Sony does, for sure.)

                                Height isn't a restriction here. But only the LGU and LGX have the equivalent ripple (1.7)

                                I did search 400v, not sure why those didn't come up on dgk

                                    Well, one of them is rated for 1.68A... I doubt that will break the bank here.
                                    Also, these are the 120 Hz low frequency ratings. I'd say look at the higher frequency - if it matches to within 0.3 Amps, it's probably good enough.

                                    I only get hits back from this thread and your database (for a different cap manufacturer.) :\

                                    I checked the list of caps I jotted down from an old Samsung plasma I found recently, and it also has Samwha PL caps here and there (4x 315V 440 uF). Also some PT series.

                                    I wouldn't look for datasheets for these - just go with whatever brand/series has the highest ripple current and with longest endurance/life. The PL on my Sammy are on two very hot boards at the end. Not sure what these are called (any plasma TV folks want to fill me up on this? ) In any case, since it's hot there, just go for the best specs possible.

                                      Seems like a series used specifically for certain manufacturers.

                                      I just matched UF/V (sometimes slightly higher V) with a slight/middle up ripple and down ESR. Just matched the datasheet if it was 120hz or 100Khz. The TV still technically worked, hadn't blown. I figure with all caps panny/ruby/ucc/nichicon and 105c 2000+ hrs it should be fine for a few more years

                                      hardest thing was taking the series of fets off to get under one of the heatsinks

                                        These caps will very likely outlast the screen.
                                        I find that even Japanese GP caps used in applications calling for mild-to-medium low ESR tend to last longer than "LOWESR" garbage from China/Taiwan/Korea.
                                        Only exception is APFC circuits in PSUs - those seem to kill just about everything... unless caps are grossly oversized.

                                        Oh BTW, when I found that Sammy plasma, I found something interesting on it that you might like. Just gotta see if I've pulled the pictures from that.
