    Suggestion for Panasonic Replacement Cap

    Hello everyone - 1st post - I was hoping someone can help me with the closest spec of a Panasonic cap for the Samwah WB series on my board

    The TV model is LN52A650A1FXZA
    The power board with 2 bulging caps - BN44-00201A
    The 2 cap locations are CM851 and CM852 - both caps are identical
    The 2 caps are Samwah WB 1000uF 25V 105C Size 12.5x20 MM
    Pics are attached along with the WB series data sheet in PDF -
    I can use Digikey or Mouser

    Based on the reading I've done here I would like to go with Panasonic replacements I am not sure how to pick the closest specs in Panasonic (other than the obvious 1000uF and 25V) . If someone could assist me with that it would be greatly appreciated.

    Thanks

    Really any good brand low esr capacitor will do.

    Panasonic FR series are my usual replacement.
    I buy them form HM Comp on eBay, but don't know if they deliver in the U.S.

    Also I'd replace the caps next to the ones that have failed just for good measure.

      You can get Panasonic caps from Digikey in the US.
      Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
      For service manual, schematic, boardview (board view), datasheet, cad - use our search.

        Just find the right values and dimension in the spec sheet, then type in PANASONIC P/N into the DIGIKEY/MOUSER search box.

          I wouldn't be too fussy--The set is a fair age (7 years!)--even a cheapo crappy 105 deg C cap of the right value will outlast the rest of the set!

            OK thanks - Ive narrowed it down on Digikey - I can kick myself - had a great desoldering gun with a vacuum on it - gave it away a few years ago - anyway - the set was purchased in 08 by a friend and in 2013 Samsung replaced some caps in August of 2013 - so 1 1/2 years later - these 2 caps are bad - I am guessing they didn't want to go the extra 1.50 to finish the job - go figure - Thanks again for the responses and if I may ask - on the Digikey table - the column for ESR is blank - just has a dash in it - I've filtered to FM and FR - they do not list an ESR - or can I just assume these will be a low ESR

                Thanks
                UCC KZE is an almost exact match. Same size, same ripple, slghtly lower ESR, and same 5000 hour endurance.

                  ESR on FM and FR are lower than WB, but ripple is also lower. if you have room for 22mm height, 35v FR will work.

                  For some reason Digikey doesn't show ESR, just impedance, which is essentially the same.
