It's not corrupt. Use OpenOffice or LibreOffice Calc to open it.
If you have an old Excel, then it may not understand the xlsx format. Or maybe your download was just bad, get it again. |
Anyone has a similar list of Panasonic DS-850? Is there a one-size fits all capacitors?

A question about the file listed above- There are about 32 part numbers that don't match anything on Mouser or Digi-key- I'm guessing they are obsolete. I'm also hoping that someone who has done the cap replacement for the 1980 has a list of replacements for these obsolete part numbers. Or direct me to where I can check them myself- I've looked all over and can't find a list of replacement panasonic capacitors.

Did you check Panasonic for a cross reference?

What I am doing now is looking through the parts list in the manual to find out the volts and farads of the unknowns, so at least I can match that. I'll post the file once I'm done, for future reference. |
One thing I found that may be useful is that you can tell the voltage and uF from the part number. The voltage is determined by the first letter after the "A0" or "A1". A=10v, C=16v, E=25v, H=50v, J=6.3v. The uF are determined by the last 2-3 numbers. Decimals are designated with "R". A "0" on the end means the number is multipled by 1, a "1" on the end means the preceding number is multiplied by 10. So, 0.47uF="R47", 4.7uF= "4R7", 47uF="470", 470uF="471". So an example- "ECEA1CU471" is 16v 470uF.
I have no idea what all the other characters mean, but this helped me figure out the parts with no cross-reference to current ones. |
The other letters will refer to other parameters such as type (construction, chemistry, tolerance, temperature rating, etc.).
Many of the numbers you cannot match may correspond to the bad SMD devices (I don't recall, it was nearly 5 years ago when I went through the drill) and that have been discontinued. |
It appears the 4th letter is the one that denotes the package- all the through hole caps have an "A" in that position, all the SMDs have a "V". there are also "C", "1", "0", "U", "F", "X" but not sure what they mean yet.
Another addition is if the last number is "2" then it means multiply the preceding number by 100 for uF. So "ECEA0JU102" is 6.3v 1000uF |
