While scraping together enough parts to satisfy the DigiKey $25 order threshold (sans $5 service charge), I decided to open up my 2465B and see which electrolytic caps were in the PS section (which appears to be soft, as I previously posted). I was able to track down replacements for most of them, but I'm stumped on three other types. Two of them are 672D series, the other 39D. All three appear to have United Chemi-Con logos. More specifically:
- 672D150 - 250uF, 20V, 105C
- 672D? - 180uF, 40V, 105C
- 39DX1314 - 290uF, 200V
Both the 672D and 39D were Sprague series, but I'm not sure if they were the same as these UCC caps. Neither Vishay/Sprague nor UCC have any information about either series on their websites (Vishay has a U673D series, presumably a lead-free version of the 672D, except that they are all radials, whereas at least one of the 672Ds in the scope is an axial). I googled six ways from Sunday and came up empty, though I found a cross-reference on the Illinois Capacitor site (672D -
(radial) or KME-T (axial), Nichicon PZ (radial), and Panasonic NME (axial). Of course these last four may have worse specs than the Illinois caps and perhaps the 672D as well. An actual spec for the original caps would settle the matter, but I can't locate that either. Any other suggestions for determining what cap(s) would be suitable replacements? Just get the lowest-ESR, highest ripple 105C axial that will fit? One more thing - none of those three capacitance values are available in the axials I found; closest are 330uF and
220uF. How critical are the values in the 2465s supplies?Thanks, TM
