    Asrock 939Dual-SATA2 - MCZ or HZ ?

    I need to do some replacements on this mobotherboard. CE23, 3300uF, 6.3v UCC KZG is bulging on mine. I see re-capping for this mobo discussed elsewhere; https://www.badcaps.net/forum/showpo...20&postcount=3

    amartools replaced his KZGs with Rubycon MBZ.

    I was able to locate 10x25mm (discontinued) Rubycon MCZ (633300MCZ) on CapKing, it is spec'd at .009 ohm, 3230 mA (a bit better than MBZ). 10x25 Nichicon HZ (UHZ0J332MPM) is available from Mouser and is spec'd at .0065, 4690. Both beat KZG (.012, 2800)

    Any reason not to go with HZ here ?

    Possibly. See PCBONEZ talk about caps

      Thanks rcaps, I did view that post. I need 10mm diameter here, wider footprint won't fit (see pic). The HZ cap was the best spec I could find for a 3300uF 6.3v 10x25mm. MBZ, MCZ,and HZ in this size are all rated at 2000 hrs (so is KZG); I could not find anything with better specs in a 10 mm can. Based on specs alone, it seems I should go with Nichicon HZ. Feedback on comparative reliability is what I am searching for here; many on this site seem to prefer Rubycon.
