Need help: Diode replacement HZ12-A2, GP10D

[Kecap Manis]

Hi All,

I need help with replacement for older diode in a circa 1980s amplifier. A few of the diodes leg was badly corroded (one is broken upon cleaning) by glue from nearby elco. I'm hoping to find a similar spec new replacement.

Hitachi/Renesas HZ12-A2 -AX in regulator section
Possible replacement:
a) Vishay TZX12C, this is available at Mouser,

b) NTE5021T1, this looks to be EOL

GP10D -AX Unknown make possibly Hitachi or Toshiba
Possible replacement: Vishay GP10D or RGP10D

Much appreciate if somebody could have a look to see if the possible replacement is a good substitute. Thanks.

Cheers,
Heru

its a 12v half watt zener, unremarkable, ands its 'error code' from the hitachi datasheet says it errs on the high side of 12 i.e. 11.9-12.4 possible range.

If this is for the regulated supply its likely 12v is needed here, so this being the future, any fine 12v half watt zener (or even a full watt) should do from mouser
