[Heath] Zener replacement

[Robert Groh]

The answer is 'Yes'. Nothing magic about the Heathkit parts (with a very few 
exceptions).  Just match the electrical characteristics (voltage and power 
rating being the two most important for a zener) and accommodate any physical 
differences as required and you should be fine.

Subject: [Heath] Zener replacement

  I'm asking the group if anyone can tell me if it's OK to replace a Zener 
listed as a 1n4166a [52-25]
with a standard zener rated the same. The 1n4166A is no longer made - it was 
used in a heath
power supply in a positive and negative 15 volt 1 watt application. There are 
many newer ones that
control 15 volts with 1watt. Can one of these be used as a direct replacement?
Thanks for any help.
Brian
