Obsolete parts source?

[Nico Coesel]

I'm in need of a Harris/Intersil HFA5253 chip to fix a frequency
generator. The problem is: it got obsoleted in 1998. I tried to google
but the problem is that there are too many links that provide no
answer. Does anyone know a reputable parts broker who could supply
something like this?

Partminer comes to mind. They all charge a premium for hard to get
stuff.
Call the manufacturer. I had gotten some obsolete CD series cmos from
leader electronics years ago to fix a freq counter that died.
