almost all narrow band oxygen sensors have exactly the same output, or very nearly to. they all have 0-1V output.
the O2 sensor measures the oxygen content by way of a nernst cell, and the response of this is such that the output switches very quickly at stoich mixtures... this is 'cos either side if the stoich mixture, there either IS or ISN'T oxygen.
a sample graph is 
or
the only operational differences between sensors is that you either do or don't have a grounding wire for the sensor (so that you can ground it near the ECU and eliminat problems from poor grounding from sensor to exhaust to manifold to head to block to chassis to ECU)
also sensors with a heater will stay at a more constant temperature and heat up in maybe 30 seconds, and won't cool down during cruise or idle conditions.
non-heater can take a few minutes to heat up and can cool down too much during idle/cruise, IF too far from the head (mayybe 1-1.5ft)
so basically yes, almost any narrow band sensor is compatible with anything that uses a narrow band sensor.. it's only wideband sensors you need to be careful of.
all narrow band sensors have a 0V to 1V output that switches at stoich...
if you have seen one of those LED AFR meters on a stock car that has closed loop, and seen it flickign back and forth, you'll see what i mean about switching (which is what the ECU uses to tell it to adjust mixtures)
hope this helps
