CA3046 vs CA3086?

[jorgen.bergfors at idg.se]

I have a couple of schematics that use the CA3046 and the CA3086. For practical 
reasons I would like to standardize on one of them. Both are NPN transistor 
arrays with the same pinout. Farnell stock both and the CA3086 is slightly more 
expensive. Is it better? The higher number suggests that it is newer and 
therefore might be an improved version. Is this true? Or are they actually 
incompatible?
