660 Mbits per second photo-diode amplifier on 3.3V rail
I think you will be able to find a close replacement for your original Hamamatsu part, if your requirements aren't too strict. 

A google search for "InGaAs TO-46" will turn up as many parts with integrated TIAs as without. 

A couple examples I found with a quick search are at OSI Optoelectronics and Kyosemi.

If you do want to use a separate amplifier, there are chips designed strictly as photodiode TIAs for optical communications applications. For example, Maxim has a couple of options.
