Hello Harry!
I selected OP4177 as a replacement for LM148 in my design based on the specs given in datasheet. I found it better in every aspect e.g. offset, bias current, supply current. Slew rate , gain BW were comparable too.
Now when it is not working in my final board, I am in a fix. Even if I try to choose another opamp now, I really do not know which parameter to look for in the datasheet to ensure that the problem does not repeat.
reason for changing LM148 was its non-availability in SOIC package with +125degC operating temp range which is required in my application.
