First you must determine the minimum requirements for an op amp in your circuit, and then screen
the op amp parameters for candidate parts. The OPA627 and the OPA637 are not interchangeable
with one another in many circuits, for example.

Rayma, thank you, so I can just take OPA2134PA and replace by OPA1654, also as dual OPA627 because they have same circuits, but ofc I cant use OPA637 because it's require Gain >= 5, and there is maximum G=3 in those circuits
