Almost ALL single opamps have the same pinout. Duals and quads also have the same pinout as each other.

The 741 opamp is 45 years old and does not go above 9kHz. Most modern opamps go up to 100kHz perfectly like the MC3407x, TL07x and TL08x.

An OPAx134 audio opamp goes up to 250kHz perfectly and a TLE214x goes up to 400kHz perfectly.

I would avoid using an op-amp that has a much wider bandwidth than needed.
You are likely to run into problems with oscillations and instability.

i have a doubt.whether there will be any change in design of the circuit if i changes the op amp with the same pin out as that of the previous used one

When posting a request in a forum try to post a title that gives a clearer idea of the topic.
A title such as "help" or "pulse" is totally useless.
Also do not post multiple threads on topics that may be the same or related.
