Hello Venky,

Here are some parts you may consider. They have similar or better bandwidth, maximum voltage offset, slew rate, supply current, and voltage noise specifications as the LF442CN. They are also +/-18V supply capable, like the LF442CN, and come in the PDIP package with the same pinout.

OPA2137
TL032
TL062
TLE2062

Please make sure to double-check specifications, pinout, and package dimensions with your original design to be sure. Let me know if you need anything else.

Regards,

Daniel

Hi Venkatesh,

is a low supply current of OPAmp essential in your application?
