2147D OpAmp Substitute

[opacheco]

Hi to everyone again!

Does anyone knows what will be a very good substitute for an 2147D OpAmp?? I found any original part in my country at all.

Any comment or advice will be appreciate a lot!

Thanks anticipated

It is not easy to find a replacement for that opamp because it works at very high voltages (+/- 28V) and has a very low quiescent current (175uA), what's your application? can you measure the voltage rails?

Maybe try this: https://www.retroamplis.com/epages/62070367.sf/en_GB/?ViewObjectPath=%2FShops%2F62070367%2FProducts%2FIC-NJM2147D

user 37518 let me to measure the voltage between 8 and 4 pins of the original OpAmp and let you know. The NJM2147D / JRC2147D look like the same OpAmp I think but different manufacturing company!

Thanks for your help
