Names vary depending on the manufacturer.  For example Texas instruments might make a LM380 while the NTE replacement part is 740A.

But for the most part, ICs are named similarly to the first one of that type.  The "741" single op-amp was very popular, and is made by many companies.  Most of them use 741 in the name even though they're not the original manufacturer.

Same for the 4558 dual op-amp.


But in general the name of the IC doesn't tell you anything about what's going on inside.  Not like tubes where the numbers actually describe the number of pins or something.  If you want to know what the names/numbers mean, you have to look it up.

OF COURSE there's a tonal difference from different op-amps, but that's not noted in their codes.

but if you check their datasheets you'll see they have different frequencies range. some work from AF to RF.
this frequency range is, IMO, what defines their tonal characteristics.

As a rule of thumb, always refer to the manufacture(s) data sheet(s) and compare specifications between multiple manufactures.

Hi...i am a new user here. As per my knowledge Cs are named similarly to the first one of that type.  The "741" single op-amp was very popular, and is made by many companies.  Most of them use 741 in the name even though they're not the original manufacturer.Same for the 4558 dual op-amp.
