Not quite, the term IC also comes with connotation you don’t want to be a manager track.
Many software engineers (including myself) much prefer the IC route.

Ok I probably mangled this but IC just paid for itself in my mind via increased understanding, nuance and useful brevity.
There's also the verisimilitude that it can also mean an inferred ceiling. For example, Principal <whatever area> Engineer role[s] at Microsoft is [are] typically the highest that you can go - if you stick to the IC (read: non-managerial) track[s].
