The two examples are seen quite often in literature (especially in technical/medical texts), with the former being more common. Are they strictly equivalent? What subtle nuances distinguish the two? Thanks for your comments.

I am a native English speaker and writer. In the field of Psychology, when we speak of word associations, this is where "associated to" sounds more correct than "associated with". For example, "I associate the smell of freshly baked bread to my grandmother when I stayed in her country home." What do you associate the ocean to? I associate it to long, hot summers spent snorkelling and and sailing with my father."
