Without checked bags it typically takes ~60 minutes, but even 2 hours can be tight if things go against you.
IMO, a tight connection is worth the risk so long as there is another onward flight the same day. IOW - if you have a choice between tight and long, take the tight one, as you should be reaccomodated on the later flight if you misconnect.
Might be more complex if you check bags; I never do.
