HDMI is digital and component (with "RCA" connectors) is analog. Why do you prefer analog to digital for video transmission? Unfortunately, yes, HDMI has HDCP. I try to use DVI or mini-DVI where possible.
DVI can carry HDCP just fine. In fact, if you have a recent desktop display with a DVI port, there's a good chance it has HDCP. And if you're running a recent version of Windows with a recent graphics card, there's a good chance you're actually using it without realizing it.
