Component video requires a 75 ohm cable for each of the 3 colors (red, green, blue) to pass the bandwidth. Stereo A/V cables (even the short ones) have 1 video cable that is 75 ohm and 2 stereo cables that are significantly less than 75 ohm. It may work on a 3 foot run, but you'd be a LOT better off with a true component cable.
FWIW, any shielded cable for audio or video should be 75ohm. But there is no such thing as a 75 ohm RCA ("phono") plug or jack. The plugs and jacks are 50ohm. So there is always an impedence mismatch.
Years ago McCormick developed a connector for digital coax cables that "funneled" the impedence down from the cable to the RCA jack to prevent reflections. It would work great for analog audio & video, too, but at $200-300 per cable wouldn't be economically practical.

Easy And Cheap and it has better picture than most of the expensive cables if you assemble them correctly with no stray braids touching center conductor.
