RCA Cables to be used for Component Video Cables

by kbankes / February 27, 2006 2:39 AM PST

Is it possible to use 3 standard RCA cables as component video cables? If so, is there any real compromise in using them?
I guess my real question is, what is the difference between 3 RCA cables and the 3 cables used in a component video setup?

Yes there is a difference!!!!!

RCA A/V cables have one video cable ( 75ohm coax) and two audio cabels.
Component cables have 3 video cables (75ohm coax) since all 3 have video informatin you should use compnent cables.
Radio Shack house brand will do the job very well. $390~49
Home Depot has some RCA brand cables that are also good $35.
$50 is the most you sould have to spend.
Any place that carries Mon$ter Cables will try to talk you into buying them, shame and guilt you they will.
But it's your money. John

I agree... but...

If i were to use 3 standard RCA cables (all 3 dedicated to component video output) instead of 1 component cable (consisting of 3 cables), is there a difference? Please keep in mind, I already have other RCA cables hooked up to the audio output.

great question

when our installers make cables for customers, all they do is take a 75ohm coax, strip it, and put a rca head onto it. he uses that for subwoofer, rca, digital coax, AND component cables and they all work great.

but i try this in stores and its only worked with a handfull of tv's. so i am unable to give you an answer.

have you actually tried it on YOUR equipment?

If your handy with tools and a soldering iron. 3 seprate 75ohm coax cables will work fine for component. You can use 75ohn coax for audio, won't make it sound any better, won't hurt.
I am handy tools, part of my job. But I still buy pre made ones molded into one cabel so much easer to handle, hook up and looks better. John

Minor difference, but how much can you really tell...

I received a gift of Phillips cables for my new Panasonic (42PD...), upon inspection, we discovered they were a set of composite cables (Yellow video, Red and White audio). The were all I had at the time, so I tried them out in the Component inputs. No problem, picture is great. I went out and bought the set of Phillips Component cables later (Red, Green, Blue). After thoroughly inspecting the packaging, the only difference was that the Component set called out a different sheilding within the cable insulation. Both sets are, of course, RCA-type cables so connections were no problem and I cannot tell a difference in the picture.

Does anyone know, from a technical perspective, if there is a difference in signal carrying capacity of each of these RCA-type cable sets or if the sheilding has any effect.

The math will boggle your mind!!!!

Has to with the diamiter of the center conductor and the distance the outer shield is from the center conduter. Lots of fun equations, I leave them up to the cable designers.
Some cables will use 75ohm coax for all 3 cables on a AV cable, some only use the 75ohm for the video. To be sure you get the correct cable for composit, buy composit cables.
If you realy want to get into the therory more check out this link. John
