My film SLR is Canon EOS A2 and flash Sunpak 433. Just wondering if that flash unit can be used on the digital SLR from the same Company - Canon Rebel XTi. Please advise, Thanks.

Trigger voltages can be a problem for digital cameras with sensitive electronics on board. The "upscale" Canon cameras can take quite a bit of voltage from the stobe, but the Rebel line is supposed to be limited to 6 volts.
The list at http://www.botzilla.com/photo/strobeVolts.html says, "It's your call," because the Sunpak 433 has been measured at "less than 8 volts" when the XTi is supposed to be limited to 6 volts. At least it's not 200-250 volts like some strobes, so maybe there's not that much risk.
I looked for a definitive source for the trigger voltage for your flash and didn't come up with anything. I'd imagine that Canon might be willing to help you with this decision.
I read something along the lines of OMG's thoughts and it seems like the TTL will not work, but I don't think he was thinking about damage to the camera. At least we didn't just say, "Sure, why not?" and let you plunge blindly forward and trash your camera.

The old FD lenses (for the A-1) will NOT work on a digital SLR because they use levers between the camera and lens for aperture movement. The Canon digital SLR are EOS mount which use electronic connectors between the camera and lens. The old EOS lenses WILL mount on the DSLR. The Rebel and 20D use smaller sensors with the 1.6x crop factor, so wide angel lenses will no be so wide angel. Canon lenses work ONLY on Canon cameras.

Most likley the electronics are different in how the body communicates data to the flash unit. Check with Canon's website and see what flash units are compatible with the body you'd be using.

"check its specifications to see if it supports “E-TTL flash metering.” If it does not, or only lists “Canon TTL flash metering” then it most likely will not work. For details see the section on flash metering with digital cameras."

any of the old camera flashes, lenes, and etc can be used on the digital SLR

If the hot shoe on both cameras are the same, then it might work. You can check your owners manual, too.

I can't see why not. Give it a try. It can't hurt your digital SLR.
