I have an old SunPak AF4000,still works fine with Nikon film SLR. Is it compatible with my Nikon Dslr D50?

As long as it has a trigger voltage of less than 12v

You can use older flash units on your camera. Your camera won’t be able to take advantage of the TTL metering function which works like magic with the SB-400 and SB-600 Nikon flash units.
WARNING!!!!
Be careful using old flashes on newer cameras. The hot shoe voltage handling capability is limited on the camera. It is really hard to find this information in a Nikon manual since they don’t put it in the specifications area! The D200 and D40 can only handle a maximum of +250 volts on the hot shoe. I assume that the D50 has a similar limitation. Negative voltages and anything over 250 volts could damage the flash sync circuitry in the camera.
My old Sunpak 411 flash (cira mid 1970s) uses a trigger voltage of +300V at the hot shoe as verified by the schematic. Too bad since it really packs a punch. You can measure your hot shoe voltage if you have a high-impedance (100 megohm or better) voltmeter available. That sort of voltmeter is uncommon unless you have access to an electronics lab with fancy equipment.
Considering the age of your flash, I would NOT use it on your D50 unless you can absolutely verify the trigger voltage. See if you can dig up a manual or a schematic for the flash.
If you’re hell bent on using this flash, there are adapter units out there which will provide a safe interface between a high voltage trigger and your camera.

The price difference between this adapter and a new flash which supports TTL metering isn’t much.
