will this replace the Mod# ND3933 Thermocouple?

i can't say for sure, but i took my old part out of the fireplace and compared it to the image online- they matched up perfectly- not hi-tech, but it worked for me

Will this replace dt-500cmn

Maybe. If your pilot flame spreader looks like a three way water slide (made by PSE for Honeywell) then yes. If you flame spreader looks like a round space ship, no.

Will this work for a Regency P36D?

I dont know! I used it for my Dovre 400 stove and it was a perfect fit!

How long is the probe - not the entire thermocoupler.

Probe is approximately 3" long.
