Definitely NO for HDTV Directv uses a SAT C LNB for 110 that downconverts the satellite to appear on unused 119 channels and no DISH LNB is capable of replacing this.
Dish Legacy LNBs for 61.5/110/119/148 and DirecTV 101/119 LNBs are compatible. A Dish is a dish so they are compatible though the mounting brackets for the LNB may require some modification.
But if you let us know exactly what you are trying to do it would help us help you.
