What charts do I need flying VFR between KPRC and KLAS?
If I understand correctly, your question is "can I substitute a TAC for a sectional on a cross-country flight?" However, assuming that you're flying under part 91, there is no legal requirement to have any charts on board at all. 91.503 does require them, but only for large and turbine aircraft, and the FAA has stated that electronic charts are allowed instead of paper.

There are a few places where it is required to carry a chart in the aircraft, per the Special Flight Rules Area regulations in 14 CFR 93. Some examples are:


Near Los Angeles International Airport (93.95(c))
The Hudson and East River Exclusions in New York City (93.351(d))


So unless 91.503 or one of the part 93 rules applies to your flight, legally you can carry whatever paper, electronic or hand-drawn charts you like - or none at all - although if you bust restricted airspace and the FAA come after you, not having charts on board may not look good. (Of course, if you do have them then the implication would be that you didn't use them or don't know how to read them, which isn't good either.)
