    I am familiar with using solid state relays to switch 110VAC using a low
    DC voltage to activate. Can these also be used to switch 12VDC (to pick
    a 12 volt mechanical relay)?

    Assuming you mean **to replace**, sure.
    Select such that the on state resistance won't affect the results.

    On the 2nd page under "Relays"
    "Solid State(3854 items)",
    enter some parameters and see what's available.

    A solid state relay that is designed for AC won't work to switch DC
    and Vice Versa
