App note from KEMET about the replaceability between ceramic and tantalum capacitors to each other. Link here (PDF)

Ceramic capacitors have a multitude of dielectric types available and each of these types is characterized by their sensitivities to temparature, but not to voltage or time. This paper compares the X7R, X6S, or X5R dielectric types of ceramic capacitors with tantalum capacitors. Ceramic capacitors constructed witht these dielectrics offer moderate dielectric constants with moderate temperature and voltage sensitivities. They overlap with tantalum capacitors in capacitance/voltage range offerings. In many cases, the solder pad geometry allows swapping of ceramic 0603. 0805, 1206 or 1210 chip sizes with “J”, “R”, “A”, or “B” case tantalums, respectively.
