Can small red beans be used instead of lentils in chili?

Small red beans and lentils have distinct textures and flavors, so substituting one for the other may not produce the desired result. Small red beans are larger than lentils and may require a different cooking time to achieve a similar softness. Additionally, red beans have a slightly sweet taste, while lentils have an earthy flavor. These differences could alter the overall taste of the chili. If you are looking for a bean that is similar to lentils in size and flavor, you could consider using split peas or mung beans.
