For a substitution vector-valued integral operator T ϕ u , we determine necessary and sufficient conditions to have Hyers-Ulam stability using conditional expectation operators. Then, we present an example to illustrate our result. Definition 1.1 ([9] ). Let X, Y be normed linear spaces and T be a (not necessarily linear) mapping from X into Y . We say that T has the Hyers-Ulam stability if there exists a constant M > 0 with the following property: For any ∈ T(X), > 0 and f ∈ T(X) satisfying T
