Let $G$ be a finite group. Based on the Gruenberg-Kegel graph $GK(G)$, the order of G can be divided into a product of coprime positive integers. These integers are called the order components of $G$ and the set of order components is denoted by $OC(G)$. In this article we prove that, if $S$ is a non-Abelian finite simple group with a disconnected graph $GK(S)$, with an exception of $U_{4}(2)$ and $U_5(2)$, and $G$ is a finite group with $OC(G) = OC(S)$, then $G$ is neither Frobenius nor $2$-Frobenius. For a group $S$ isomorphic to $U_{4}(2)$ or $U_{5}(2)$, we construct examples of $2$-Frobenius groups $G$ such that $OC(S) = OC(G)$. In particular, the simple groups $U_{4}(2)$ and $U_{5}(2)$ are not recognizable by their order components.
