In this article, the class of all Dunford–Pettis p-convergent operators and p-Dunford–Pettis relatively compact property on Banach spaces are investigated. Moreover, we give some conditions on Banach spaces X and Y such that the class of bounded linear operators from X to Y and some its subspaces have the p-Dunford–Pettis relatively compact property. In addition, if \( \Omega \) is a compact Hausdorff space, then we prove that dominated operators from the space of all continuous functions from K to Banach space X (in short \( C(\Omega ,X) \)) taking values in a Banach space with the p-(DPrcP) are p-convergent when X has the Dunford–Pettis property of order p. Furthermore, we show that if \( T:C(\Omega ,X)\rightarrow Y \) is a strongly bounded operator with representing measure \( m:\Sigma \rightarrow L(X,Y) \) and \( \hat{T}:B(\Omega ,X)\rightarrow Y \) is its extension, then T is Dunford–Pettis p-convergent if and only if \( \hat{T}\) is Dunford–Pettis p-convergent.
