A contactor uses a pogo block in a first configuration as a direct integrated circuit test socket and the contactor can be reconfigured to provide a pogo block assembly to interface between a main test printed circuit board (PCB) and a daughter card that is dedicated to a specific device handler and/or a specific package type that can be different from the main test PCB. A pogo block is inserted into a thick frame with an alignment plate for contactor use in which a device under test fits into a recess in the frame through an alignment plate to align the device under test to make contact with electrical contacts of the contactor. The frame and guide plate can be removed and a thinner frame coupled to the contactor, which changes its function to a pogo block assembly.
