There is provided a device-dependent replaceable unit for use with a test apparatus, which can reduce signal deterioration. The device-dependent replaceable unit is selected depending on a type of a device under test, and to be mounted on the test apparatus to form a signal path between the device under test and the test apparatus. The device-dependent replaceable unit includes a socket board that has a front surface and a back surface, where the device under test is to be moved close to or away from the front surface of the socket board, and a plurality of spring pins that are positioned in a same manner as a plurality of connection terminals of the device under test, where the spring pins are supported by the socket board in such a manner that upper ends of the spring pins protrude from the front surface of the socket board and come into contact with the connection terminals of the device under test.
