Replacing the transistor with one that has a different $f_{idc}$ (forward current transfer ratio in common base) would primarily affect the collector current ($I_C$) due to changes in the transistor's amplification characteristics. However, since $V_C$ (collector voltage) is determined by the collector current and the load in the collector circuit, a change in $f_{idc}$ would only slightly adjust $V_C$, assuming all other components and supply voltages remain constant. The effect is not drastic because the circuit's design, including resistor values and supply voltage, limits the range of possible $V_C$ values.
