(Transition Frequency): For RF or high-speed switching, the replacement frequency must be equal to or higher than the original. 5. Package Style (Physical Dimensions)
This indicates how much heat the transistor can safely dissipate. The replacement must have an equal or higher wattage rating, especially in power amplifier and power supply circuits. 5. Current Gain ( hFEh sub cap F cap E end-sub all type transistor equivalent pdf
) : The transition frequency should meet or slightly exceed the original. Avoid significantly higher fTf sub cap T in some circuits as it can cause unwanted oscillations . (Transition Frequency): For RF or high-speed switching, the
