Key Parameters

Substitute Part Grouping Explanation

The substitute part for 2SC4095-A, specifically BFU520VL, is selected strictly based on compliance with the following key parameters: transistor NPN type, category (Transistors, Bipolar (BJT)), collector-emitter breakdown voltage, transition frequency, noise figure, gain, maximum collector current, maximum power, DC current gain, operating temperature, mounting type, and package compatibility. Substitution is determined by explicit alignment across these defined parameters and package formats relevant to RF surface-mount applications.

Parameter Comparison

Engineering Selection Recommendations

Selection should be based on matching critical compliance parameters, including electrical ratings, mechanical compatibility, and regulatory certifications. Both the 2SC4095-A and BFU520VL meet category, transistor type, mounting type, package compatibility, MSL rating, REACH status, and ECCN/HTSUS classifications. The BFU520VL currently holds an active status and is ROHS3 compliant, whereas the 2SC4095-A is obsolete, supporting preference for substitution where continued supply and compliance are required.
