Substitute Part Grouping Explanation

Substitution logic is strictly based on the following key parameters: transistor type, maximum collector current (Ic), maximum collector-emitter breakdown voltage (Vce), maximum saturation voltage (Vce(sat)), maximum collector cutoff current, minimum DC current gain (hFE), maximum power dissipation, transition frequency, operating temperature range, mounting type, and package compatibility. Substitute parts must match or exceed the functional performance and mechanical compatibility defined by these parameters.

Engineering Selection Recommendations

Engineering selection should be based on the product status (Active or Last Time Buy), compliance attributes such as RoHS and REACH, and relevant industry or automotive qualification when specified. All listed substitutes conform to the provided environmental and operational compliance statuses. Selection among active parts is permissible for direct functional substitution. Last Time Buy status may affect long-term availability, requiring inventory assessment.
