Key Parameters

Substitute Part Grouping Explanation

Substitute part grouping is strictly determined by the following parameters:

• Transistor configuration and type (2 NPN - Pre-Biased/Dual)
• Maximum collector current rating
• Maximum collector-emitter breakdown voltage
• Pre-biased resistor value
• DC current gain at specified conditions
• Maximum saturation voltage
• Cutoff current
• Transition frequency
• Maximum power dissipation
• Package compatibility (6-TSSOP, SC-88, SOT-363)
• Compliance (RoHS3)
• Moisture Sensitivity Level (MSL 1)

Substitution requires that all listed key parameters match between the main and substitute parts. No deviations from specified values are permitted in this category.
