Substitute Part Grouping Explanation

Substitute parts for the BCP68-QX are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires that alternative parts maintain identical specifications in the following categories:

Electrical Parameters (Must Match):

• Transistor type: NPN
• Maximum collector current: 2 A
• Collector-emitter breakdown voltage: 20 V
• Vce saturation: 600 mV @ 200mA, 2A
• Collector cutoff current: 100 nA
• DC current gain (hFE): 85 minimum @ 500mA, 1V
• Maximum power dissipation: 650 mW
• Transition frequency: 170 MHz
• Maximum operating temperature: 150°C

Mechanical & Compliance Parameters (Must Match):

• Package type: SOT-223
• Mounting type: Surface Mount
• Automotive grade qualification: AEC-Q101
• RoHS compliance: ROHS3
• Moisture sensitivity level: 1 (Unlimited)

Parts meeting all specified parameters are classified as parametric equivalents and direct substitutes.
