Key Parameters

Substitute Part Grouping Explanation

Substitution of the BC847CQCZ is determined by electrical and mechanical parameter equivalence within the NPN bipolar junction transistor category. The following parameters establish the substitution criteria:

Electrical Parameters (Critical for Functional Equivalence):

• Maximum collector current: 100 mA
• Maximum collector-emitter breakdown voltage: 45 V
• Vce saturation: 400 mV @ 5 mA, 100 mA
• DC current gain (hFE): 420 (minimum) @ 2 mA, 5 V
• Maximum power dissipation: 360 mW
• Transition frequency: 100 MHz
• Collector cutoff current: 15 nA (ICBO)
• Operating temperature: 150°C (TJ)

Mechanical Parameters (Critical for Physical Compatibility):

• Package type: 3-XDFN Exposed Pad
• Supplier device package: DFN1412D-3
• Mounting type: Surface Mount, Wettable Flank

Compliance Parameters:

• RoHS3 compliance
• REACH unaffected status

Substitute parts must match all electrical and mechanical parameters listed above to ensure direct functional and physical compatibility without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

The BC847CQC-QZ is a direct electrical and mechanical equivalent to the BC847CQCZ. Both parts share identical electrical specifications across all critical parameters: collector current, breakdown voltage, saturation voltage, current gain, power dissipation, transition frequency, and operating temperature range. Both parts utilize the same 3-XDFN Exposed Pad package (DFN1412D-3) with wettable flanks and surface mount configuration, ensuring compatibility with existing printed circuit board layouts and assembly processes.

The primary distinction between the two parts is product status. The BC847CQCZ is classified as Obsolete, while the BC847CQC-QZ is classified as Active. The BC847CQC-QZ is supplied in Tape & Reel (TR) packaging, which is the standard format for high-volume production environments.

The BC847CQC-QZ carries additional qualifications not specified for the BC847CQCZ: Automotive grade designation and AEC-Q100 qualification. These certifications indicate compliance with automotive industry reliability and quality standards. The BC847CQC-QZ also carries a higher Moisture Sensitivity Level (MSL 3, 168 hours) compared to the BC847CQCZ (MSL 1, Unlimited). Both parts maintain ROHS3 compliance and REACH unaffected status.

For applications requiring continued supply and production support, the BC847CQC-QZ is the appropriate selection. The part is currently in active production with substantial inventory availability (5912 pieces in stock) and provides equivalent electrical performance with enhanced qualification credentials.

Frequently Asked Questions (FAQ)

Q: Can the BC847CQC-QZ be used as a direct replacement for the BC847CQCZ in existing designs?

A: Yes. The BC847CQC-QZ is electrically and mechanically equivalent to the BC847CQCZ. All critical electrical parameters—collector current, breakdown voltage, saturation voltage, current gain, power dissipation, and transition frequency—are identical. Both parts use the same 3-XDFN Exposed Pad package (DFN1412D-3) with wettable flanks. No circuit redesign or board layout modification is required.

Q: What is the significance of the Obsolete status for the BC847CQCZ?

A: Obsolete status indicates that the BC847CQCZ is no longer in active production and will not be manufactured in the future. This status necessitates identification of an active equivalent part to ensure continued supply chain reliability and support for ongoing production. The BC847CQC-QZ fulfills this requirement.

Q: Are there differences in packaging between the BC847CQCZ and BC847CQC-QZ?

A: Both parts use the same 3-XDFN Exposed Pad package (DFN1412D-3). The BC847CQC-QZ is supplied in Tape & Reel (TR) format, which is the standard packaging for production environments. The BC847CQCZ packaging format is not specified in the available data.

Q: What does the Automotive grade and AEC-Q100 qualification on the BC847CQC-QZ indicate?

A: Automotive grade designation and AEC-Q100 qualification indicate that the BC847CQC-QZ meets automotive industry reliability, quality, and testing standards. These certifications are not specified for the BC847CQCZ. For applications in automotive environments, the BC847CQC-QZ provides verified compliance with automotive qualification requirements.

Q: How does the Moisture Sensitivity Level (MSL) difference affect part selection?

A: The BC847CQCZ carries MSL 1 (Unlimited), while the BC847CQC-QZ carries MSL 3 (168 hours). MSL 3 indicates that the part must be used within 168 hours of package opening if stored in standard conditions. For applications with extended storage or humid environments, MSL 1 parts require less stringent moisture control. However, both parts are suitable for standard production environments with appropriate moisture management protocols.

Q: Is the BC847CQC-QZ available in sufficient quantity for production?

A: Yes. The BC847CQC-QZ has 5912 pieces in current stock, providing substantial availability for production requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the BC847CQCZ and BC847CQC-QZ are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for electronic components.
