BCV47QTC Equivalent & Substitute Parts

Part Overview

The BCV47QTC is an NPN Darlington bipolar junction transistor manufactured by Diodes Incorporated, designed for general-purpose switching and amplification applications. This surface-mount device is housed in a SOT-23-3 package and is qualified to automotive standards (AEC-Q101). The part is currently in active production status with 1034 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, supply chain continuity, or inventory optimization.

Substitute Part Grouping Explanation

Substitute parts for the BCV47QTC are identified based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

Electrical Parameters (Must Match):

• Transistor Type: NPN - Darlington
• Maximum Collector Current: 500 mA
• Collector-Emitter Breakdown Voltage: 60 V
• Vce Saturation: 1 V @ 100µA, 100mA
• Collector Cutoff Current: 100 nA
• DC Current Gain (hFE): 10000 @ 100mA, 5V
• Maximum Power Dissipation: 310 mW
• Transition Frequency: 170 MHz
• Operating Temperature Range: -55°C to 150°C

Mechanical Parameters (Must Match):

• Package Type: SOT-23-3 (TO-236-3, SC-59)
• Mounting Type: Surface Mount

Compliance & Certification (Must Match):

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

The BCV47QTA meets all specified criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the BCV47QTC and BCV47QTA are active production parts manufactured by Diodes Incorporated with identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain considerations:

BCV47QTC: 1034 units in stock. Suitable for immediate procurement requirements.

BCV47QTA: 5910 units in stock. Suitable for high-volume orders or long-term supply assurance. The higher inventory level provides greater availability for sustained production runs.

Both parts carry automotive-grade qualification (AEC-Q101) and are ROHS3 compliant, making them suitable for automotive and industrial applications requiring regulatory compliance. The identical electrical performance, power dissipation, frequency response, and temperature operating range ensure direct functional interchangeability in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can BCV47QTA be used as a direct replacement for BCV47QTC?

A: Yes. The BCV47QTA is a direct parametric equivalent with identical electrical specifications, power ratings, frequency response, and automotive qualification. Both parts are manufactured by Diodes Incorporated and housed in the same SOT-23-3 package.

Q: Are there any differences in the SOT-23-3 package between these parts?

A: No. Both parts use the identical SOT-23-3 package (also designated TO-236-3 or SC-59). Pin configuration, lead spacing, and mounting footprint are identical, requiring no PCB design modifications.

Q: Do both parts meet automotive standards?

A: Yes. Both the BCV47QTC and BCV47QTA are automotive-grade transistors qualified to AEC-Q101 standards, with operating temperature ranges of -55°C to 150°C and ROHS3 compliance.

Q: What is the difference between these part numbers?

A: The BCV47QTC and BCV47QTA are variant designations from Diodes Incorporated for the same device type. The difference is in the manufacturing date code or tape reel configuration, not in electrical or mechanical performance.

Q: Can I mix these parts in the same production batch?

A: Yes. Since both parts are electrically and mechanically identical with the same automotive qualification, they can be used interchangeably within the same design and production environment.

Q: What is the moisture sensitivity level for these transistors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control measures.

Q: Are these parts RoHS compliant?

A: Yes. Both the BCV47QTC and BCV47QTA are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements for electronic components.
