2SC2812N6-CPA-TB-E Equivalent & Substitute Parts

Part Overview

The 2SC2812N6-CPA-TB-E is an NPN bipolar junction transistor manufactured by onsemi, rated for 50 V collector-emitter breakdown voltage and 150 mA maximum collector current. This surface mount device in TO-236-3 (SOT-23-3) package is designed for general-purpose switching and amplification applications with a maximum power dissipation of 200 mW and transition frequency of 100 MHz.

The 2SC2812N6-CPA-TB-E is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production, repair, and redesign applications. Substitute transistors must maintain electrical compatibility within the specified parameter ranges while meeting the same mechanical and thermal requirements.

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended Primary Substitutes):

The MMBT6428LT1G and 2DC2412R-7 provide direct electrical compatibility with the 2SC2812N6-CPA-TB-E. Both devices maintain the 50 V collector-emitter breakdown voltage and support the required 150 mA collector current. The MMBT6428LT1G offers enhanced performance with 700 MHz transition frequency and 225 mW power dissipation, while the 2DC2412R-7 provides 300 mW power dissipation with 180 MHz transition frequency. Both are active products with current manufacturing status and RoHS3 compliance.

Current-Limited Substitutes (Conditional Use):

The 2PD601 series devices (2PD601ARL,215; 2PD601ART,215; 2PD601ASL,215; 2PD601ASL,235; 2PD601ARL,235; 2PD601ART,235) are rated for 100 mA maximum collector current, which is below the 150 mA specification of the 2SC2812N6-CPA-TB-E. These parts are suitable only for applications where the actual circuit current requirement does not exceed 100 mA. All 2PD601 variants are automotive-grade devices with AEC-Q101 qualification and active product status.

Enhanced Performance Substitutes (Higher Current Capability):

The 2PD601BRL,215 and 2PD601BSL,215 devices support 200 mA collector current, exceeding the 150 mA requirement of the original part. These devices feature 250 MHz transition frequency and are automotive-qualified with AEC-Q101 certification. Both are active products suitable for applications requiring higher current handling capability.

Compliance Status:

All substitute parts maintain REACH Unaffected status and EAR99 ECCN classification consistent with the original 2SC2812N6-CPA-TB-E. Moisture sensitivity level remains at 1 (Unlimited) across all alternatives.

Frequently Asked Questions (FAQ)

Q: Can the MMBT6428LT1G directly replace the 2SC2812N6-CPA-TB-E?

A: Yes. The MMBT6428LT1G meets or exceeds all critical electrical parameters: 50 V collector-emitter breakdown voltage, 200 mA maximum collector current (exceeds 150 mA requirement), 225 mW power dissipation (exceeds 200 mW requirement), and 700 MHz transition frequency (exceeds 100 MHz requirement). Both devices use the same TO-236-3 (SOT-23-3) package and surface mount configuration. The MMBT6428LT1G is an active product with current manufacturing availability.

Q: What is the difference between 2PD601 variants with different suffixes (ARL, ART, ASL, BRL, BSL)?

A: The suffix designations indicate different electrical grades and current ratings within the 2PD601 family. The "A" variants are rated for 100 mA maximum collector current, while "B" variants support 200 mA. The letter following the grade (R, S) and the final digits (L, T) indicate packaging configuration and manufacturing date codes. All variants maintain the same 50 V collector-emitter breakdown voltage and TO-236AB package.

Q: Are the 2PD601 series devices suitable for all applications using the 2SC2812N6-CPA-TB-E?

A: The 2PD601A series (100 mA rating) is suitable only for applications where actual collector current does not exceed 100 mA. The 2PD601B series (200 mA rating) is suitable for applications requiring up to 150 mA. All 2PD601 variants are automotive-qualified with AEC-Q101 certification, making them suitable for automotive and industrial applications. Verify circuit current requirements before selection.

Q: What is the advantage of the 2DC2412R-7 over the 2SC2812N6-CPA-TB-E?

A: The 2DC2412R-7 provides 300 mW maximum power dissipation compared to 200 mW for the original part, offering improved thermal headroom. It maintains the same 150 mA collector current rating and 50 V breakdown voltage. The 2DC2412R-7 features 180 MHz transition frequency and is manufactured by Diodes Incorporated with active product status and RoHS3 compliance.

Q: Can I use a substitute part with lower maximum collector current than the original specification?

A: Only if your circuit design operates below the substitute part's maximum rating. For example, 2PD601A series devices rated for 100 mA can replace the 2SC2812N6-CPA-TB-E in circuits where actual collector current does not exceed 100 mA. Circuit analysis is required to confirm safe operation within the substitute part's electrical limits.

Q: Are all substitute parts available in the same package as the 2SC2812N6-CPA-TB-E?

A: All substitute parts use the TO-236-3, SC-59, or SOT-23-3 package designation, which are mechanically and electrically equivalent. These packages are interchangeable for PCB layout and soldering purposes. Verify specific supplier device package designations (such as SOT-23-3 or TO-236AB) match your assembly requirements.

Q: What compliance certifications should I verify when selecting a substitute?

A: All listed substitute parts maintain REACH Unaffected status and EAR99 ECCN classification. The 2PD601 series devices include AEC-Q101 automotive qualification. Verify RoHS compliance status for your specific application requirements. The MMBT6428LT1G and 2DC2412R-7 are RoHS3 compliant.
