Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2PB710ASL/ZLR is determined by the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Transistor Type: PNP configuration
• Collector Current (Ic Max): 500 mA
• Voltage - Collector Emitter Breakdown (Max): 45 V to 60 V range
• Power Dissipation (Max): 250 mW to 700 mW
• Mounting Type: Surface Mount
• Package / Case: TO-236-3, SC-59, or SOT-23-3 compatible footprints
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 (Unlimited)

Substitution Logic: All substitute parts listed maintain PNP transistor functionality with maximum collector current of 500 mA. Voltage ratings range from 45 V to 60 V, providing equal or superior voltage handling compared to the original part. All substitutes are surface mount devices in TO-236-3/SOT-23-3 package families, ensuring mechanical compatibility. All substitutes maintain ROHS3 compliance and MSL 1 rating, supporting identical environmental and regulatory requirements.

Engineering Selection Recommendations

Primary Recommendation: 2PB710ASL,215

The 2PB710ASL,215 manufactured by Nexperia USA Inc. is the manufacturer-recommended direct substitute. This part shares the same base product number (2PB710) and maintains identical compliance certifications (ROHS3, REACH Unaffected, MSL 1). The part is in active production status with 3862 units in stock. It provides 500 mA collector current and 50 V breakdown voltage with 250 mW power dissipation. AEC-Q101 automotive qualification is included. Packaging is TO-236AB in tape and reel format.

Secondary Recommendations:

BC807-40LT3G (onsemi) and BC807-16LT3G (onsemi) are active production alternatives with 45 V breakdown voltage, 500 mA collector current, and 300 mW power dissipation. Both maintain ROHS3 compliance and MSL 1 rating. BC807-40LT3G offers higher inventory availability (95300 units) and superior DC current gain (250 @ 100mA, 1V). BC807-16LT3G provides 100 MHz transition frequency with 30400 units available.

SBC807-25LT3G (onsemi) provides automotive-grade qualification (AEC-Q101) with 45 V breakdown voltage, 500 mA collector current, and 300 mW power dissipation. This part maintains ROHS3 compliance and MSL 1 rating with 6881 units in stock.

MMBTA55-7-F (Diodes Incorporated) offers the highest voltage rating at 60 V breakdown with 500 mA collector current and 300 mW power dissipation. Automotive-grade qualification (AEC-Q101) is included. This part maintains ROHS3 compliance and MSL 1 rating with 23400 units available.

50A02CH-TL-E (onsemi) provides the highest power dissipation at 700 mW and transition frequency at 690 MHz, supporting high-speed switching applications. Voltage rating is 50 V with 500 mA collector current. ROHS3 compliance and MSL 1 rating are maintained.

All substitute parts maintain surface mount configuration in TO-236-3/SOT-23-3 package families, ensuring mechanical compatibility with existing PCB layouts. Selection should be based on specific application requirements for voltage rating, power dissipation, frequency response, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can 2PB710ASL,215 directly replace 2PB710ASL/ZLR in all applications?

A: The 2PB710ASL,215 is the manufacturer-recommended substitute sharing the same base product number. Both parts are PNP transistors with 500 mA collector current, ROHS3 compliance, and MSL 1 rating. The primary difference is packaging format (tape and reel versus original format). Electrical performance is equivalent for standard switching and amplification applications.

Q: What is the difference between BC807-40LT3G and BC807-16LT3G?

A: Both parts are onsemi BC807 series PNP transistors with identical electrical ratings: 45 V breakdown voltage, 500 mA collector current, 300 mW power dissipation, and 100 MHz transition frequency. The primary difference is DC current gain specification: BC807-40LT3G specifies 250 @ 100mA, 1V while BC807-16LT3G specifies 100 @ 100mA, 1V. Selection depends on required current gain for the specific circuit design.

Q: Are automotive-qualified alternatives available?

A: Yes. SBC807-25LT3G (onsemi) and MMBTA55-7-F (Diodes Incorporated) both carry AEC-Q101 automotive qualification. Additionally, 2PB710ASL,215 (Nexperia) includes automotive-grade designation. These parts are suitable for automotive and industrial applications requiring qualification documentation.

Q: What is the voltage rating difference between substitute parts?

A: Substitute parts offer three voltage rating options: 45 V (BC807-16LT3G, BC807-40LT3G, SBC807-25LT3G), 50 V (2PB710ASL,215, 50A02CH-TL-E), and 60 V (MMBTA55-7-F). Selection should match or exceed the original circuit voltage requirements. Higher voltage-rated parts provide additional design margin but do not affect lower-voltage applications.

Q: Which substitute offers the highest power dissipation capability?

A: The 50A02CH-TL-E (onsemi) provides 700 mW maximum power dissipation, compared to 250-300 mW for other substitutes. This part is suitable for applications requiring higher power handling or continuous operation at elevated current levels. It also offers the highest transition frequency at 690 MHz for high-speed switching applications.

Q: Are all substitutes available in surface mount packaging?

A: Yes. All substitute parts are surface mount devices in TO-236-3, SC-59, or SOT-23-3 package families. These packages are mechanically compatible with standard PCB layouts designed for the original 2PB710ASL/ZLR component. No PCB redesign is required for package compatibility.

Q: What is the significance of MSL 1 rating for all parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All listed parts, including the original and all substitutes, maintain this rating. This simplifies inventory management and eliminates moisture-related handling procedures for storage and assembly.

Q: Can I use MMBTA55-7-F as a universal replacement?

A: MMBTA55-7-F can serve as a universal replacement in most applications due to its 60 V voltage rating, which exceeds all other substitutes. However, it offers lower transition frequency (50 MHz) compared to other options. For high-frequency switching applications, BC807 series or 50A02CH-TL-E would be more appropriate selections.
