Substitute Part Grouping Explanation
Substitute parts for the 2PB709ASL,235 are classified into two categories based on electrical and mechanical compatibility:
Parametric Equivalents share identical electrical specifications, including collector current (100 mA), collector-emitter breakdown voltage (45 V), saturation voltage, DC current gain, transition frequency (80 MHz), and power dissipation (250 mW). These parts differ only in packaging format or manufacturer part number variant. Parametric equivalents are direct functional replacements with no circuit redesign required.
Similar Parts maintain the same transistor type (PNP), package family (SOT-23-3), and collector-emitter breakdown voltage (45 V), but feature enhanced maximum collector current (500 mA) and power dissipation (300–310 mW). These parts operate at higher transition frequencies (100 MHz) and support extended operating temperature ranges. Similar parts are suitable for applications where the 2PB709ASL,235 specifications are met with margin, or where higher current capability is beneficial.
The key parameters determining substitution eligibility are:
- Transistor type (PNP)
- Collector-emitter breakdown voltage (45 V minimum)
- Surface mount package compatibility (SOT-23-3 / TO-236)
- Automotive grade and AEC-Q101 qualification (where required)
- RoHS3 compliance

Engineering Selection Recommendations
Parametric Equivalent Selection
The parts 2PB709ASL,215 and 2PB709ASL-QVL are direct parametric equivalents to the 2PB709ASL,235. All three components are manufactured by Nexperia USA Inc., carry automotive grade qualification, and meet AEC-Q101 standards. These parts are interchangeable at the circuit level with no performance degradation. Selection among these three variants depends on packaging format availability: 2PB709ASL,235 and 2PB709ASL,215 are supplied in Tape & Reel format, while 2PB709ASL-QVL is available in Cut Tape & Digi-Reel format.
Similar Part Selection
The BC807 series parts (BC807-16-7-F, BC807-16LT1G, BC807-16LT3G, BC807-25-TP, BC807-25LT1G, BC807-25LT3G, BC807-40-7-F, BC807-40-TP) are similar alternatives that maintain the 45 V collector-emitter breakdown voltage and SOT-23-3 package compatibility. These parts feature five times higher maximum collector current (500 mA versus 100 mA) and higher transition frequency (100 MHz versus 80 MHz). The BC807 series does not carry automotive grade or AEC-Q101 qualification.
Selection of BC807 variants is appropriate for non-automotive applications or where the enhanced current and frequency specifications provide design margin. The choice among BC807 variants depends on DC current gain requirements: BC807-16 variants provide hFE of 100, BC807-25 variants provide hFE of 160, and BC807-40 variants provide hFE of 250. Manufacturer selection (Diodes Incorporated, onsemi, or Micro Commercial Co) and packaging format (Tape & Reel or Cut Tape & Digi-Reel) determine final part number selection.
Frequently Asked Questions (FAQ)
Q: Can 2PB709ASL,215 be used as a direct replacement for 2PB709ASL,235?
A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, including 100 mA maximum collector current, 45 V collector-emitter breakdown voltage, 250 mW power dissipation, and 80 MHz transition frequency. The difference is packaging format: 2PB709ASL,235 uses Tape & Reel format with part number suffix ",235," while 2PB709ASL,215 uses Tape & Reel format with suffix ",215." Both are AEC-Q101 qualified automotive grade components.
Q: What is the difference between 2PB709ASL-QVL and 2PB709ASL,235?
A: Both parts are parametric equivalents with identical electrical performance. The primary difference is packaging: 2PB709ASL-QVL is supplied in Cut Tape & Digi-Reel format, while 2PB709ASL,235 is supplied in standard Tape & Reel format. Electrical specifications, automotive qualification, and AEC-Q101 compliance are identical.
Q: Can BC807 series parts replace the 2PB709ASL,235?
A: BC807 series parts maintain the same 45 V collector-emitter breakdown voltage and SOT-23-3 package, making them mechanically and electrically compatible at the package level. However, BC807 parts feature 500 mA maximum collector current compared to 100 mA for the 2PB709ASL,235. BC807 parts do not carry automotive grade or AEC-Q101 qualification. Use BC807 parts only in non-automotive applications or where higher current capability is required and automotive qualification is not mandated.
Q: What is the difference between BC807-16, BC807-25, and BC807-40 variants?
A: The numeric suffix indicates the DC current gain (hFE) specification. BC807-16 variants specify minimum hFE of 100 at 100 mA collector current and 1 V collector-emitter voltage. BC807-25 variants specify minimum hFE of 160. BC807-40 variants specify minimum hFE of 250. All three variants share identical maximum collector current (500 mA), collector-emitter breakdown voltage (45 V), and transition frequency (100 MHz). Selection depends on circuit requirements for current gain.
Q: Are all substitute parts RoHS3 compliant?
A: Yes. The 2PB709ASL,235 and all listed parametric equivalents (2PB709ASL,215 and 2PB709ASL-QVL) are ROHS3 compliant. The BC807 series similar parts are also ROHS3 compliant. All parts listed in this reference meet RoHS3 requirements.
Q: What packaging formats are available for the 2PB709ASL,235 and equivalents?
A: The 2PB709ASL,235 and 2PB709ASL,215 are supplied in Tape & Reel (TR) format. The 2PB709ASL-QVL is supplied in Cut Tape (CT) & Digi-Reel format. All three use the SOT-23-3 (TO-236AB) surface mount package. BC807 series parts are available in both Tape & Reel and Cut Tape & Digi-Reel formats depending on the specific variant.
Q: Is the 2PB709ASL,235 suitable for automotive applications?
A: Yes. The 2PB709ASL,235 carries automotive grade qualification and meets AEC-Q101 standards. It is suitable for automotive circuit applications. The BC807 series parts do not carry automotive grade or AEC-Q101 qualification and are not recommended for automotive applications.
Q: What is the maximum operating temperature for the 2PB709ASL,235?
A: The maximum junction temperature (TJ) is 150°C. The BC807 series parts support an extended operating temperature range of −55°C to 150°C.
