Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on electrical and mechanical parameter alignment with the BC807K-40R:

Parametric Equivalents share identical electrical specifications across all critical parameters: 500 mA collector current, 45 V breakdown voltage, 250 mW power rating, 80 MHz transition frequency, 700 mV saturation voltage at specified bias conditions, and 250 minimum DC current gain. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or minor device code variations that do not affect circuit performance. Parametric equivalents include BC807-40,215; BC807-40,235; BC807-40LR; BC807-40LVL; BC807-40LZ; and BC807K-40VL.

Similar Parts maintain compatibility in collector current (500 mA), collector-emitter breakdown voltage (45 V or higher), package form factor (TO-236-3, SOT-23-3), and surface mount technology. However, these parts exhibit variations in one or more secondary parameters such as transition frequency, power dissipation, saturation voltage, or DC current gain. Similar parts include 2SA1313-Y,LF (Toshiba), BC807-16LT1G (onsemi), and SBC807-40LT3G (onsemi).

Substitution eligibility is determined by:

Transistor type (PNP)
Collector current rating (500 mA minimum)
Collector-emitter breakdown voltage (45 V minimum)
Package compatibility (TO-236-3, SOT-23-3)
Surface mount mounting type
RoHS3 compliance

Engineering Selection Recommendations

Parametric Equivalent Selection: Parts BC807-40,215; BC807-40,235; BC807-40LR; BC807-40LVL; BC807-40LZ; and BC807K-40VL are direct parametric equivalents of the BC807K-40R. All maintain identical electrical performance across collector current, breakdown voltage, power dissipation, transition frequency, and saturation characteristics. These parts are manufactured by Nexperia USA Inc. and carry AEC-Q100 or AEC-Q101 automotive qualification. Selection among these equivalents is based on packaging format availability (Cut Tape vs. Tape & Reel) and inventory requirements. All are RoHS3 compliant with MSL 1 rating.

Similar Part Considerations: The onsemi SBC807-40LT3G maintains full electrical equivalence to the BC807K-40R with identical hFE and saturation voltage specifications. This part carries AEC-Q101 automotive qualification and offers increased power dissipation (300 mW vs. 250 mW) and higher transition frequency (100 MHz vs. 80 MHz), providing performance margin in switching applications. The onsemi BC807-16LT1G shares the same package and electrical ratings but exhibits lower DC current gain (100 vs. 250), requiring circuit design verification for bias network compatibility.

The Toshiba 2SA1313-Y,LF operates at 50 V breakdown voltage (5 V margin above BC807K-40R) and 200 MHz transition frequency. However, this part exhibits significantly lower DC current gain (120 vs. 250) and reduced saturation voltage (250 mV vs. 700 mV), necessitating circuit redesign for bias and switching characteristics. This part lacks automotive qualification documentation.

Compliance and Certification: All Nexperia parametric equivalents maintain AEC-Q100 or AEC-Q101 qualification suitable for automotive applications. The onsemi SBC807-40LT3G carries AEC-Q101 qualification. All substitute parts are RoHS3 compliant and REACH unaffected. Moisture sensitivity level remains MSL 1 (unlimited) across all options.

Frequently Asked Questions (FAQ)

Q: Can BC807-40,215 replace BC807K-40R in production?

A: Yes. BC807-40,215 is a parametric equivalent with identical electrical specifications. The difference is packaging format: BC807-40,215 is supplied in Cut Tape & Digi-Reel format while BC807K-40R is Tape & Reel. Both are AEC-Q100/Q101 qualified and RoHS3 compliant. Selection depends on assembly equipment compatibility and inventory management.

Q: What is the difference between BC807-40LR and BC807-40LZ?

A: Both parts are parametric equivalents with identical electrical performance. The suffix designations (LR vs. LZ) indicate different packaging or tape configuration codes from Nexperia. Electrical characteristics, power rating, frequency response, and gain specifications are identical. Selection is based on supplier availability and tape reel specifications.

Q: Can SBC807-40LT3G be used instead of BC807K-40R?

A: Yes, with performance margin. SBC807-40LT3G is manufactured by onsemi and maintains identical collector current (500 mA), breakdown voltage (45 V), saturation voltage (700 mV @ 50 mA, 500 mA), and DC current gain (250 @ 100 mA, 1 V). The part offers higher power dissipation (300 mW vs. 250 mW) and faster transition frequency (100 MHz vs. 80 MHz). AEC-Q101 automotive qualification is provided. Direct substitution is supported.

Q: Why does BC807-16LT1G have lower hFE than BC807K-40R?

A: BC807-16LT1G is a similar part from onsemi with DC current gain of 100 minimum at 100 mA, 1 V, compared to 250 for BC807K-40R. This reflects different device design and manufacturing process. Lower gain requires higher base current for equivalent collector current, affecting bias resistor selection. Circuit redesign is necessary if base drive is current-limited.

Q: Is 2SA1313-Y,LF suitable for automotive applications?

A: 2SA1313-Y,LF is a Toshiba PNP transistor with compatible package and collector current rating. However, this part lacks documented automotive qualification (AEC-Q100/Q101). Additionally, DC current gain is 120 (vs. 250 for BC807K-40R) and saturation voltage is 250 mV (vs. 700 mV), requiring circuit verification. Use in automotive applications requires qualification assessment.

Q: What does AEC-Q100 vs. AEC-Q101 qualification mean?

A: AEC-Q100 and AEC-Q101 are automotive electronics council reliability qualification standards. AEC-Q100 applies to discrete semiconductors; AEC-Q101 applies to optoelectronic devices. Both certifications indicate the part meets automotive temperature cycling, thermal shock, and reliability testing requirements. BC807K-40R carries AEC-Q100; most substitute parts carry AEC-Q101. Both are acceptable for automotive use.

Q: Can I mix BC807K-40R and BC807-40,235 in the same circuit board?

A: Yes. Both parts are parametric equivalents with identical electrical specifications. Mixing is supported from an electrical standpoint. However, manufacturing and supply chain practices typically standardize on a single part number per design to simplify procurement, inventory management, and traceability.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. All listed substitute parts carry MSL 1 rating, eliminating moisture-related reliability concerns and simplifying logistics.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance certification. This confirms lead-free construction and compliance with restricted substance directives. All parts are also REACH unaffected, indicating no substances of very high concern are present.
