Substitute Part Grouping Explanation
Substitute parts for the BC807K-25R are classified into two categories based on electrical and mechanical compatibility:
Parametric Equivalents maintain identical electrical specifications across all critical parameters: 45 V collector-emitter breakdown voltage, 500 mA maximum collector current, 700 mV Vce saturation, 160 mA minimum DC current gain, 250 mW power dissipation, and 80 MHz transition frequency. These parts differ only in packaging format (Cut Tape vs. Tape & Reel) or minor manufacturing code variations. Parametric equivalents include BC807-25,215; BC807-25,235; BC807-25LR; BC807-25LVL; and BC807-25LZ, all manufactured by Nexperia USA Inc.
Similar Parts share the same transistor type, voltage rating, and current rating but exhibit variations in one or more secondary electrical parameters. These variations include higher power dissipation (300 mW vs. 250 mW), higher transition frequency (100 MHz vs. 80 MHz), or different DC current gain specifications. Similar parts include BC807-16LT1G and BC807-40LT3G from onsemi, and BC807-25-TP from Micro Commercial Co. These parts are functionally compatible in most applications but require verification of specific circuit requirements before substitution.
The key parameters determining substitution eligibility are: transistor type (PNP), collector-emitter breakdown voltage (45 V), maximum collector current (500 mA), Vce saturation characteristics, DC current gain, power dissipation rating, and package compatibility (TO-236-3/SOT-23-3 surface mount).

Engineering Selection Recommendations
For Direct Substitution (Parametric Equivalents):
The Nexperia USA Inc. parts BC807-25,235, BC807-25LR, BC807-25LVL, and BC807-25LZ are direct parametric equivalents to the BC807K-25R. These parts maintain identical electrical specifications and are suitable for one-to-one replacement in existing designs. The primary difference is packaging format: BC807-25,215 is supplied in Cut Tape & Digi-Reel® format, while BC807-25,235, BC807-25LR, BC807-25LVL, and BC807-25LZ are supplied in Tape & Reel format. All Nexperia equivalents carry AEC-Q100 or AEC-Q101 automotive qualification and ROHS3 compliance, meeting the same regulatory requirements as the primary part.
BC807K-25VL is also a direct parametric equivalent from Nexperia USA Inc. with AEC-Q100 qualification and identical electrical performance.
For Similar Substitution (With Parameter Variations):
The onsemi BC807-16LT1G and BC807-40LT3G, and the Micro Commercial Co BC807-25-TP are functionally compatible alternatives with the following considerations:
BC807-16LT1G exhibits a lower minimum DC current gain (100 vs. 160) but offers higher power dissipation (300 mW vs. 250 mW) and higher transition frequency (100 MHz vs. 80 MHz). This part is suitable for applications where higher frequency response is beneficial and lower current gain is acceptable.
BC807-40LT3G provides the highest DC current gain (250 vs. 160) with 300 mW power dissipation and 100 MHz transition frequency. This part is appropriate for applications requiring higher current amplification.
BC807-25-TP from Micro Commercial Co maintains the same DC current gain (160) as the primary part but offers 300 mW power dissipation and 100 MHz transition frequency. This part provides enhanced thermal and frequency performance while preserving current gain characteristics.
All substitute parts maintain the same TO-236-3/SOT-23-3 surface mount package, ensuring mechanical and footprint compatibility.
Frequently Asked Questions (FAQ)
Q: Can BC807-25,235 be used as a direct replacement for BC807K-25R?
A: Yes. BC807-25,235 is a parametric equivalent with identical electrical specifications: 45 V breakdown voltage, 500 mA collector current, 700 mV Vce saturation, 160 mA minimum DC current gain, 250 mW power dissipation, and 80 MHz transition frequency. The primary difference is packaging format (Tape & Reel vs. the original Tape & Reel). Both parts carry automotive qualification and ROHS3 compliance.
Q: What is the difference between BC807-25LR and BC807-25LVL?
A: BC807-25LR and BC807-25LVL are parametric equivalents with identical electrical specifications. Both are manufactured by Nexperia USA Inc., carry AEC-Q101 qualification, and are supplied in Tape & Reel format. The difference lies in manufacturing code variations and inventory levels. Both are suitable for direct substitution.
Q: Can I substitute BC807-40LT3G for BC807K-25R?
A: BC807-40LT3G is a similar part with compatible voltage and current ratings but differs in DC current gain (250 vs. 160) and offers higher power dissipation (300 mW vs. 250 mW) and transition frequency (100 MHz vs. 80 MHz). This part is functionally compatible in most applications. The higher current gain may provide improved switching characteristics in some circuits, but circuit-specific verification is necessary if current gain is a critical design parameter.
Q: Are all substitute parts in the same package?
A: Yes. All substitute parts listed are supplied in TO-236-3, SC-59, or SOT-23-3 surface mount packages, ensuring mechanical and PCB footprint compatibility with the BC807K-25R.
Q: What is the difference between Cut Tape and Tape & Reel packaging?
A: Cut Tape (CT) & Digi-Reel® packaging is suitable for manual assembly and smaller production runs, while Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment. Both formats contain the same component; the difference is in the delivery and handling format. Selection depends on manufacturing process requirements.
Q: Do all substitute parts meet automotive qualification standards?
A: Nexperia USA Inc. parts (BC807-25,215; BC807-25,235; BC807-25LR; BC807-25LVL; BC807-25LZ; BC807K-25VL) carry AEC-Q100 or AEC-Q101 automotive qualification. The onsemi and Micro Commercial Co parts do not specify automotive qualification in the provided data. For applications requiring automotive-grade components, Nexperia equivalents are recommended.
Q: What is the significance of the "K" designation in BC807K-25R?
A: The "K" designation indicates a specific manufacturing variant or grade level within the BC807 family. Equivalent parts with different designations (such as BC807-25LR or BC807-25LZ) maintain the same electrical specifications but may have different manufacturing codes or qualification levels.
Q: Can I use BC807-16LT1G if my circuit requires lower current gain?
A: BC807-16LT1G has a minimum DC current gain of 100 compared to 160 for the BC807K-25R. This part is suitable only if your circuit design accommodates the lower current gain specification. If current gain is a critical parameter for circuit operation, this substitution requires circuit analysis and testing.
