Substitute Part Grouping Explanation

Substitute parts for the BC807-40HZ are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents share identical or functionally equivalent electrical specifications across all critical parameters: collector current (500 mA), collector-emitter breakdown voltage (45 V), Vce saturation characteristics, DC current gain, power dissipation, and package type (TO-236-3 / SOT-23-3). These parts are direct functional replacements with no circuit redesign required.

Similar Parts maintain compatibility in core parameters (transistor type, collector current, breakdown voltage, package family) but differ in one or more secondary parameters such as transition frequency, power dissipation, DC current gain, or operating temperature range. These parts are suitable for applications where the specified parameter differences do not impact circuit performance.

Substitution eligibility is determined by the following key parameters:

Transistor Type: PNP
Collector Current (Max): 500 mA
Collector-Emitter Breakdown Voltage (Max): 45 V or higher
Package Type: TO-236-3 / SOT-23-3 surface mount
Vce Saturation characteristics within acceptable range
RoHS3 compliance and MSL-1 moisture sensitivity

Engineering Selection Recommendations

Parametric Equivalent Selection:

BC807-40HR and BC807-40HVL are parametric equivalents of BC807-40HZ. Both parts are manufactured by Nexperia USA Inc., carry automotive grade designation, and hold AEC-Q101 qualification. All three parts share identical electrical specifications for collector current, breakdown voltage, Vce saturation, DC current gain, power dissipation, and transition frequency. These parts are direct functional replacements suitable for any application currently using BC807-40HZ without circuit modification.

Similar Part Selection:

SBC807-40LT1G (onsemi) is an automotive-qualified alternative with identical Vce saturation and DC current gain characteristics. It differs in power dissipation (300 mW vs. 320 mW) and transition frequency (100 MHz vs. 80 MHz), with a reduced maximum operating temperature (150°C vs. 175°C). This part is suitable for applications where the higher transition frequency and lower power dissipation are acceptable trade-offs.

BC807-40 RFG (Taiwan Semiconductor Corporation) maintains identical DC current gain and Vce saturation but operates at 100 MHz transition frequency with 300 mW power dissipation. It lacks automotive qualification and operates to 150°C maximum temperature.

BC807-16 RFG and BC807-16LT3G feature reduced DC current gain (100 vs. 250) and lower power dissipation (300 mW). These parts are suitable for applications where lower current gain is acceptable.

BC807-25 RFG provides intermediate DC current gain (160) with similar electrical characteristics to the -16 variants.

BCX17T116 (Rohm Semiconductor) offers enhanced transition frequency (200 MHz) and power dissipation (425 mW) with improved Vce saturation (620 mV). This part is suitable for higher-frequency applications.

50A02CH-TL-E (onsemi) offers significantly higher transition frequency (690 MHz) and power dissipation (700 mW) but differs in package type (3-CPH) and lacks automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can BC807-40HR be used as a direct replacement for BC807-40HZ?

A: Yes. BC807-40HR is a parametric equivalent with identical electrical specifications, automotive grade, and AEC-Q101 qualification. No circuit redesign is required.

Q: What is the difference between BC807-40HZ and SBC807-40LT1G?

A: Both are automotive-qualified PNP transistors in TO-236 packages with identical Vce saturation and DC current gain. SBC807-40LT1G operates at higher transition frequency (100 MHz vs. 80 MHz) and lower power dissipation (300 mW vs. 320 mW), with maximum operating temperature of 150°C versus 175°C for BC807-40HZ.

Q: Are BC807-16 and BC807-25 variants suitable replacements?

A: BC807-16 and BC807-25 variants differ in DC current gain specification (100 and 160 respectively, versus 250 for BC807-40HZ). These parts are suitable only for applications where the lower current gain does not impact circuit performance. Verify base drive requirements before substitution.

Q: What package types are compatible with BC807-40HZ?

A: BC807-40HZ uses TO-236AB (SOT-23-3) package. Equivalent parts use TO-236-3, SC-59, or SOT-23-3 designations, which are mechanically and electrically compatible. BCX17T116 uses SST3 package, which is also mechanically compatible. 50A02CH-TL-E uses 3-CPH package, which is compatible with TO-236 footprints.

Q: Can MMBTA55-TP replace BC807-40HZ?

A: MMBTA55-TP is a similar part with higher collector-emitter breakdown voltage (60 V vs. 45 V) but reduced transition frequency (50 MHz vs. 80 MHz) and power dissipation (225 mW vs. 320 mW). It is suitable for applications where higher voltage tolerance is required and lower frequency operation is acceptable.

Q: Does BC807-40 RFG have automotive qualification?

A: No. BC807-40 RFG lacks automotive grade designation and AEC-Q101 qualification. It is suitable for non-automotive applications only.

Q: What is the significance of the -16, -25, and -40 suffixes in BC807 part numbers?

A: These suffixes indicate DC current gain (hFE) classification. BC807-16 specifies minimum hFE of 100, BC807-25 specifies minimum hFE of 160, and BC807-40 specifies minimum hFE of 250. Selection depends on required base drive current and circuit design.

Q: Is BCX17T116 suitable for high-frequency applications?

A: Yes. BCX17T116 operates at 200 MHz transition frequency, which is significantly higher than BC807-40HZ (80 MHz). It also provides enhanced power dissipation (425 mW) and improved Vce saturation (620 mV). However, it lacks automotive qualification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts carry RoHS3 compliance status. All parts also have MSL-1 (Unlimited) moisture sensitivity level.
