Substitute Part Grouping Explanation

Substitution of the BCW68HTC is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor type must be PNP
Package must be SOT-23-3 (TO-236-3, SC-59)
Collector-emitter breakdown voltage must be 45 V or greater
Maximum collector current must be 800 mA or greater
Power dissipation must be 330 mW or greater
Operating temperature range must encompass −55°C to 150°C
DC current gain (hFE) minimum must be 250 or greater at specified test conditions
Transition frequency must be 100 MHz or greater

Secondary Substitution Criteria (Reduced Current Rating): Parts with collector current ratings of 500 mA are acceptable substitutes when circuit design permits operation within this reduced current envelope. These parts maintain all other critical electrical parameters and package compatibility.

Tertiary Substitution Criteria (Reduced Current and Frequency): Parts with collector current ratings of 100 mA and transition frequency of 70–80 MHz are acceptable only for applications where maximum collector current does not exceed 100 mA and frequency response requirements are met at the lower transition frequency specification.

All substitute parts must maintain ROHS3 compliance and MSL-1 moisture sensitivity rating.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Specifications):

BCW68HTA is the primary direct replacement for BCW68HTC. Both devices are manufactured by Diodes Incorporated and share identical electrical specifications: 800 mA maximum collector current, 45 V breakdown voltage, 330 mW power dissipation, 100 MHz transition frequency, and −55°C to 150°C operating temperature range. BCW68HTA maintains active product status with 2000 units in stock, ensuring production continuity and long-term availability.

Primary Substitutes (500 mA Collector Current Rating):

BC807-40-7-F, BC807-16LT1G, BC807-16LT3G, BC807-16 RFG, BC807,215, and BC807-16,215 are acceptable substitutes for applications where maximum collector current does not exceed 500 mA. All maintain 45 V breakdown voltage, 100 MHz (or 80 MHz for Nexperia variants) transition frequency, and −55°C to 150°C operating temperature range. These parts are manufactured by Diodes Incorporated, onsemi, Taiwan Semiconductor Corporation, and Nexperia USA Inc., all with active product status and substantial inventory availability.

Secondary Substitutes (100 mA Collector Current Rating):

2PB709ARL,215, 2PB709ART,235, and 2PB709ASL,215 are acceptable substitutes only for applications where maximum collector current does not exceed 100 mA. These Nexperia devices maintain 45 V breakdown voltage and −55°C to 150°C operating temperature range. All three parts carry AEC-Q101 automotive qualification and active product status. Transition frequency ranges from 70 MHz to 80 MHz, which is lower than the BCW68HTC specification of 100 MHz.

Compliance and Certification:

All substitute parts maintain ROHS3 compliance and MSL-1 moisture sensitivity rating, matching the BCW68HTC specifications. Nexperia variants include AEC-Q101 automotive qualification, providing additional qualification for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can BC807-40-7-F be used as a direct replacement for BCW68HTC?

A: BC807-40-7-F is electrically compatible with BCW68HTC for applications where maximum collector current does not exceed 500 mA. The part maintains identical 45 V breakdown voltage, 100 MHz transition frequency, and −55°C to 150°C operating temperature range. However, the maximum collector current rating is reduced from 800 mA to 500 mA. Circuit design must confirm that collector current does not exceed 500 mA during normal operation.

Q: What is the difference between BC807-16LT1G and BC807-16LT3G?

A: BC807-16LT1G and BC807-16LT3G are identical in electrical specifications and differ only in packaging format. BC807-16LT1G is supplied in Cut Tape (CT) & Digi-Reel format, while BC807-16LT3G is supplied in Tape & Reel (TR) format. Both are manufactured by onsemi and maintain 500 mA collector current, 45 V breakdown voltage, 100 MHz transition frequency, and −55°C to 150°C operating temperature range.

Q: Are the 2PB709 series parts suitable replacements for high-current applications?

A: No. The 2PB709 series (2PB709ARL,215, 2PB709ART,235, 2PB709ASL,215) are rated for maximum collector current of 100 mA, which is significantly lower than the BCW68HTC rating of 800 mA. These parts are suitable only for low-current applications where collector current does not exceed 100 mA. Additionally, transition frequency is reduced to 70–80 MHz compared to the BCW68HTC specification of 100 MHz.

Q: Does package compatibility affect substitution?

A: All substitute parts listed maintain the SOT-23-3 package specification, ensuring mechanical and electrical compatibility with PCB layouts designed for BCW68HTC. No package conversion or board redesign is required.

Q: What is the significance of the Nexperia AEC-Q101 qualification?

A: AEC-Q101 is an automotive qualification standard. Nexperia variants (BC807,215, BC807-16,215, 2PB709ARL,215, 2PB709ART,235, 2PB709ASL,215) carry this qualification, making them suitable for automotive applications requiring this certification. Non-automotive applications do not require this qualification.

Q: Can I use BC807-16 RFG from Taiwan Semiconductor Corporation instead of a Diodes Incorporated part?

A: Yes. BC807-16 RFG maintains identical electrical specifications to other BC807-16 variants: 500 mA collector current, 45 V breakdown voltage, 100 MHz transition frequency, and −55°C to 150°C operating temperature range. Substitution is valid for applications where 500 mA collector current is acceptable. Verify that your supply chain and quality requirements accommodate Taiwan Semiconductor Corporation as a manufacturer.

Q: What is the primary reason BCW68HTC is obsolete?

A: The BCW68HTC is classified as obsolete by Diodes Incorporated. BCW68HTA is the active replacement part with identical electrical specifications. For new designs and production continuity, BCW68HTA should be specified. For existing designs using BCW68HTC, transition to BCW68HTA is recommended to ensure long-term component availability.

Q: How do I determine which substitute part is appropriate for my application?

A: Identify the maximum collector current required by your circuit. If maximum collector current is 800 mA or greater, specify BCW68HTA. If maximum collector current is between 500 mA and 800 mA, any BC807 variant is acceptable. If maximum collector current is 100 mA or less, 2PB709 variants are acceptable. Verify that transition frequency requirements are met: 100 MHz for BCW68HTC, 80–100 MHz for BC807 variants, and 70–80 MHz for 2PB709 variants.
