Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

BC807-40W RFG is the direct functional equivalent to BC807-40W-TP. Both parts maintain identical electrical specifications including 250 mA minimum DC current gain, 80 MHz transition frequency, and 200 mW power dissipation. The primary difference is packaging format (Tape & Reel versus Bulk) and manufacturer (Taiwan Semiconductor Corporation versus Micro Commercial Co). This part is ROHS3 compliant and carries MSL 1 rating.

Compatible Alternatives with Enhanced Performance:

BC807-25W RFG and BC807-25-7-F provide equivalent primary electrical performance with enhanced DC current gain (160 mA minimum) while maintaining all critical voltage and current specifications. BC807-25-7-F offers increased power dissipation (310 mW) and higher transition frequency (100 MHz), providing additional design margin.

BC807-16W RFG and BC807-16-7-F are suitable substitutes with reduced DC current gain (100 mA minimum) but maintain all voltage, current, and temperature specifications. These parts are appropriate for applications where lower gain is acceptable.

Enhanced Performance Alternative:

SBC807-25WT1G, manufactured by onsemi, provides the highest power dissipation capability (460 mW) and transition frequency (100 MHz) among all listed alternatives. This part carries AEC-Q101 automotive qualification and is suitable for applications requiring automotive-grade reliability. DC current gain is specified at 160 mA minimum.

All substitute parts maintain the required 45 V collector-emitter breakdown voltage, 500 mA maximum collector current, and -55°C to 150°C operating temperature range. All listed alternatives are active products with current manufacturing status.

Frequently Asked Questions (FAQ)

Q: Can BC807-40W RFG be used as a direct replacement for BC807-40W-TP?

A: Yes. BC807-40W RFG is electrically and mechanically equivalent to BC807-40W-TP. Both parts share identical specifications for collector current (500 mA), collector-emitter breakdown voltage (45 V), saturation voltage (700 mV), power dissipation (200 mW), and transition frequency (80 MHz). The primary difference is the packaging format (Tape & Reel versus Bulk) and manufacturer source.

Q: What is the difference between SOT-323 and SOT-23-3 packages?

A: SOT-323 (also designated SC-70) and SOT-23-3 (also designated SC-59) are both three-terminal surface mount packages with different physical dimensions and land patterns. SOT-323 is smaller than SOT-23-3. Parts specified for SOT-23-3 (BC807-16-7-F and BC807-25-7-F) have different PCB footprints and are not mechanically interchangeable with SOT-323 parts without board redesign.

Q: Can I use BC807-16-7-F or BC807-16W RFG if the original design specifies BC807-40W-TP?

A: BC807-16-7-F and BC807-16W RFG are electrically compatible substitutes with one specification difference: DC current gain is specified at 100 mA minimum, compared to 250 mA minimum for BC807-40W-TP. These parts are suitable for replacement only if the circuit design does not depend on the higher gain specification. All other electrical parameters (voltage, current, temperature, saturation) are equivalent.

Q: What is the advantage of using SBC807-25WT1G over BC807-40W-TP?

A: SBC807-25WT1G provides three performance enhancements: higher power dissipation (460 mW versus 200 mW), higher transition frequency (100 MHz versus 80 MHz), and AEC-Q101 automotive qualification. These enhancements provide additional design margin for thermal and frequency performance. The part is suitable for applications requiring automotive-grade reliability.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are specified as ROHS3 compliant. The main part BC807-40W-TP does not specify RoHS status in the provided data. All substitute parts carry MSL 1 (Unlimited) moisture sensitivity level rating.

Q: What is the difference between BC807-25W RFG and BC807-25-7-F?

A: Both parts share the same DC current gain specification (160 mA minimum) and base part number (BC807-25). The primary differences are: manufacturer (Taiwan Semiconductor Corporation versus Diodes Incorporated), package format (SOT-323 versus SOT-23-3), packaging type (Tape & Reel versus Cut Tape & Digi-Reel), and power dissipation (200 mW versus 310 mW). The SOT-23-3 package requires different PCB footprint design.

Q: Can I substitute parts with different DC current gain specifications?

A: DC current gain substitution depends on circuit design requirements. Parts with higher gain (BC807-40W RFG, BC807-25W RFG, BC807-25-7-F, SBC807-25WT1G at 160-250 mA) are suitable replacements for designs specifying lower gain. Parts with lower gain (BC807-16W RFG, BC807-16-7-F at 100 mA) are suitable only if the circuit does not require the higher gain specification.

Q: What inventory levels are available for each substitute part?

A: BC807-40W RFG: 6,778 pcs; BC807-16W RFG: 6,744 pcs; BC807-25W RFG: 6,729 pcs; BC807-16-7-F: 15,635 pcs; BC807-25-7-F: 26,100 pcs; SBC807-25WT1G: 20,400 pcs. The main part BC807-40W-TP has 1,004 pcs in stock.
