Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

BC847BV-TP and BC847BVC-7 are the preferred substitutes for direct replacement of BC847BV,115. Both maintain identical electrical specifications (45V, 100mA, 100MHz, 200 hFE minimum) and are in active product status. BC847BVC-7 offers higher inventory availability (70,960 units) compared to BC847BV-TP (9,704 units). Both are RoHS3 compliant with unlimited moisture sensitivity level. The primary difference is packaging: BC847BV-TP is supplied in Cut Tape format while BC847BVC-7 is supplied in Tape & Reel format.

Enhanced Performance Alternative:

BC847CDXV6T1G (onsemi) provides superior electrical performance with 500mW power dissipation (versus 300mW in the original) and higher DC current gain (420 hFE minimum versus 200). This part maintains 45V breakdown voltage and 100mA collector current ratings. The higher Vce saturation (600mV) may require circuit evaluation in saturation-mode applications. This part is in active status with 6,678 units in stock.

Secondary Alternatives (Modified Electrical Characteristics):

MMDT3904V-TP, MMDT3904VC-7, NST3904DXV6T1G, and NSVT3904DXV6T1G are functionally compatible alternatives with reduced collector-emitter breakdown voltage (40V versus 45V) and increased collector current capability (200mA versus 100mA). These parts are suitable for applications where the 40V rating is acceptable and higher current handling is beneficial. All are in active product status and RoHS3 compliant.

MMDT2222V-7 offers significantly higher collector current (600mA) and transition frequency (300MHz) with reduced breakdown voltage (40V). This part is suitable for high-speed, high-current applications where the voltage derating is acceptable.

EMX1DXV6T5G is designated as obsolete and should not be selected for new designs despite higher transition frequency (180MHz) and power rating (500mW).

All substitute parts maintain surface mount technology, SOT-563/SOT-666 package compatibility, and RoHS3 compliance. Selection should be based on specific application requirements for voltage rating, current capacity, and frequency response.

Frequently Asked Questions (FAQ)

Q: Can BC847BV-TP directly replace BC847BV,115 in existing designs?

A: Yes. BC847BV-TP maintains identical electrical specifications: 45V breakdown voltage, 100mA collector current, 100MHz transition frequency, and 200 hFE minimum. Both are dual NPN arrays in surface mount packages. The primary difference is packaging format (Cut Tape versus Tape & Reel). Electrical performance is equivalent.

Q: What is the difference between BC847BVC-7 and BC847BV-TP?

A: Both parts have identical electrical specifications and are functionally equivalent. The differences are: manufacturer (Diodes Incorporated versus Micro Commercial Co), packaging format (Tape & Reel versus Cut Tape), and inventory availability. BC847BVC-7 has significantly higher stock (70,960 units).

Q: Why does BC847CDXV6T1G have different Vce saturation and hFE specifications?

A: BC847CDXV6T1G is manufactured by onsemi and represents a variant within the BC847 family with enhanced performance characteristics. The higher DC current gain (420 versus 200) and higher power rating (500mW versus 300mW) provide improved performance margin. The increased Vce saturation (600mV versus 300mV) reflects different transistor design. This part is suitable for applications where enhanced performance is beneficial.

Q: Can MMDT3904V-TP be used as a substitute despite the 40V rating?

A: MMDT3904V-TP can be used in applications where the 40V collector-emitter breakdown voltage is acceptable. This represents a 5V reduction from the original 45V specification. The part offers higher collector current (200mA versus 100mA) and higher transition frequency (300MHz versus 100MHz). Circuit design must confirm that maximum operating voltages remain below 40V.

Q: What is the significance of "Not For New Designs" status on BC847BV,115?

A: This status indicates the manufacturer no longer recommends this part for new circuit development. Existing designs may continue using current inventory, but new designs should select from active-status alternatives such as BC847BV-TP, BC847BVC-7, or BC847CDXV6T1G to ensure long-term supply availability and manufacturer support.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1), matching the compliance profile of BC847BV,115.

Q: What is the package compatibility between SOT-563 and SOT-666?

A: Both SOT-563 and SOT-666 are surface mount packages for dual transistor arrays. SOT-666 is the original package for BC847BV,115. Most substitute parts are available in SOT-563 packaging, which is mechanically compatible with SOT-666 footprints in most applications. PCB layout and thermal considerations should be evaluated for specific designs.

Q: Should NST3904DXV6T5G be selected for new designs?

A: No. NST3904DXV6T5G is designated as obsolete. NST3904DXV6T1G is the active-status equivalent from onsemi with identical electrical specifications. NST3904DXV6T1G should be selected for new designs requiring this performance level.

Q: What is the primary reason to select BC847BVC-7 over BC847BV-TP?

A: BC847BVC-7 offers significantly higher inventory availability (70,960 units versus 9,704 units) and is supplied in standard Tape & Reel packaging format. Both parts are electrically identical. BC847BVC-7 is the preferred choice for volume production and long-term supply security.
