BC847BV-7 Equivalent & Substitute Parts

Part Overview

The BC847BV-7 is a dual NPN bipolar junction transistor (BJT) array manufactured by Diodes Incorporated in SOT-563 surface mount packaging. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing production and design requirements. The BC847BV-7 operates at maximum collector current of 100mA, collector-emitter breakdown voltage of 45V, and transition frequency of 100MHz with 150mW maximum power dissipation. Substitution is required due to product discontinuation while maintaining electrical and mechanical compatibility with existing circuit designs.

Substitute Part Grouping Explanation

Substitution of the BC847BV-7 is determined by the following critical parameters: transistor type (dual NPN configuration), maximum collector current (100mA minimum), collector-emitter breakdown voltage (45V minimum), saturation voltage characteristics, DC current gain specifications, and surface mount packaging compatibility (SOT-563 or SOT-666). Parts are grouped into three categories based on electrical equivalence and product status:

Category 1: Direct Electrical Equivalents (Active Status) Parts maintaining identical electrical specifications with active product status and current manufacturing availability.

Category 2: Enhanced Performance Equivalents (Active Status) Parts exceeding minimum electrical specifications while maintaining backward compatibility and active product status.

Category 3: Legacy Equivalents (Not For New Designs) Parts meeting electrical specifications but designated as not for new designs, suitable for replacement in existing production only.

Engineering Selection Recommendations

For Direct Replacement in Active Production:

BC847BV-TP (Micro Commercial Co) is the primary recommended substitute. This part maintains identical electrical specifications to the BC847BV-7, including 100mA maximum collector current, 45V breakdown voltage, 300mV saturation voltage, and 100MHz transition frequency. The part is in active product status with high inventory availability (9704 units). Packaging is SOT-563 with Cut Tape (CT) configuration, matching the original component footprint and assembly requirements.

For Enhanced Performance Applications:

BC847CDXV6T1G (onsemi) provides enhanced electrical performance while maintaining backward compatibility. This part exceeds the original specifications with 500mW maximum power dissipation (versus 150mW), higher DC current gain (420 versus 200), and identical voltage and current ratings. Active product status and SOT-563 packaging ensure direct substitution capability. This option is suitable for designs requiring improved thermal performance or higher gain margins.

For Increased Current Capability:

NST3904DXV6T1G (onsemi) and NSVT3904DXV6T1G (onsemi) support doubled maximum collector current (200mA versus 100mA) while maintaining 40V minimum breakdown voltage. These parts feature 300MHz transition frequency and 500mW power dissipation. Both are in active product status. These substitutes are applicable when circuit designs require higher current handling capacity within the same package footprint.

For Legacy System Maintenance:

BC847BV,115 and BC847BV,315 (Nexperia USA Inc.) are designated as not for new designs but remain available for replacement in existing production. These parts maintain identical electrical specifications with SOT-666 packaging and 300mW power dissipation. Use is restricted to sustaining production of existing designs only.

Frequently Asked Questions (FAQ)

Q: Can BC847BV-TP directly replace BC847BV-7 without circuit modification?

A: Yes. BC847BV-TP maintains identical electrical specifications including collector current (100mA), breakdown voltage (45V), saturation voltage (300mV), DC current gain (200), and transition frequency (100MHz). Both components use SOT-563 packaging with identical pinout and thermal characteristics. No circuit modification is required.

Q: What is the difference between BC847BV-7 and BC847CDXV6T1G?

A: BC847CDXV6T1G exceeds the original specifications in three parameters: maximum power dissipation (500mW versus 150mW), DC current gain (420 versus 200), and saturation voltage (600mV versus 300mV). All voltage and current ratings remain identical. BC847CDXV6T1G is suitable for applications requiring improved thermal performance or higher gain margins.

Q: Why are NST3904DXV6T1G and NSVT3904DXV6T1G listed as substitutes if they have different current ratings?

A: These parts support doubled maximum collector current (200mA versus 100mA) and higher transition frequency (300MHz versus 100MHz), making them suitable for designs requiring enhanced performance. However, they operate at 40V breakdown voltage (versus 45V) and feature different saturation voltage characteristics. These parts are applicable only when circuit designs can accommodate the modified electrical parameters.

Q: What packaging options are available for BC847BV-7 substitutes?

A: Substitutes are available in two package types: SOT-563 (smaller footprint, 6-pin) and SOT-666 (larger footprint, 6-pin). BC847BV-TP, BC847CDXV6T1G, NST3904DXV6T1G, NSVT3904DXV6T1G, and MMDT3904V-TP use SOT-563 packaging, matching the original BC847BV-7 footprint. BC847BV,115 and BC847BV,315 use SOT-666 packaging and require PCB layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (unlimited moisture sensitivity rating), matching the original BC847BV-7 environmental specifications.

Q: What is the difference between BC847BV,115 and BC847BV,315?

A: Both parts are manufactured by Nexperia USA Inc. and maintain identical electrical specifications. The primary difference is inventory availability (BC847BV,315 has 73603 units versus BC847BV,115 with 6356 units). Both are designated as not for new designs and use SOT-666 packaging.

Q: Can BCM847BV,115 be used as a substitute for BC847BV-7?

A: BCM847BV,115 is a matched pair variant with enhanced transition frequency (250MHz versus 100MHz) and modified saturation voltage (400mV versus 300mV). While electrical parameters remain within acceptable ranges, the matched pair specification and higher transition frequency indicate this part is optimized for precision applications. Use is restricted to designs specifically requiring matched pair characteristics.

Q: What is the recommended substitute for new design work?

A: BC847BV-TP (Micro Commercial Co) is recommended for new designs. This part maintains identical specifications to the original BC847BV-7, is in active product status, and has high inventory availability. Alternatively, BC847CDXV6T1G (onsemi) is suitable for new designs requiring enhanced thermal performance or higher gain margins.
