Substitute Part Grouping Explanation

Substitution of the BC847C/SNVL is determined by strict equivalence of the following electrical and mechanical parameters:

Primary Substitution Criteria:

Transistor type: NPN
Maximum collector current: 100 mA
Collector-emitter breakdown voltage: 45 V
Maximum power dissipation: 250 mW
DC current gain (hFE): minimum 420 @ 2 mA, 5 V
Transition frequency: 100 MHz
Operating temperature: 150°C (TJ)
Package: TO-236-3 / SOT-23-3 surface mount
Compliance: AEC-Q101 automotive qualification, ROHS3

Substitution Categories:

Direct Equivalents (Identical Electrical Parameters): Parts with matching Vce saturation specifications (400 mV @ 5 mA, 100 mA) and all other electrical parameters identical to the main part. These parts differ only in packaging format (Tape & Reel or Cut Tape) or internal manufacturing codes.

Parametric Equivalents (Functionally Compatible): Parts with identical electrical performance across all critical parameters but available in different packaging configurations or manufacturing variants. All maintain AEC-Q101 qualification and automotive-grade specifications.

Similar Parts (Comparable Performance): Parts from alternative manufacturers with the same package footprint and compatible electrical characteristics, though with variations in specific parameters such as transition frequency or DC current gain that do not preclude functional substitution in most applications.

Parametric Alternatives (Higher Vce Saturation):

The BC850C series parts (BC850C,215 and BC850C,235) are functionally compatible with the BC847C/SNVL across all parameters except Vce saturation, which is specified at 600 mV (versus 400 mV for BC847C). These parts are suitable for applications where saturation voltage tolerance is not critical. Both variants maintain AEC-Q101 automotive qualification and active production status.

Alternative Manufacturer Option (Comparable Performance):

BC847A-7-F (Diodes Incorporated) offers compatible package and basic electrical specifications but differs in DC current gain (110 versus 420 minimum) and transition frequency (300 MHz versus 100 MHz). This part is suitable only for applications where higher gain and frequency performance are acceptable or beneficial. AEC-Q101 qualification status is not specified.

Recommendation for Obsolete Part Replacement:

For direct substitution of the obsolete BC847C/SNVL, select BC847C,235 or BC847C,215 from Nexperia USA Inc. Both parts are in active production with substantial inventory availability, maintain identical electrical specifications, and carry AEC-Q101 automotive qualification. Selection between these two should be based on packaging requirements: Tape & Reel (BC847C,235) for automated assembly or Cut Tape & Digi-Reel (BC847C,215) for manual or mixed-volume applications.

Frequently Asked Questions (FAQ)

Q: Can BC847C,235 be used as a direct replacement for BC847C/SNVL?

A: Yes. BC847C,235 is a direct equivalent with identical electrical specifications, including collector current (100 mA), breakdown voltage (45 V), Vce saturation (400 mV @ 5 mA, 100 mA), DC current gain (420 minimum @ 2 mA, 5 V), power dissipation (250 mW), and transition frequency (100 MHz). Both parts are housed in TO-236AB packages and carry AEC-Q101 automotive qualification. The primary difference is packaging format: BC847C,235 is supplied in Tape & Reel format.

Q: What is the difference between BC847C,235 and BC847C,215?

A: Both parts are electrically identical with matching specifications. The difference is in packaging format: BC847C,235 is supplied in Tape & Reel (TR) format, while BC847C,215 is supplied in Cut Tape (CT) & Digi-Reel format. Selection depends on assembly process requirements. Tape & Reel is standard for automated pick-and-place equipment, while Cut Tape & Digi-Reel is suitable for manual assembly or lower-volume applications.

Q: Can BC850C parts be substituted for BC847C/SNVL?

A: BC850C parts are functionally compatible with BC847C/SNVL across all electrical parameters except Vce saturation. BC850C specifies 600 mV saturation voltage compared to 400 mV for BC847C. This difference is acceptable in applications where saturation voltage tolerance is not critical. Both BC850C,215 and BC850C,235 maintain AEC-Q101 automotive qualification and active production status.

Q: What does AEC-Q101 qualification mean?

A: AEC-Q101 is an automotive electronics qualification standard that certifies components for use in automotive applications. It establishes reliability and performance requirements for semiconductor devices operating in automotive environments. All recommended direct replacements for BC847C/SNVL carry this qualification, ensuring compatibility with automotive-grade design requirements.

Q: Is the BC847A-7-F from Diodes Incorporated a suitable replacement?

A: BC847A-7-F is compatible in terms of package footprint (SOT-23-3) and basic electrical ratings (100 mA, 45 V). However, it differs in DC current gain (110 minimum versus 420 for BC847C) and transition frequency (300 MHz versus 100 MHz). This part is suitable only for applications where these parameter differences do not affect circuit performance. AEC-Q101 qualification status is not specified for this part.

Q: What is the difference between BC847C-QR and BC847C-QVL?

A: Both parts are electrically identical to BC847C/SNVL with matching specifications. The designations indicate different manufacturing or qualification variants within the BC847x-Q series. Both are supplied in Tape & Reel format and maintain AEC-Q101 automotive qualification. Selection between these variants should be based on availability and specific supply chain requirements.

Q: Are BC847C/DG/B4R and BC847C/DG/B4VL suitable replacements?

A: Yes. Both parts maintain identical electrical specifications to BC847C/SNVL across all critical parameters. The designations indicate internal manufacturing variants. AEC-Q101 qualification status is not explicitly specified in available data for these variants. Confirm automotive qualification requirements with the supplier before selection for automotive applications.

Q: What is the significance of the MSL (Moisture Sensitivity Level) rating?

A: All recommended parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Components can be stored and handled without special moisture control measures, simplifying supply chain management and reducing handling costs compared to higher MSL-rated components.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, for direct electrical equivalents (BC847C,235, BC847C,215, BC847C-QR, BC847C-QVL). All maintain identical electrical specifications and package footprints. Verify packaging format compatibility with assembly equipment. For BC850C variants, confirm that the higher Vce saturation (600 mV) does not affect circuit performance. For BC847A-7-F, verify that differences in gain and frequency are acceptable for the specific application.

Q: What inventory levels are available for these parts?

A: BC847C,235 has 109,071 units in stock. BC847C,215 has 31,630 units in stock. BC847C-QR has 25,060 units in stock. BC850C,215 has 85,230 units in stock. BC850C,235 has 44,122 units in stock.
