Electrical Parameters:

• Transistor Type: NPN
• Maximum Collector Current (Ic): 1 A
• Collector-Emitter Breakdown Voltage: 80 V
• Vce Saturation: 500mV @ 50mA, 500mA
• Collector Cutoff Current: 100nA (ICBO)
• DC Current Gain (hFE): 63 minimum @ 150mA, 2V
• Maximum Power Dissipation: 420 mW
• Transition Frequency: 180 MHz

Mechanical Parameters:

• Package Type: 3-UDFN Exposed Pad
• Mounting Type: Surface Mount
• Supplier Device Package: DFN2020D-3

Compliance Parameters:

• Grade: Automotive
• Qualification: AEC-Q100
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts are classified into two categories: Parametric Equivalents (identical electrical and mechanical specifications) and Similar Parts (matching core electrical parameters with minor variations in secondary specifications).

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalents (BC56-16PASX and BC56PASX):

The BC56-16PASX and BC56PASX are direct parametric equivalents to the BC56-10PASX. Both parts are manufactured by Nexperia USA Inc. and maintain identical electrical specifications, including collector current, breakdown voltage, saturation characteristics, current gain, power dissipation, and transition frequency. All three parts share the same 3-UDFN Exposed Pad package configuration and are qualified to AEC-Q100 automotive standards. These parts are interchangeable for applications requiring the specified electrical performance and automotive-grade reliability. Selection among these three Nexperia parts may be based on inventory availability and packaging format (Tape & Reel).

Similar Part (BC56-16PA-7):

The BC56-16PA-7, manufactured by Diodes Incorporated, is a similar NPN transistor that matches the core electrical parameters of the BC56-10PASX. This part maintains the same maximum collector current (1 A), collector-emitter breakdown voltage (80 V), saturation characteristics, and cutoff current. However, the BC56-16PA-7 exhibits the following differences:

• DC Current Gain (hFE): 100 minimum (versus 63 for BC56-10PASX), indicating higher current amplification capability
• Maximum Power Dissipation: 520 mW (versus 420 mW), providing greater thermal headroom
• Transition Frequency: 125 MHz (versus 180 MHz), representing lower high-frequency performance
• Operating Temperature Range: -65°C to 150°C (versus 150°C maximum for BC56-10PASX), offering extended low-temperature operation
• Qualification: AEC-Q101 (versus AEC-Q100), indicating a different automotive qualification standard
• Supplier Device Package: U-DFN2020-3 (versus DFN2020D-3), representing a variant package designation

The BC56-16PA-7 is suitable for applications where higher current gain, increased power dissipation capability, or extended temperature range are beneficial. The lower transition frequency may limit use in high-speed switching applications. All parts maintain ROHS3 compliance and automotive-grade status.

Frequently Asked Questions (FAQ)

Q: Can BC56-16PASX and BC56PASX be used interchangeably with BC56-10PASX?

A: Yes. BC56-16PASX and BC56PASX are parametric equivalents with identical electrical and mechanical specifications. All three parts share the same NPN transistor type, 1 A maximum collector current, 80 V breakdown voltage, 420 mW power rating, 180 MHz transition frequency, and 3-UDFN Exposed Pad package. All are AEC-Q100 qualified and ROHS3 compliant. Selection is based on inventory availability and packaging format.

Q: Is BC56-16PA-7 a direct substitute for BC56-10PASX?

A: BC56-16PA-7 is a similar part with matching core electrical parameters but contains specification differences. The BC56-16PA-7 offers higher DC current gain (100 versus 63), greater power dissipation (520 mW versus 420 mW), and extended temperature range (-65°C to 150°C versus 150°C maximum). However, it operates at a lower transition frequency (125 MHz versus 180 MHz) and carries AEC-Q101 qualification instead of AEC-Q100. Use BC56-16PA-7 when these differences align with application requirements.

Q: What package types are used for these substitute parts?

A: All substitute parts use the 3-UDFN Exposed Pad surface mount package. BC56-10PASX, BC56-16PASX, and BC56PASX use the DFN2020D-3 supplier device package designation. BC56-16PA-7 uses the U-DFN2020-3 supplier device package designation. Both designations refer to the same physical 3-UDFN Exposed Pad package footprint suitable for surface mount assembly.

Q: Are all substitute parts automotive-grade?

A: Yes. All substitute parts carry automotive-grade classification. BC56-10PASX, BC56-16PASX, and BC56PASX are qualified to AEC-Q100. BC56-16PA-7 is qualified to AEC-Q101. Both AEC-Q100 and AEC-Q101 are automotive qualification standards. All parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between AEC-Q100 and AEC-Q101 qualifications?

A: AEC-Q100 and AEC-Q101 are distinct automotive qualification standards. The BC56-10PASX, BC56-16PASX, and BC56PASX carry AEC-Q100 qualification. The BC56-16PA-7 carries AEC-Q101 qualification. Both standards establish reliability and quality requirements for automotive semiconductor components. Selection between these qualifications depends on specific automotive application requirements and OEM specifications.

Q: Can BC56-10PASX be used in high-frequency switching applications?

A: BC56-10PASX operates at a transition frequency of 180 MHz, supporting high-frequency switching applications within this bandwidth. BC56-16PASX and BC56PASX maintain the same 180 MHz transition frequency. BC56-16PA-7 operates at 125 MHz, which is lower. For applications requiring operation above 125 MHz, use BC56-10PASX, BC56-16PASX, or BC56PASX.

Q: What is the maximum power dissipation for each part?

A: BC56-10PASX, BC56-16PASX, and BC56PASX are rated for 420 mW maximum power dissipation. BC56-16PA-7 is rated for 520 mW maximum power dissipation. Applications requiring power dissipation above 420 mW may benefit from BC56-16PA-7, which provides additional thermal margin.

Q: Are these parts suitable for surface mount assembly?

A: Yes. All substitute parts are classified as Surface Mount devices with 3-UDFN Exposed Pad packages. They are designed for automated surface mount assembly processes and are supplied in Tape & Reel or Cut Tape & Digi-Reel® packaging formats suitable for pick-and-place equipment.
