BC846BS-TP Equivalent & Substitute Parts

Part Overview

The BC846BS-TP is an active Bipolar (BJT) Transistor Array containing 2 NPN transistors in a Surface Mount SOT-363 package. This component is manufactured by Micro Commercial Co and is designed for interface applications requiring dual NPN transistor functionality. The part is currently in active product status with 721 pieces in stock inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct replacement in circuit designs without functional degradation. Substitution becomes necessary due to supply chain availability, packaging format preferences, or specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BC846BS-TP is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Transistor Type: 2 NPN configuration
• Current - Collector (Ic) (Max): 100mA minimum
• Voltage - Collector Emitter Breakdown (Max): 65V minimum
• Frequency - Transition: 100MHz minimum
• Operating Temperature Range: Must encompass -55°C to 150°C

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: Compatible with 6-TSSOP, SC-88, or SOT-363 footprints

Secondary Parameters:

• Current - Collector Cutoff (Max): 15nA (ICBO)
• DC Current Gain (hFE) (Min): 200 @ 2mA, 5V or higher

Parts meeting all electrical equivalence criteria and mechanical compatibility are classified as direct substitutes. Variations in Vce Saturation, Power dissipation, or Frequency - Transition above the minimum thresholds do not preclude substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—BC846BDW1T1G, BC846SF, and BCM846BSX—meet the core electrical and mechanical substitution criteria for the BC846BS-TP.

BC846BDW1T1G (onsemi): This part maintains electrical equivalence across all critical parameters including 100mA collector current, 65V breakdown voltage, and 100MHz transition frequency. The higher maximum power dissipation (380mW versus 200mW) provides additional thermal margin. ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) are provided. Packaging is available in Cut Tape and Digi-Reel formats.

BC846SF (Nexperia USA Inc.): This part provides electrical equivalence with identical Vce Saturation and power specifications to the main part. The DC Current Gain minimum is specified at 110 @ 2mA, 5V, which is lower than the main part's 200 specification. ROHS3 compliance is provided. Packaging is available in Tape & Reel format. Operating temperature maximum is specified at 150°C without lower bound documentation.

BCM846BSX (Nexperia USA Inc.): This automotive-grade part (AEC-Q101 qualified) exceeds electrical specifications with 250MHz transition frequency and improved Vce Saturation performance (200mV @ 500µA, 10mA). ROHS3 compliance and unlimited MSL 1 rating are provided. Packaging is available in Cut Tape and Digi-Reel formats. This part is suitable for applications requiring automotive qualification.

All substitute parts are active products with established inventory availability. Selection should be based on packaging format requirements, compliance certifications needed for the end application, and thermal performance margins.

Frequently Asked Questions (FAQ)

Q: Can BC846BDW1T1G replace BC846BS-TP in all applications?

A: BC846BDW1T1G meets all electrical and mechanical substitution criteria. The higher power dissipation rating (380mW versus 200mW) is compatible with BC846BS-TP applications. Packaging compatibility exists across 6-TSSOP, SC-88, and SOT-363 footprints. Substitution is valid from an electrical standpoint.

Q: What is the difference between BC846SF and BC846BS-TP?

A: BC846SF provides equivalent electrical performance in core parameters (100mA Ic, 65V breakdown, 100MHz transition). The DC Current Gain minimum specification differs (110 versus 200 @ 2mA, 5V). Both parts use compatible Surface Mount packages. BC846SF is available in Tape & Reel packaging format.

Q: Is BCM846BSX suitable for automotive applications?

A: BCM846BSX carries AEC-Q101 automotive qualification and is designated as automotive-grade. This part exceeds the electrical specifications of BC846BS-TP with 250MHz transition frequency. It is suitable for automotive applications requiring this qualification level.

Q: Are all substitute parts RoHS compliant?

A: BC846BDW1T1G, BC846SF, and BCM846BSX are all ROHS3 compliant. The main part BC846BS-TP does not specify RoHS status in the provided data. All parts maintain REACH Unaffected status.

Q: What packaging formats are available for substitutes?

A: BC846BDW1T1G and BCM846BSX are available in Cut Tape (CT) and Digi-Reel formats. BC846SF is available in Tape & Reel (TR) format. All parts are compatible with 6-TSSOP, SC-88, and SOT-363 footprints.

Q: Can BC846SF be used if lower DC Current Gain is acceptable?

A: BC846SF specifies DC Current Gain minimum of 110 @ 2mA, 5V, compared to 200 for BC846BS-TP. Substitution is valid if circuit design accommodates this lower gain specification. Applications requiring minimum gain of 200 should use BC846BDW1T1G or BCM846BSX.

Q: What is the operating temperature range for BC846SF?

A: BC846SF specifies maximum operating temperature of 150°C (TJ). The lower temperature bound is not documented in the provided data. BC846BS-TP specifies -55°C to 150°C range. Verify lower temperature requirements for your application.

Q: Are all substitute parts in active product status?

A: All three substitute parts—BC846BDW1T1G, BC846SF, and BCM846BSX—are in active product status with established inventory availability (69530, 10995, and 25758 pieces respectively).
