UP0331200L Equivalent & Substitute Parts

Part Overview

The UP0331200L is a pre-biased dual bipolar transistor (BJT) manufactured by Panasonic Electronic Components, combining one NPN and one PNP transistor in a single SSMini5-F2 surface mount package. This component is rated for 50V collector-emitter breakdown voltage, 100mA maximum collector current, and 125mW power dissipation with integrated base and emitter-base resistors of 22kOhms each.

The UP0331200L is classified as obsolete. Equivalent substitute parts are available from onsemi with active product status, offering improved availability and extended product lifecycle support while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP0331200L are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor type: 1 NPN, 1 PNP - Pre-Biased (Dual) configuration
• Maximum collector current: 100mA
• Collector-emitter breakdown voltage: 50V
• Base resistor (R1): 22kOhms
• Emitter-base resistor (R2): 22kOhms
• DC current gain (hFE): 60 minimum @ 5mA, 10V
• Vce saturation: 250mV maximum @ 300µA, 10mA
• Collector cutoff current: 500nA maximum
• Moisture sensitivity level: 1 (Unlimited)

Mechanical Compatibility Criteria:

• Surface mount packaging
• Pin configuration and footprint compatibility

The substitute parts EMC2DXV5T1G and NSVEMC2DXV5T1G from onsemi satisfy all electrical parameters. Both parts are packaged in SOT-553, which differs from the original SSMini5-F2 package. Package substitution is valid when PCB layout accommodates the alternative footprint dimensions.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The UP0331200L is classified as obsolete. Both substitute parts, EMC2DXV5T1G and NSVEMC2DXV5T1G, are active products from onsemi, ensuring continued availability and manufacturing support.

Compliance and Certifications: Both onsemi substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original UP0331200L does not specify these compliance certifications.

Power Dissipation: The substitute parts are rated for 500mW maximum power dissipation, compared to 125mW for the original part. This higher rating provides additional thermal margin in applications operating near the original specification limit.

Package Consideration: The original part uses SOT-665 (SSMini5-F2) packaging, while substitutes use SOT-553 packaging. These packages have different footprints and pin configurations. Component selection requires PCB layout compatibility with the SOT-553 package.

Electrical Equivalence: All critical electrical parameters—collector current, breakdown voltage, integrated resistor values, current gain, saturation voltage, and cutoff current—are identical across all three parts, confirming functional interchangeability at the circuit level.

Frequently Asked Questions (FAQ)

Q: Can EMC2DXV5T1G and NSVEMC2DXV5T1G be used interchangeably with UP0331200L?

A: Both onsemi parts satisfy all electrical specifications of the UP0331200L. However, they use SOT-553 packaging instead of the original SOT-665 (SSMini5-F2) package. Substitution requires PCB layout modification to accommodate the different footprint. Electrical performance is equivalent.

Q: What is the difference between EMC2DXV5T1G and NSVEMC2DXV5T1G?

A: Both parts are manufactured by onsemi and share identical electrical specifications. The primary difference is in the transistor pre-biasing configuration description: EMC2DXV5T1G is described as "Pre-Biased (Dual)" while NSVEMC2DXV5T1G is described as "Pre-Biased (Base-Collector Junction)." Both meet the electrical requirements of the original part.

Q: Why is the power rating higher on the substitute parts?

A: The onsemi substitutes are rated for 500mW maximum power dissipation compared to 125mW for the UP0331200L. This higher rating reflects the thermal capability of the SOT-553 package and does not affect circuit operation. Applications operating within the original 125mW specification remain fully compatible.

Q: Are the substitute parts available in the same package as the original?

A: No. The UP0331200L uses SOT-665 (SSMini5-F2) packaging, while EMC2DXV5T1G and NSVEMC2DXV5T1G use SOT-553 packaging. PCB redesign is required to accommodate the different footprint and pin layout.

Q: Do the substitute parts meet current environmental standards?

A: Yes. Both onsemi substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original UP0331200L does not specify these certifications.

Q: What are the integrated resistor values, and are they the same across all parts?

A: All three parts include integrated base resistors (R1) and emitter-base resistors (R2), both rated at 22kOhms. These values are identical across UP0331200L, EMC2DXV5T1G, and NSVEMC2DXV5T1G.

Q: Is the DC current gain specification identical for all parts?

A: Yes. All three parts specify a minimum DC current gain (hFE) of 60 at 5mA collector current and 10V collector-emitter voltage, ensuring equivalent amplification characteristics.
