2SCR583D3FRATL Equivalent & Substitute Parts

Part Overview

The 2SCR583D3FRATL is an NPN bipolar junction transistor manufactured by Rohm Semiconductor, designed for surface mount applications in the TO-252 (DPAK) package. This component operates at 50V collector-emitter breakdown voltage with a maximum collector current of 7A and 10W power dissipation capability. The device is qualified to AEC-Q101 automotive standards and maintains active product status. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity while maintaining identical functional performance.

Substitute Part Grouping Explanation

Substitute parts for the 2SCR583D3FRATL are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires matching the following parameters:

• Transistor polarity: NPN
• Maximum collector-emitter breakdown voltage: 50V
• Maximum collector current: 7A
• Maximum power dissipation: 10W
• Transition frequency: 280MHz
• DC current gain (hFE): 180 minimum at specified conditions
• Saturation voltage: 350mV maximum at specified bias conditions
• Collector cutoff current: 1µA maximum
• Operating temperature range: 150°C maximum junction temperature
• Package type: TO-252-3 (DPAK) surface mount configuration
• Supplier device package: TO-252

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes. Variations in secondary parameters such as moisture sensitivity level or specific supplier packaging designations do not affect substitution eligibility when primary electrical and mechanical specifications are identical.

Parameter Comparison

Engineering Selection Recommendations

Both the 2SCR583D3FRATL and 2SCR583D3TL1 are active products from Rohm Semiconductor with identical electrical specifications and mechanical packaging. Selection between these parts is based on availability and supply chain requirements rather than functional differences.

The 2SCR583D3FRATL carries AEC-Q101 automotive qualification and is specified with MSL 3 (168 hours moisture sensitivity). The 2SCR583D3TL1 is specified with MSL 1 (unlimited moisture sensitivity), indicating superior moisture resistance characteristics. Both parts maintain ROHS3 compliance and REACH unaffected status, suitable for regulated applications.

Component selection should prioritize availability from authorized distributors. The 2SCR583D3TL1 offers enhanced moisture handling characteristics for applications requiring extended storage or exposure to humid environments prior to assembly. The 2SCR583D3FRATL remains the primary specification when automotive qualification is explicitly required by design documentation.

Frequently Asked Questions (FAQ)

Q: Can the 2SCR583D3TL1 be used as a direct replacement for the 2SCR583D3FRATL in automotive applications?

A: Yes. Both parts are manufactured by Rohm Semiconductor with identical electrical parameters, power ratings, and TO-252 package specifications. The 2SCR583D3TL1 features improved moisture sensitivity characteristics (MSL 1 versus MSL 3), which provides additional reliability margin in storage and assembly environments.

Q: What is the significance of the different moisture sensitivity levels between these parts?

A: MSL 3 (168 hours) indicates the component can be exposed to ambient conditions of 30°C/60% relative humidity for up to 168 hours before assembly. MSL 1 (unlimited) indicates no time restriction under these conditions. The 2SCR583D3TL1 with MSL 1 provides greater flexibility in inventory management and assembly scheduling without requiring bake-out procedures.

Q: Are the pin configurations identical between 2SCR583D3FRATL and 2SCR583D3TL1?

A: Yes. Both parts use the TO-252-3 (DPAK) package with 2 leads plus tab configuration. Pin assignments, lead spacing, and mounting pad layouts are identical, enabling direct PCB footprint compatibility.

Q: What are the key electrical parameters that define substitution eligibility for this transistor?

A: Substitution eligibility is determined by matching: NPN polarity, 50V maximum collector-emitter breakdown voltage, 7A maximum collector current, 10W maximum power dissipation, 280MHz transition frequency, 180 minimum DC current gain at specified bias conditions, 350mV maximum saturation voltage, and 1µA maximum collector cutoff current.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Yes. Both parts specify 280MHz transition frequency and identical saturation characteristics, supporting equivalent performance in switching circuits operating within the specified frequency range and power envelope.

Q: What compliance certifications apply to both substitute parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The 2SCR583D3FRATL carries AEC-Q101 automotive qualification. Both parts are classified under ECCN EAR99 for export control purposes.
