Equivalent & Substitute Parts for 2SCR574D3FRATL

Part Overview

The 2SCR574D3FRATL from Rohm Semiconductor is an NPN bipolar junction transistor (BJT) in the Transistors, Bipolar (BJT) category. It is designed for automotive applications requiring high reliability, with features that include a maximum collector current of 2 A, collector-emitter breakdown voltage of 80 V, and a 10 W power capability in a surface mount TO-252 package. The device is rated for operation up to 150°C and is characterized by an hFE (DC current gain) of at least 120 at specified test conditions. The part complies with ROHS3, REACH, and AEC-Q101 standards, ensuring suitability for high-performance and automotive-grade designs.

Identifying alternative models, such as parametric or equivalent parts, is essential for maintaining supply chain continuity, ensuring rapid design-in during shortages, supporting multi-sourcing strategies, or accommodating packaging format requirements, while staying within the certified and validated parameters critical to the design intent.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined using the following critical parameters: NPN transistor configuration, maximum collector-emitter voltage (80 V), maximum collector current (2 A), minimum DC current gain (hFE) at defined test conditions (120 at 100mA/3V), maximum allowable power dissipation (10 W), Vce saturation voltage (300mV @ 50mA, 1A), collector cutoff current (1µA ICBO), transition frequency (280MHz), surface mount package type (TO-252-3, DPAK), automotive qualification (AEC-Q101), and compliance (ROHS3, REACH). Only parametric matches within these specifications are included as substitution candidates.

Parameter Comparison

Engineering Selection Recommendations

Both 2SCR574D3FRATL and 2SCR574D3TL1 are active products with identical key electrical and mechanical parameters, identical compliance with ROHS3 and REACH, and meet AEC-Q101 automotive-grade qualification. Both parts are provided in the same package type and mounting style. Selection between these models can be based on packaging format or inventory availability, as all provided technical, qualification, and compliance parameters are matched.

Frequently Asked Questions (FAQ)

Q: What are the necessary criteria for substituting the 2SCR574D3FRATL with another part?
A: Substitution requires matching transistor type (NPN), collector-emitter voltage, collector current, power rating, DC current gain, saturation voltage, cutoff current, transition frequency, case/package, compliance standards, and qualification (AEC-Q101 for automotive).

Q: Is mechanical form factor important in BJT substitution?
A: Yes, the mounting type and package/case (TO-252-3, DPAK) must be identical to ensure compatibility with existing PCB footprints and system assembly processes.

Q: How does compliance affect substitute selection?
A: ROHS3 and REACH compliance are mandatory for environmental safety and import/export legality, while AEC-Q101 is required for automotive reliability.

Q: Are there any differences between 2SCR574D3FRATL and 2SCR574D3TL1?
A: Based on provided parameters, there are no differences in key electrical, mechanical, or compliance-related specifications.

Q: Can substitute selection be based on packaging or inventory if all parameters match?
A: Yes, provided all listed technical, qualification, and compliance parameters are identical, packaging format or inventory levels can determine final selection.
