Equivalent & Substitute Parts for 2SAR293PFRAT100

Part Overview

The 2SAR293PFRAT100, manufactured by Rohm Semiconductor, is an automotive-grade PNP bipolar junction transistor (BJT) in the TO-243AA (MPT3) surface-mount package. It features a 30 V collector-emitter voltage, 1 A collector current, 320 MHz transition frequency, and a 500 mW power rating. As an active component with RoHS3 and AEC-Q101 (automotive qualification), substitute or equivalent parts may be needed for purposes such as inventory availability, supply chain management, or alternative packaging requirements.

Substitute Part Grouping Explanation

Substitute part selection is based strictly on matching the following key electrical and mechanical parameters: transistor type (PNP), collector-emitter voltage (30 V), maximum collector current (1 A), maximum power dissipation (500 mW), transition frequency (320 MHz), current gain (hFE) minimum, Vce saturation, collector cutoff current, case/package, and automotive qualification. Only parts with identical or matching values in these parameters are considered equivalent within the “Transistors, Bipolar (BJT)” product category.

Engineering Selection Recommendations

All parts listed—2SAR293PFRAT100, 2SAR293P5T100, and 2SAR293PHZGT100—carry an active product status and ROHS3 compliance. The 2SAR293PFRAT100 and 2SAR293PHZGT100 have explicit AEC-Q101 automotive qualification stated; the 2SAR293P5T100 does not. Each part is suitable for use when matching the specified electrical and thermal parameters, while package differences should be considered according to socket and layout requirements. Moisture Sensitivity Level (MSL) and REACH compliance are consistent across all models.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for substitution among 2SAR293PFRAT100, 2SAR293P5T100, and 2SAR293PHZGT100?
A1: Core required parameters for equivalence are transistor type (PNP), collector-emitter voltage (30 V), collector current (1 A), power dissipation (500 mW), transition frequency (320 MHz), Vce saturation, current gain (hFE), collector cutoff current, compliance status, and package specification.

Q2: Are all listed substitutes AEC-Q101 qualified for automotive use?
A2: The 2SAR293PFRAT100 and 2SAR293PHZGT100 are AEC-Q101 qualified. The qualification for 2SAR293P5T100 is not specified.

Q3: How do package differences affect substitution?
A3: The 2SAR293PFRAT100 and 2SAR293P5T100 use the MPT3 package, while the 2SAR293PHZGT100 is supplied as SOT-89. Mechanical compatibility with the target PCB layout must be verified.
