FS2A-TP Equivalent & Substitute Parts

Part Overview

The FS2A-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 50 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AC (SMA) package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and procurement continuity. The FS2A-TP features fast recovery characteristics with a reverse recovery time of 150 ns, suitable for standard rectification applications requiring moderate current handling at 50 V operation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FS2A-TP is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain a DC reverse voltage rating of 50 V or higher to ensure safe operation within the original circuit design envelope.

Current Rating Compatibility: The substitute part must support an average rectified current rating equal to or greater than 2 A. Higher current ratings provide design margin and do not compromise circuit function.

Package and Mounting Compatibility: The substitute part must use the DO-214AC (SMA) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Speed Classification: The substitute part must maintain fast recovery characteristics (≤ 500ns, > 200mA) to preserve switching performance and minimize reverse recovery losses in the application.

Compliance and Environmental Requirements: The substitute part must meet ROHS3 compliance and maintain MSL 1 (Unlimited) moisture sensitivity classification to satisfy regulatory and manufacturing requirements.

The SBRT5A50SA-13 meets all substitution criteria through equivalent voltage and package specifications, with enhanced current capacity and active product status.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SBRT5A50SA-13 (Diodes Incorporated)

The SBRT5A50SA-13 is the qualified substitute for the obsolete FS2A-TP. Both components share identical voltage ratings (50 V), equivalent package specifications (DO-214AC, SMA), and matching speed classifications (fast recovery ≤ 500ns). The substitute maintains full ROHS3 compliance and MSL 1 classification, satisfying regulatory and manufacturing requirements.

Advantages of Substitution:

The SBRT5A50SA-13 is an active product with confirmed inventory availability (11,100 pcs), eliminating supply chain risk associated with the obsolete FS2A-TP. The substitute provides higher average rectified current capacity (5 A versus 2 A), offering design margin for thermal and electrical stress. The extended operating temperature range (-55°C to 150°C versus -50°C to 150°C) provides broader environmental compatibility.

Design Considerations:

The SBRT5A50SA-13 exhibits higher reverse leakage current (150 µA @ 50 V versus 5 µA @ 50 V). Applications sensitive to leakage current performance must evaluate this parameter against circuit requirements. The substitute uses Super Barrier technology (TrenchSBR series), which may introduce minor differences in forward voltage characteristics compared to the standard technology of the original part. Forward voltage specification for the substitute is provided at 530 mV @ 5 A; the original part forward voltage is not specified in the input data.

Both components are surface mount devices in identical packages, ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the SBRT5A50SA-13 directly replace the FS2A-TP in existing designs?

A: Yes. Both components share the same 50 V voltage rating, DO-214AC (SMA) package, and fast recovery speed classification. Direct substitution is mechanically and electrically compatible at the package level. Circuit-level validation is required to confirm that the higher reverse leakage current (150 µA versus 5 µA) does not impact application performance.

Q: Why does the substitute have a higher current rating (5 A versus 2 A)?

A: The SBRT5A50SA-13 is designed for higher current applications. In circuits requiring only 2 A, the higher rating provides thermal margin and reduces component stress, extending operational life. The 50 V voltage rating remains the limiting parameter for both devices.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both the FS2A-TP and SBRT5A50SA-13 are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are assigned ECCN EAR99 and HTSUS 8541.10.0080 codes. Compliance requirements are equivalent.

Q: What is the significance of the "Super Barrier" technology in the SBRT5A50SA-13?

A: Super Barrier technology is a manufacturing approach used by Diodes Incorporated in their TrenchSBR series to optimize forward voltage and reverse recovery characteristics. This technology does not affect substitution compatibility but may result in minor differences in forward voltage performance compared to standard rectifier technology.

Q: Is the reverse recovery time specification available for the SBRT5A50SA-13?

A: The reverse recovery time (trr) is not specified in the provided data for the SBRT5A50SA-13. Both devices meet the fast recovery classification (≤ 500ns, > 200mA). For applications requiring specific trr values, detailed datasheets from Diodes Incorporated must be consulted.

Q: Why is the FS2A-TP classified as obsolete?

A: Obsolete status indicates that Micro Commercial Co has discontinued manufacturing and support for this component. The SBRT5A50SA-13 is an active product with ongoing manufacturing and supply availability, making it the appropriate long-term solution for new designs and ongoing production.

Q: Are there packaging format differences between the two parts?

A: The FS2A-TP is supplied in standard packaging. The SBRT5A50SA-13 is available in Cut Tape (CT) and Digi-Reel® formats, providing flexibility for different manufacturing and procurement workflows. Both use the same DO-214AC (SMA) component package.
