FR2D-TP Equivalent & Substitute Parts

Part Overview

The FR2D-TP is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 200 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support and procurement continuity. The diode features fast recovery characteristics with a reverse recovery time of 150 ns and operates across a junction temperature range of -50°C to 150°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FR2D-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage rating of 200 V or higher to ensure safe operation in the original circuit.

Current Rating: The substitute part must support an average rectified current of 2 A or greater.

Package and Mounting: The substitute part must use the DO-214AA (SMB) surface mount package to ensure mechanical and thermal compatibility with existing PCB layouts.

Speed Classification: The substitute part must meet or exceed the fast recovery classification (≤ 500ns for currents > 200mA) to maintain switching performance characteristics.

Temperature Range: The substitute part must support the operating junction temperature range of the original application.

The MURS120/2 manufactured by Vishay General Semiconductor - Diodes Division meets all substitution criteria for the FR2D-TP.

Parameter Comparison

Engineering Selection Recommendations

The MURS120/2 is a direct functional substitute for the FR2D-TP based on electrical and mechanical parameter equivalence. Both devices share identical voltage and current ratings, package configuration, and fast recovery speed classification. The MURS120/2 demonstrates superior performance characteristics with a reverse recovery time of 35 ns compared to 150 ns for the FR2D-TP, and lower reverse leakage current of 2 µA versus 5 µA.

The MURS120/2 is currently in active production status, ensuring long-term availability and supply chain continuity. The operating temperature range of the MURS120/2 (-65°C to 175°C) exceeds the FR2D-TP range (-50°C to 150°C), providing extended thermal operating capability.

Design teams should note the RoHS compliance difference: the FR2D-TP is ROHS3 compliant while the MURS120/2 is RoHS non-compliant. This distinction is relevant for applications subject to RoHS regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the MURS120/2 be used as a direct replacement for the FR2D-TP in existing designs?

A: Yes. Both devices share identical voltage ratings (200 V), current ratings (2 A), package configuration (DO-214AA, SMB), and speed classification (fast recovery ≤ 500ns). The MURS120/2 is mechanically and electrically compatible with PCB layouts designed for the FR2D-TP.

Q: What are the performance differences between the FR2D-TP and MURS120/2?

A: The MURS120/2 exhibits faster reverse recovery time (35 ns versus 150 ns) and lower reverse leakage current (2 µA versus 5 µA). The MURS120/2 also supports a wider operating temperature range (-65°C to 175°C versus -50°C to 150°C).

Q: Are there any compliance considerations when substituting the MURS120/2 for the FR2D-TP?

A: Yes. The FR2D-TP is ROHS3 compliant while the MURS120/2 is RoHS non-compliant. Applications requiring RoHS compliance must account for this difference in material composition and regulatory status.

Q: Does the DO-214AA package ensure mechanical compatibility?

A: Yes. Both the FR2D-TP and MURS120/2 use the DO-214AA (SMB) surface mount package. This ensures identical PCB footprint, solder pad configuration, and thermal interface characteristics.

Q: What is the significance of the reverse recovery time difference?

A: The MURS120/2 reverse recovery time of 35 ns is significantly faster than the FR2D-TP at 150 ns. This results in reduced switching losses and improved efficiency in high-frequency switching applications. The faster recovery time is a performance advantage in the substitute part.

Q: Is the MURS120/2 available in alternative package configurations?

A: The MURS120/2 is specified in the DO-214AA (SMB) package. Related part numbers in the MURS120 family include MURS120-E3/5BT, MURS120-13-F, and MURS220T3G, which may offer different packaging or voltage rating options for alternative applications.
