FR2J-TP Equivalent & Substitute Parts

Part Overview

The FR2J-TP is a general-purpose fast recovery rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 2 A average rectified current in a surface mount DO-214AA (SMB) package. This part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement continuity. The FR2J-TP operates across a junction temperature range of -50°C to 150°C and complies with RoHS3 standards with unlimited moisture sensitivity level (MSL 1).

Substitute Part Grouping Explanation

Substitution eligibility for the FR2J-TP is determined by the following critical parameters:

Primary Matching Criteria:

Voltage - DC Reverse (Vr) (Max): 600 V
Current - Average Rectified (Io): 2 A
Package / Case: DO-214AA, SMB (surface mount)
Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Secondary Compatibility Factors:

Reverse Recovery Time (trr): 250 ns (FR2J-TP specification)
Reverse Leakage Current: 5 µA @ 600 V
Operating Temperature Range: -50°C to 150°C
RoHS3 Compliance

The FR2J-TP has two identified substitutes: FR2J-LTP (direct manufacturer equivalent from Micro Commercial Co) and STTH2R06U (cross-manufacturer equivalent from STMicroelectronics). Both maintain the core electrical ratings and package form factor required for direct replacement in circuit applications.

Engineering Selection Recommendations

FR2J-LTP (Micro Commercial Co)

The FR2J-LTP is the primary substitute for the obsolete FR2J-TP. Both parts share identical electrical ratings (600 V, 2 A, 250 ns reverse recovery time) and operate within the same junction temperature range (-50°C to 150°C). The FR2J-LTP maintains active product status with current manufacturing availability. Forward voltage specification (1.3 V @ 2 A) is lower than the STTH2R06U alternative, resulting in reduced power dissipation in rectification applications. Both parts are RoHS3 compliant with MSL 1 rating. The FR2J-LTP is supplied in Tape & Reel packaging format.

STTH2R06U (STMicroelectronics)

The STTH2R06U is a cross-manufacturer equivalent offering superior reverse recovery time performance (50 ns versus 250 ns) and lower reverse leakage current (2 µA versus 5 µA @ 600 V). This part maintains the same 600 V / 2 A ratings and DO-214AA SMB package form factor. The STTH2R06U supports an extended upper junction temperature limit of 175°C compared to 150°C for the FR2J-TP and FR2J-LTP. Forward voltage is higher at 1.7 V @ 2 A. The part is RoHS3 compliant with MSL 1 rating and is supplied in Cut Tape and Digi-Reel packaging. The improved reverse recovery time and lower leakage current make this part suitable for applications requiring enhanced switching performance.

Frequently Asked Questions (FAQ)

Q: Can FR2J-LTP directly replace FR2J-TP in existing designs?

A: Yes. The FR2J-LTP is a direct equivalent with identical voltage (600 V), current (2 A), reverse recovery time (250 ns), and operating temperature range (-50°C to 150°C) specifications. Both use the same DO-214AA SMB package for surface mount applications. The primary difference is product status: FR2J-TP is obsolete while FR2J-LTP is active production.

Q: What are the performance differences between FR2J-LTP and STTH2R06U?

A: The STTH2R06U offers faster reverse recovery time (50 ns versus 250 ns) and lower reverse leakage current (2 µA versus 5 µA @ 600 V). Forward voltage is higher for STTH2R06U (1.7 V @ 2 A versus 1.3 V @ 2 A). The STTH2R06U supports higher maximum junction temperature (175°C versus 150°C). All three parts maintain identical 600 V / 2 A ratings and DO-214AA SMB package compatibility.

Q: Are all three parts RoHS3 compliant?

A: Yes. FR2J-TP, FR2J-LTP, and STTH2R06U are all RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating.

Q: What packaging formats are available for these substitutes?

A: FR2J-TP is supplied in standard packaging (format not specified). FR2J-LTP is supplied in Tape & Reel (TR) format. STTH2R06U is supplied in Cut Tape (CT) and Digi-Reel packaging formats.

Q: Which substitute should be selected for high-temperature applications?

A: The STTH2R06U supports junction temperatures up to 175°C, compared to 150°C maximum for both FR2J-TP and FR2J-LTP. For applications requiring operation above 150°C, STTH2R06U is the appropriate selection.

Q: Are there any differences in capacitance specifications?

A: FR2J-TP specifies 40 pF @ 4V, 1MHz. FR2J-LTP specifies 50 pF @ 4V, 1MHz. STTH2R06U does not provide capacitance specification in the available data.
