FR2J-LTP Equivalent & Substitute Parts

Part Overview

The FR2J-LTP is a general-purpose 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 component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory availability, supply chain considerations, or specific application requirements within the allowed parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR2J-LTP are qualified based on the following criteria:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 2 A
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts meet these mandatory electrical and mechanical requirements. Variations in secondary parameters such as forward voltage (Vf), reverse recovery time (trr), reverse leakage current, and junction temperature range are permitted within the scope of general-purpose rectifier diode applications, provided the primary ratings remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

FR2J-LTP (Micro Commercial Co): Primary selection for standard general-purpose rectifier applications. Active product status with established supply chain. RoHS3 compliant and MSL 1 rated for unlimited moisture exposure.

ES2LJH (Taiwan Semiconductor Corporation): Qualified substitute with automotive-grade qualification (AEC-Q101) and extended lower junction temperature rating (-55°C). Forward voltage specification is higher at 1.7 V @ 2 A compared to 1.3 V, and reverse recovery time is significantly faster at 35 ns. Suitable for applications requiring automotive-grade components or enhanced thermal performance at lower temperatures. Higher inventory availability (7044 pcs).

FR2J_R1_00001 (Panjit International Inc.): Parametric equivalent with identical forward voltage (1.3 V @ 2 A) and reverse recovery time (250 ns) to the FR2J-LTP. Reverse leakage current is superior at 1 µA @ 600 V. Suitable for direct substitution in applications where forward voltage and recovery characteristics are critical. Active product status with moderate inventory (3166 pcs).

All three parts are RoHS3 compliant, MSL 1 rated, and maintain identical voltage and current ratings. Selection between substitutes depends on specific application requirements regarding forward voltage drop, recovery time performance, temperature range, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can ES2LJH replace FR2J-LTP in all applications?

A: ES2LJH meets the mandatory electrical and mechanical requirements (600 V, 2 A, DO-214AA SMB package). However, the forward voltage is specified at 1.7 V @ 2 A compared to 1.3 V for FR2J-LTP. Applications sensitive to forward voltage drop or power dissipation must evaluate this 0.4 V difference. Reverse recovery time is faster (35 ns vs. 250 ns), which may benefit high-frequency switching applications.

Q: What is the difference between FR2J_R1_00001 and FR2J-LTP?

A: FR2J_R1_00001 is a parametric equivalent manufactured by Panjit International Inc. Both parts share identical forward voltage (1.3 V @ 2 A), reverse recovery time (250 ns), and operating temperature range (-50°C ~ 150°C). The primary difference is reverse leakage current: FR2J_R1_00001 specifies 1 µA @ 600 V versus 5 µA for FR2J-LTP. Both are suitable for direct substitution in general-purpose rectifier applications.

Q: Are all substitute parts surface mount in DO-214AA packaging?

A: Yes. All three parts—FR2J-LTP, ES2LJH, and FR2J_R1_00001—are surface mount devices in DO-214AA (SMB) package format. Mechanical compatibility with PCB layouts and reflow soldering processes is maintained across all substitutes.

Q: What does RoHS3 compliance mean for these diodes?

A: RoHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive, restricting the use of specified hazardous materials including lead, cadmium, mercury, and certain flame retardants. All three substitute parts meet this regulatory requirement.

Q: Is MSL 1 rating important for these components?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited moisture exposure tolerance. These diodes do not require special moisture-control handling during storage, transportation, or assembly. Standard warehouse and manufacturing conditions are acceptable.

Q: Can I use ES2LJH in a temperature-critical application requiring -55°C operation?

A: ES2LJH specifies an operating junction temperature range of -55°C ~ 150°C, extending 5°C lower than FR2J-LTP (-50°C ~ 150°C). If your application requires operation at -55°C, ES2LJH is the appropriate selection among the three options.

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

A: Reverse recovery time (trr) affects switching speed and switching losses in rectifier applications. FR2J-LTP and FR2J_R1_00001 both specify 250 ns, while ES2LJH specifies 35 ns. Faster recovery reduces switching losses in high-frequency applications but may increase electromagnetic noise. Application frequency requirements determine the appropriate selection.
