Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR2G are identified through parametric equivalence based on the following critical electrical and mechanical criteria:

Primary Matching Criteria:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 2 A
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 2 A
• Reverse Recovery Time (trr): 150 ns
• Operating Temperature - Junction: -50°C to 150°C

Substitute Parts Identified:

1. ES2G (YAGEO): Parametric equivalent meeting voltage and package specifications. Active product status with RoHS3 compliance and MSL 1 rating.

2. FR2G_R1_00001 (Panjit International Inc.): Full parametric equivalent with identical electrical ratings (400 V, 2 A, 1.3 V forward voltage, 150 ns recovery time) and DO-214AA SMB package. Active product status with RoHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

FR2G_R1_00001 (Panjit International Inc.) is the primary substitute for the FR2G. This part demonstrates full parametric equivalence across all specified electrical characteristics, including reverse voltage (400 V), average rectified current (2 A), forward voltage (1.3 V @ 2 A), and reverse recovery time (150 ns). Both parts share identical package specifications (DO-214AA, SMB), operating temperature range (-50°C to 150°C), and compliance certifications (RoHS3, MSL 1, EAR99, HTSUS 8541.10.0080). The FR2G_R1_00001 exhibits lower reverse leakage current (1 µA versus 5 µA) and reduced capacitance (40 pF versus 50 pF), representing improved performance characteristics within the same functional class.

ES2G (YAGEO) is a parametric equivalent meeting the critical voltage and package requirements (400 V, DO-214AA SMB). This part maintains Active product status, RoHS3 compliance, and MSL 1 rating. However, ES2G specifications do not include detailed current, recovery time, and temperature range parameters in the provided data. ES2G is suitable for applications where the primary selection criteria are voltage rating and package compatibility.

All three parts are Active products with RoHS3 compliance and unlimited moisture sensitivity level, ensuring regulatory and environmental compliance across substitution options.

Frequently Asked Questions (FAQ)

Q: Can ES2G directly replace FR2G in all applications?

A: ES2G meets the primary voltage (400 V) and package (DO-214AA SMB) specifications for the FR2G. However, ES2G does not provide detailed specifications for average rectified current, reverse recovery time, and operating temperature range. Substitution is valid for applications where these parameters are not critical design constraints.

Q: What is the difference between FR2G and FR2G_R1_00001?

A: Both parts are electrically equivalent with identical ratings for reverse voltage (400 V), average rectified current (2 A), forward voltage (1.3 V @ 2 A), and reverse recovery time (150 ns). FR2G_R1_00001 demonstrates superior performance with lower reverse leakage current (1 µA versus 5 µA) and reduced junction capacitance (40 pF versus 50 pF). Both parts use the same DO-214AA SMB package and share identical compliance certifications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. FR2G, ES2G, and FR2G_R1_00001 are all RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, ensuring compatibility with lead-free assembly processes and environmental regulations.

Q: What package type is used for these diodes?

A: All parts use the DO-214AA surface mount package, commonly designated as SMB. This package is suitable for automated pick-and-place assembly on printed circuit boards.

Q: Are there temperature range differences between substitute parts?

A: FR2G and FR2G_R1_00001 both specify an operating junction temperature range of -50°C to 150°C. ES2G does not provide detailed temperature specifications in the available data.

Q: What is the significance of reverse recovery time (trr) for these diodes?

A: Reverse recovery time (150 ns for FR2G and FR2G_R1_00001) indicates fast recovery performance, suitable for high-frequency rectification applications. This parameter is critical for switching speed and efficiency in power conversion circuits.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All substitute parts share the DO-214AA SMB package footprint, enabling direct PCB layout compatibility without design modifications. Electrical equivalence across voltage, current, and thermal specifications ensures functional interchangeability.
