FR203G Equivalent & Substitute Parts

Part Overview

The FR203G is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 200 V DC reverse voltage and 2 A average rectified current. The device is packaged in a DO-204AC (DO-15) axial through-hole configuration and is classified as a fast recovery diode with a reverse recovery time of 150 ns. This component is actively produced and maintains full RoHS3 compliance.

Equivalent and substitute parts are identified to provide design flexibility, support supply chain continuity, and accommodate varying packaging or inventory requirements while maintaining electrical and mechanical compatibility within the specified parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the FR203G are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Voltage Rating: DC reverse voltage (Vr) must equal 200 V
Current Rating: Average rectified current (Io) must equal 2 A
Forward Voltage: Forward voltage drop (Vf) at rated current must not exceed 1.3 V @ 2 A
Recovery Characteristics: Reverse recovery time (trr) must equal 150 ns with fast recovery speed classification (≤ 500ns, > 200mA)
Package Compatibility: Through-hole axial package (DO-204AC / DO-15)
Temperature Range: Operating junction temperature range must span -55°C to 150°C
Compliance: RoHS3 compliance required

The PG202R_R2_00001 manufactured by Panjit International Inc. meets all specified electrical parameters and mechanical requirements for direct substitution with the FR203G.

Engineering Selection Recommendations

Both the FR203G and PG202R_R2_00001 are active production components with full RoHS3 compliance and REACH unaffected status. The electrical parameters are identical across all critical specifications: reverse voltage, forward current, forward voltage drop, and reverse recovery time.

The PG202R_R2_00001 exhibits lower reverse leakage current (1 µA versus 5 µA at 200 V), which represents an improvement in leakage performance and may provide enhanced reliability in applications sensitive to reverse leakage characteristics.

Both devices are suitable for direct substitution in through-hole applications requiring 200 V, 2 A fast recovery rectification. Selection between these parts may be based on availability, packaging format (Cut Tape versus standard packaging), or specific leakage current requirements.

Frequently Asked Questions (FAQ)

Q: Can the PG202R_R2_00001 be used as a direct replacement for the FR203G?

A: Yes. Both devices share identical electrical ratings (200 V, 2 A, 1.3 V forward drop, 150 ns recovery time) and are packaged in compatible through-hole DO-15 axial configurations. Both maintain RoHS3 compliance and identical operating temperature ranges.

Q: What is the difference in reverse leakage current between these parts?

A: The FR203G specifies 5 µA reverse leakage at 200 V, while the PG202R_R2_00001 specifies 1 µA at the same voltage. The lower leakage of the PG202R_R2_00001 is compatible with FR203G applications and may be advantageous in circuits where leakage current is a design consideration.

Q: Are the packages physically identical?

A: Both parts use DO-204AC (DO-15) axial through-hole packages. Physical dimensions and lead spacing are compatible for PCB mounting. The PG202R_R2_00001 is supplied in Cut Tape packaging, while the FR203G packaging format is not specified in the provided data.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the FR203G and PG202R_R2_00001 are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8541.10.0080).

Q: What is the operating temperature range for both devices?

A: Both devices operate across a junction temperature range of -55°C to 150°C, providing identical thermal performance specifications.

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

A: Yes. The electrical and mechanical parameters are equivalent, allowing direct substitution in circuit designs without modification to PCB layouts or schematic connections.
