Substitute Part Grouping Explanation

Substitute parts for the 2A02GHR0G are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalent (2A02GH): Identical electrical specifications and package format. This part maintains all key parameters including 100 V reverse voltage, 2 A average rectified current, 1.1 V forward voltage at 2 A, standard recovery speed, and DO-204AC packaging. Product status is Active, providing immediate availability.

Similar Substitutes (EGP20B, EGP20B-E3/54, EGP20B-E3/73): These Fairchild Semiconductor and Vishay parts share the same voltage and current ratings (100 V, 2 A) and package format (DO-204AC/DO-15). Key difference: these parts feature fast recovery speed (≤500ns) versus the standard recovery (>500ns) of the original part. Forward voltage is reduced to 950 mV @ 2 A. Operating temperature range extends to -65°C. These parts are suitable where improved switching characteristics are acceptable.

Lower Current Alternatives (GP15B-E3/54, GP15B-E3/73, RGP15B-E3/54, RGP15B-E3/73): These Vishay SUPERECTIFIER® parts maintain 100 V reverse voltage and DO-204AC packaging but are rated for 1.5 A average rectified current. These are suitable only for applications where the 2 A current requirement can be reduced or where redundant parallel configurations are implemented.

Parametric Equivalents (GPP20B-E3/54, PG201_R2_00001): These parts match all critical parameters of the original 2A02GHR0G: 100 V reverse voltage, 2 A average rectified current, 1.1 V forward voltage at 2 A, standard recovery speed, and DO-204AC/DO-15 packaging. Manufacturers are Vishay and Panjit International respectively. Both are Active status with full compliance certifications.

Engineering Selection Recommendations

Primary Recommendation: 2A02GH

The 2A02GH from Taiwan Semiconductor Corporation is the direct equivalent replacement. It maintains identical electrical specifications (100 V, 2 A, 1.1 V forward voltage, standard recovery speed) and package format (DO-204AC). This part is Active status with full AEC-Q101 automotive qualification and ROHS3 compliance, matching the original part's certifications. Inventory availability is 1074 pieces.

Secondary Recommendations: GPP20B-E3/54 and PG201_R2_00001

Both parts are parametric equivalents with identical electrical performance to the original 2A02GHR0G. GPP20B-E3/54 (Vishay, 8652 pieces in stock) and PG201_R2_00001 (Panjit International, 727 pieces in stock) maintain the same voltage, current, forward voltage, and recovery speed specifications. Both are Active status with ROHS3 compliance and AEC-Q101 qualification. These parts are suitable for direct substitution in applications where the original specifications are required.

Alternative for Enhanced Switching Performance: EGP20B-E3/73

The EGP20B-E3/73 from Vishay provides the same 100 V, 2 A ratings in DO-204AC packaging but with fast recovery characteristics (50 ns reverse recovery time) and reduced forward voltage (950 mV @ 2 A). This part is suitable for applications where improved switching efficiency is beneficial. Extended operating temperature range (-65°C to 150°C) provides additional margin. Inventory is 42995 pieces. This substitution requires confirmation that the fast recovery characteristic does not introduce switching noise or EMI concerns in the target application.

Not Recommended for Direct Substitution: GP15B and RGP15B Series

The GP15B-E3/54, GP15B-E3/73, RGP15B-E3/54, and RGP15B-E3/73 parts are rated for 1.5 A average rectified current, which is below the 2 A specification of the original part. These parts are suitable only for applications where current requirements have been reduced or where parallel configurations are implemented to achieve the required current capacity.

Frequently Asked Questions (FAQ)

Q: Can the 2A02GH be used as a direct replacement for the 2A02GHR0G?

A: Yes. The 2A02GH is a direct equivalent with identical electrical specifications and package format.

A: The EGP20B series (EGP20B, EGP20B-E3/54, EGP20B-E3/73) maintains the same voltage and current ratings but features fast recovery speed (≤500ns with 50 ns reverse recovery time) compared to the standard recovery (>500ns) of the original part. Forward voltage is reduced to 950 mV @ 2 A. These parts are suitable where improved switching characteristics are acceptable and do not introduce EMI concerns.

Q: Can the GP15B or RGP15B parts replace the 2A02GHR0G?

A: The GP15B and RGP15B series are rated for 1.5 A average rectified current, which is below the 2 A specification of the original part. These parts are not suitable for direct substitution in applications requiring the full 2 A current capacity. They may be used only in applications where current requirements have been reduced or in parallel configurations.

Q: Are all substitute parts automotive qualified?

A: The 2A02GH, GPP20B-E3/54, and PG201_R2_00001 maintain AEC-Q101 automotive qualification matching the original part. The EGP20B series and GP15B/RGP15B series are Active status with ROHS3 compliance but do not explicitly list AEC-Q101 qualification in the provided specifications. Verification of automotive qualification requirements for the target application is necessary.

Q: What is the difference between DO-204AC and DO-15 package designations?

A: DO-204AC and DO-15 refer to the same axial through-hole package format. Both designations are used interchangeably in the industry. All substitute parts listed are compatible with the original DO-204AC package footprint.

Q: Which substitute part has the highest inventory availability?

A: The EGP20B-E3/73 from Vishay has the highest inventory with 42995 pieces in stock. This part is suitable for applications where fast recovery characteristics are acceptable.

Q: What is the operating temperature range difference between substitutes?

A: The original 2A02GHR0G and its direct equivalents (2A02GH, GPP20B-E3/54, PG201_R2_00001) operate from -55°C to 150°C. The EGP20B series and GP15B/RGP15B series extend the lower temperature limit to -65°C. The GP15B and RGP15B series extend the upper temperature limit to 175°C. Selection depends on the target application's thermal requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the original part's environmental compliance status.
