Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FR155GP-AP are identified based on the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain the same maximum DC reverse voltage rating of 600 V to ensure safe operation within the intended circuit application.

Package Compatibility: The substitute part must use the DO-204AC/DO-15 axial through-hole package format to ensure mechanical fit and PCB mounting compatibility.

Operating Temperature Range: The substitute part must support the full operating junction temperature range of -55°C to 150°C.

Regulatory Compliance: The substitute part must maintain RoHS3 compliance and REACH unaffected status to satisfy environmental and regulatory requirements.

Current Rating Consideration: While the FR155GP-AP is rated for 1.5 A average rectified current, substitute parts with equal or higher current ratings (2 A or greater) are acceptable for applications where the circuit design does not exceed the original component's current specification.

Parameter Comparison

Engineering Selection Recommendations

The GPP20J-E3/54 manufactured by Vishay General Semiconductor - Diodes Division is a qualified substitute for the FR155GP-AP based on the following criteria:

Voltage and Current Ratings: Both components are rated for 600 V DC reverse voltage. The GPP20J-E3/54 provides a higher current rating of 2 A compared to the FR155GP-AP's 1.5 A rating. This higher rating does not create incompatibility; circuits designed for 1.5 A operation remain within the safe operating limits of the substitute part.

Package and Mounting: Both components utilize the DO-204AC/DO-15 axial through-hole package format, ensuring identical PCB footprint and mechanical compatibility.

Temperature Range: Both components support the identical operating junction temperature range of -55°C to 150°C, maintaining thermal performance across all application environments.

Regulatory Compliance: Both components are RoHS3 compliant and REACH unaffected, satisfying all environmental and regulatory requirements for equivalent component selection.

Product Status: Both components maintain Active product status, ensuring continued availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can the GPP20J-E3/54 be used as a direct replacement for the FR155GP-AP in all applications?

A: The GPP20J-E3/54 is electrically and mechanically compatible with the FR155GP-AP for applications where the circuit current requirement does not exceed 1.5 A. The substitute part's higher 2 A current rating provides additional design margin without creating operational conflicts. Both components share identical voltage ratings, package format, and operating temperature range.

Q: What is the significance of the different forward voltage specifications between these parts?

A: The FR155GP-AP specifies a maximum forward voltage of 1.3 V at 1.5 A, while the GPP20J-E3/54 specifies 1.1 V at 2 A. These measurements are taken at different current levels and represent the maximum values for each part at their respective rated currents. The lower forward voltage of the substitute part indicates improved efficiency characteristics at higher current levels.

Q: Are there package compatibility concerns when substituting these parts?

A: No. Both the FR155GP-AP and GPP20J-E3/54 use the DO-204AC/DO-15 axial through-hole package format. The physical dimensions, lead spacing, and mounting requirements are identical, ensuring direct PCB compatibility without layout modifications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both components are RoHS3 compliant and REACH unaffected. They share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications, satisfying all environmental and trade compliance requirements.

Q: What is the difference in recovery speed between these diodes?

A: The FR155GP-AP is classified as a fast recovery diode with a reverse recovery time of 250 ns. The GPP20J-E3/54 is classified as a standard recovery diode with recovery time exceeding 500 ns. For applications requiring fast switching characteristics, the FR155GP-AP maintains superior performance. For general-purpose rectification applications, the standard recovery speed of the substitute part is functionally adequate.

Q: Can the GPP20J-E3/54 be used in high-frequency switching applications designed for the FR155GP-AP?

A: The GPP20J-E3/54's standard recovery speed (>500 ns) differs from the FR155GP-AP's fast recovery specification (250 ns). Applications requiring fast switching transitions or operating at high frequencies should retain the FR155GP-AP. The substitute part is suitable for standard rectification and lower-frequency applications.
