Substitute Part Grouping Explanation

Substitute parts for the FR303GP-TP are identified based on strict parametric equivalence within the general-purpose rectifier diode category. The substitution logic is based on the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 200 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 3 A
• Reverse Recovery Time (trr): 150 ns
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Standard

Allowable Parameter Variations:

• Current - Reverse Leakage @ Vr: May vary within acceptable limits (1–5 µA @ 200 V)
• Capacitance @ Vr, F: May vary (30–60 pF @ 4V, 1MHz)

Parts meeting these criteria are classified as parametric equivalents and direct substitutes for the FR303GP-TP in applications requiring 200V, 3A general-purpose rectification with fast recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

FR303G (Taiwan Semiconductor Corporation): This substitute is an active product with full parametric equivalence to the FR303GP-TP. It meets all mandatory electrical specifications and maintains identical voltage, current, and recovery time ratings. The FR303G is suitable for direct replacement in applications where the original FR303GP-TP is no longer procurable. Its active product status ensures ongoing availability and supply chain continuity.

PG302R_R2_00001 (Panjit International Inc.): This substitute is an active product offering parametric equivalence with a notable improvement in reverse leakage current (1 µA versus 5 µA @ 200 V), resulting in lower leakage losses. The PG302R_R2_00001 is supplied in Tape & Reel packaging, matching the original FR303GP-TP packaging format. This part is suitable for direct replacement and offers enhanced performance characteristics in leakage-sensitive applications.

Both substitute parts are ROHS3 compliant and maintain the same operating temperature range as the original component. Selection between FR303G and PG302R_R2_00001 depends on packaging requirements and leakage current specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can FR303G be used as a direct replacement for FR303GP-TP?

A: Yes. The FR303G meets all mandatory electrical parameters: 200V reverse voltage, 3A average rectified current, 1.3V forward voltage at 3A, 150ns reverse recovery time, and DO-201AD axial through-hole package. It is electrically and mechanically compatible for direct substitution.

Q: What is the difference between FR303G and PG302R_R2_00001?

A: Both parts are parametric equivalents with identical voltage, current, and recovery time specifications. The primary differences are: (1) PG302R_R2_00001 has lower reverse leakage current (1 µA versus 5 µA @ 200 V), (2) PG302R_R2_00001 is supplied in Tape & Reel packaging matching the original FR303GP-TP format, and (3) they are manufactured by different suppliers (Panjit versus Taiwan Semiconductor Corporation).

Q: Are the substitute parts available in the same packaging as the original FR303GP-TP?

A: The FR303GP-TP is supplied in Tape & Reel (TR) packaging. The PG302R_R2_00001 is also supplied in Tape & Reel packaging. The FR303G packaging format is not specified in the available data. For applications requiring Tape & Reel packaging, PG302R_R2_00001 is the recommended choice.

Q: Do the substitute parts have the same temperature operating range?

A: Yes. Both FR303G and PG302R_R2_00001 operate across the same junction temperature range as the original FR303GP-TP: -55°C to 150°C.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both FR303G and PG302R_R2_00001 are ROHS3 compliant, matching the compliance status of the original FR303GP-TP.

Q: Why is the FR303GP-TP marked "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status and is no longer recommended for new product development. However, it remains available for legacy system support and repair applications. The substitute parts FR303G and PG302R_R2_00001 are active products suitable for both new designs and legacy applications.

Q: What is the significance of reverse leakage current differences between the substitutes?

A: The PG302R_R2_00001 exhibits lower reverse leakage current (1 µA) compared to both the original FR303GP-TP and FR303G (5 µA @ 200 V). Lower leakage current reduces power dissipation in reverse-biased conditions and is beneficial in applications with stringent power efficiency requirements or high-impedance circuits.

Q: Can these diodes be used interchangeably in existing PCB designs?

A: Yes. All three parts share identical DO-201AD axial through-hole package dimensions and mounting specifications. They can be used interchangeably in existing PCB designs without modification to board layout or assembly procedures.
