Engineering Selection Recommendations

FR302G (Taiwan Semiconductor Corporation): This part is a parametric equivalent with Active product status. All critical electrical parameters match the FR302GP-TP. The reverse leakage current specification is identical at 5 µA @ 100 V. Junction capacitance is lower at 30 pF, which may provide marginal benefits in high-frequency switching applications. This part is suitable for direct substitution in applications where the original FR302GP-TP is specified.

PG301R_R2_00001 (Panjit International Inc.): This part is a parametric equivalent with Active product status and Tape & Reel packaging matching the original FR302GP-TP. All critical electrical parameters are met. The reverse leakage current is superior at 1 µA @ 100 V, indicating lower off-state current. Junction capacitance is slightly higher at 60 pF. This part is suitable for direct substitution and offers improved leakage characteristics.

Both substitute parts carry ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the original component. Selection between FR302G and PG301R_R2_00001 depends on packaging requirements and leakage current specifications for the target application.

Frequently Asked Questions (FAQ)

Q: Can FR302G be used as a direct replacement for FR302GP-TP?

A: Yes. FR302G meets all critical electrical specifications: 100 V reverse voltage, 3 A average rectified current, 1.3 V forward voltage at 3 A, and 150 ns reverse recovery time. The DO-201AD axial through-hole package is identical. FR302G is an Active product, addressing the end-of-life status of FR302GP-TP.

Q: What is the difference between FR302G and PG301R_R2_00001?

A: Both parts are parametric equivalents with identical core electrical ratings. The primary differences are: (1) PG301R_R2_00001 has lower reverse leakage current at 1 µA versus 5 µA for FR302G; (2) PG301R_R2_00001 is supplied in Tape & Reel packaging, matching the original FR302GP-TP; (3) FR302G packaging information is not specified. For applications sensitive to leakage current or requiring reel packaging, PG301R_R2_00001 is preferred.

Q: Are there any temperature or compliance concerns with these substitutes?

A: No. Both substitute parts operate across the identical temperature range of -55°C to 150°C junction temperature. Both are ROHS3 Compliant and REACH Unaffected, matching the regulatory status of FR302GP-TP.

Q: Does the difference in junction capacitance affect circuit performance?

A: Junction capacitance differences (30 pF for FR302G, 50 pF for FR302GP-TP, 60 pF for PG301R_R2_00001) are minor and typically insignificant in general-purpose rectification circuits. In high-frequency switching applications, FR302G with lower capacitance may provide marginal performance benefits, but all three parts are functionally equivalent for standard rectifier applications.

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

A: Yes. All three parts use the DO-201AD axial through-hole package with identical pin configuration and mechanical dimensions. No PCB layout modifications are required for substitution.

Q: Which substitute part should be selected for new inventory procurement?

A: Both FR302G and PG301R_R2_00001 are Active products suitable for procurement. PG301R_R2_00001 is recommended if Tape & Reel packaging is required for automated assembly. FR302G is suitable if packaging format is flexible. Both offer superior availability compared to the end-of-life FR302GP-TP.
