Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UF5404GP-TP are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalents (Full Compatibility): Parts that match all critical electrical specifications including reverse voltage rating (400 V), average rectified current (3 A), forward voltage drop (1.3 V @ 3 A), reverse recovery time (50 ns), and package type (DO-201AD axial through-hole). These parts are direct functional replacements.

Parametric Substitutes (Enhanced Performance): Parts that exceed the minimum electrical requirements while maintaining the same package and mounting configuration. These include higher current ratings or improved reverse leakage characteristics, suitable for applications where performance headroom is beneficial.

The substitution logic is based on the following criteria:

• Reverse voltage rating must equal or exceed 400 V
• Average rectified current must equal or exceed 3 A
• Package type must be DO-201AD axial through-hole
• Mounting type must be through-hole
• RoHS3 compliance required
• Operating temperature range must support application requirements

Parameter Comparison

Engineering Selection Recommendations

HER305G A0G is a parametric equivalent offering identical electrical specifications to the UF5404GP-TP. This part maintains 400 V reverse voltage rating, 3 A average rectified current, 1.3 V forward voltage drop at 3 A, and 50 ns reverse recovery time. Inventory availability is 1779 pieces. RoHS3 compliance and operating temperature range (-55°C ~ 150°C) match the main part. This substitute is suitable for direct replacement in applications requiring no performance modification.

SF36G is a parametric equivalent with improved reverse leakage characteristics (5 µA versus 10 µA at 400 V) and faster reverse recovery time (35 ns versus 50 ns). Electrical ratings for reverse voltage, current, and forward voltage remain identical. Inventory availability is 1534 pieces. RoHS3 compliance and operating temperature range match the main part. This substitute provides enhanced performance margins in the same package.

EGP51G-E3/C is a parametric substitute with higher current rating (5 A versus 3 A) and lower forward voltage drop (1.25 V @ 5 A versus 1.3 V @ 3 A). Reverse voltage rating remains 400 V. This part is suitable for applications requiring higher current capacity or lower forward voltage losses. Inventory availability is 11390 pieces, the highest among all substitutes. RoHS3 compliance is confirmed. Operating temperature range extends to 175°C maximum junction temperature.

All substitute parts maintain Active product status and ROHS3 compliance. Selection should be based on application current requirements, thermal constraints, and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can HER305G A0G replace UF5404GP-TP in all applications?

A: Yes. HER305G A0G is a parametric equivalent with identical reverse voltage (400 V), average rectified current (3 A), forward voltage drop (1.3 V @ 3 A), and reverse recovery time (50 ns). Both use DO-201AD axial through-hole packaging. No circuit modifications are required.

Q: What is the difference between SF36G and UF5404GP-TP?

A: SF36G maintains identical voltage and current ratings but offers improved performance: reverse recovery time is 35 ns (faster than 50 ns) and reverse leakage current is 5 µA (lower than 10 µA at 400 V). Both parts use DO-201AD packaging. SF36G is a direct replacement with performance enhancement.

Q: When should EGP51G-E3/C be selected instead of the main part?

A: EGP51G-E3/C should be selected when the application requires higher current capacity (5 A versus 3 A) or lower forward voltage drop (1.25 V @ 5 A). The 400 V reverse voltage rating remains unchanged. This substitute is suitable for higher-power rectification circuits or applications with stringent voltage drop requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (HER305G A0G, SF36G, and EGP51G-E3/C) are ROHS3 compliant, matching the compliance status of UF5404GP-TP.

Q: Do substitute parts require PCB layout modifications?

A: No. All substitute parts use DO-201AD axial through-hole packaging with identical mechanical dimensions. PCB layouts and mounting procedures remain unchanged.

Q: What is the operating temperature range for each substitute?

A: UF5404GP-TP, HER305G A0G, and SF36G operate from -55°C to 150°C junction temperature. EGP51G-E3/C extends the upper limit to 175°C maximum junction temperature, providing additional thermal margin in high-temperature applications.

Q: Which substitute has the highest inventory availability?

A: EGP51G-E3/C has the highest inventory with 11390 pieces in stock, compared to 1779 pieces for HER305G A0G and 1534 pieces for SF36G.
