Key Parameters

Substitute Part Grouping Explanation

Substitution of the MUR480GP-TP is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 800 V
• Current - Average Rectified (Io): 4 A
• Voltage - Forward (Vf) (Max) @ If: 1.85 V @ 4 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: DO-201AD or compatible axial configuration

Acceptable Variation Parameters:

• Reverse Recovery Time (trr): Equivalent or faster performance
• Current - Reverse Leakage @ Vr: Equal or lower leakage at rated voltage
• Operating Temperature - Junction: Equal or wider temperature range
• Product Status: Active status preferred for new procurement

The substitute parts identified below meet all critical matching parameters and maintain electrical performance within the specified operating envelope.

Parameter Comparison

Engineering Selection Recommendations

MUR480ERLG (onsemi): This part is the primary substitute for the MUR480GP-TP. It maintains identical electrical ratings across voltage, current, and forward voltage specifications. The MUR480ERLG carries Active product status, ensuring long-term availability and supply chain stability. The extended operating temperature range (-65 to 175 °C) provides additional thermal margin compared to the main part. The reverse recovery time of 100 ns is within acceptable fast-recovery classification. This part is suitable for direct replacement in new procurement activities and design revisions.

UF408G_AY_00001 (Panjit International Inc.): This part is a parametric equivalent offering identical electrical performance to the MUR480GP-TP. The UF408G_AY_00001 maintains the same voltage, current, and forward voltage ratings with matching reverse recovery time of 75 ns. It carries Active product status and ROHS3 compliance. The DO-201AD package configuration ensures mechanical compatibility. This part serves as an alternative source for procurement and is suitable for applications requiring the exact electrical characteristics of the original design.

Both substitute parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for the MUR480GP-TP application space.

Frequently Asked Questions (FAQ)

Q: Can the MUR480ERLG be used as a direct replacement for the MUR480GP-TP?

A: Yes. The MUR480ERLG meets all critical electrical parameters: 800 V reverse voltage, 4 A average rectified current, and 1.85 V forward voltage at 4 A. Both parts are through-hole axial diodes with fast-recovery characteristics. The MUR480ERLG has Active product status, making it the recommended substitute for ongoing designs.

Q: What is the difference between the MUR480ERLG and UF408G_AY_00001?

A: Both parts are electrically equivalent to the MUR480GP-TP with identical voltage and current ratings. The MUR480ERLG is manufactured by onsemi and features an extended operating temperature range (-65 to 175 °C). The UF408G_AY_00001 is manufactured by Panjit International Inc. and maintains the original operating temperature range (-55 to 150 °C). Selection between these parts depends on supplier availability, procurement lead times, and temperature margin requirements for the specific application.

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

A: The MUR480GP-TP uses a DO-201AD axial package. The UF408G_AY_00001 is supplied in DO-201AD, ensuring direct mechanical compatibility. The MUR480ERLG is supplied in DO-201AA and DO-27 axial packages, which are mechanically compatible with DO-201AD in through-hole applications. All three parts are axial through-hole diodes suitable for the same PCB footprint.

Q: What is the significance of the reverse recovery time difference between these parts?

A: The MUR480GP-TP and UF408G_AY_00001 both specify 75 ns reverse recovery time, while the MUR480ERLG specifies 100 ns. All three parts meet the fast-recovery classification (≤ 500ns, > 200mA). The 25 ns difference in the MUR480ERLG does not affect functional compatibility in standard rectification applications. Applications with stringent switching speed requirements should reference the specific circuit design parameters.

Q: Why is the MUR480GP-TP marked as "Not For New Designs"?

A: This designation indicates the part has been superseded by the manufacturer and is no longer recommended for new product development. The MUR480ERLG and UF408G_AY_00001 are both Active products with equivalent or superior specifications, making them appropriate choices for new designs and ongoing production.

Q: Are all three parts RoHS compliant?

A: Yes. The MUR480GP-TP, MUR480ERLG, and UF408G_AY_00001 are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronic component use in regulated markets.
