Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UG56GHA0G is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 400 V
• Current - Average Rectified (Io): 5 A
• Package / Case: DO-201AD, Axial
• Mounting Type: Through Hole
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)

Compliance Requirements:

• RoHS Status: ROHS3 Compliant
• Product Status: Active

The substitute part EGP51G-E3/C meets all mandatory matching parameters and compliance requirements. Both parts are rated for identical voltage and current specifications, utilize the same DO-201AD axial through-hole package, and maintain Fast Recovery speed classification. Both components are ROHS3 compliant and carry Active product status, ensuring long-term availability and regulatory alignment.

Parameter Comparison

Engineering Selection Recommendations

Both the UG56GHA0G and EGP51G-E3/C are qualified for direct substitution based on electrical and mechanical parameter equivalence. Selection between these parts should be based on the following factors:

Inventory and Lead Time: The EGP51G-E3/C maintains higher inventory levels (11,390 pcs) compared to the UG56GHA0G (1,118 pcs), providing improved availability for high-volume applications.

Compliance and Qualification: Both parts maintain ROHS3 compliance and Active product status. The UG56GHA0G carries AEC-Q101 automotive qualification, while the EGP51G-E3/C is part of the SUPERECTIFIER® series. Selection should align with specific automotive or industrial qualification requirements of the end application.

Electrical Performance Characteristics: The EGP51G-E3/C exhibits lower forward voltage drop (1.25 V vs. 1.55 V @ 5 A) and lower reverse leakage current (5 µA vs. 10 µA @ 400 V), resulting in reduced power dissipation and improved efficiency. The UG56GHA0G provides faster reverse recovery time (20 ns vs. 50 ns), which may be advantageous in high-frequency switching applications.

Temperature Range: The EGP51G-E3/C supports an extended lower operating temperature limit (-65°C vs. -55°C), providing broader thermal operating envelope for cold-environment applications.

Frequently Asked Questions (FAQ)

Q: Can the EGP51G-E3/C directly replace the UG56GHA0G in existing designs?

A: Yes. Both parts are rated for 400 V DC reverse voltage, 5 A average rectified current, and utilize the DO-201AD axial through-hole package. Electrical and mechanical parameters are equivalent, permitting direct substitution without circuit redesign.

Q: What are the differences in forward voltage drop between these parts?

A: The UG56GHA0G exhibits a maximum forward voltage drop of 1.55 V at 5 A, while the EGP51G-E3/C is rated at 1.25 V at 5 A. The lower forward voltage of the substitute part results in reduced power dissipation and improved thermal performance in the application.

Q: Are both parts suitable for automotive applications?

A: The UG56GHA0G carries AEC-Q101 automotive qualification. The EGP51G-E3/C is manufactured by Vishay and maintains ROHS3 compliance and Active product status. Automotive application suitability should be verified against specific end-use qualification requirements.

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

A: The UG56GHA0G has a reverse recovery time of 20 ns, while the EGP51G-E3/C is rated at 50 ns. Faster reverse recovery reduces switching losses in high-frequency rectification circuits. Applications operating at frequencies where reverse recovery time is critical should evaluate this parameter against circuit requirements.

Q: Do both parts have identical package dimensions?

A: Yes. Both the UG56GHA0G and EGP51G-E3/C are packaged in DO-201AD axial through-hole format with identical mechanical specifications, permitting direct board-level substitution without layout modifications.

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

A: The UG56GHA0G operates from -55°C to 175°C junction temperature. The EGP51G-E3/C operates from -65°C to 175°C, providing an extended lower temperature capability for cold-environment applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UG56GHA0G and EGP51G-E3/C are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.
