Key Parameters

Substitute Part Grouping Explanation

Substitution of the R9G20415ASOO is determined by equivalence in the following critical parameters:

• Voltage Rating: DC reverse voltage must equal or exceed 400 V
• Current Rating: Average rectified current must meet or exceed 1500 A
• Package Type: Mechanical form factor must be DO-200AB, B-PUK clamp-on configuration
• Technology Class: Standard recovery rectifier technology
• Forward Voltage Characteristics: Forward voltage drop must be compatible with circuit design specifications
• Reverse Leakage: Leakage current performance at rated voltage

The substitute part VS-SD1500C04L from Vishay General Semiconductor - Diodes Division satisfies all substitution criteria. This part maintains identical voltage and package specifications while providing enhanced current capacity (1600 A versus 1500 A) and improved reverse leakage performance (50 mA versus 75 mA at 400 V). The substitute is classified as active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The VS-SD1500C04L is a direct substitute for the obsolete R9G20415ASOO. Selection of the Vishay part is supported by the following factors:

• Electrical Compatibility: Identical 400 V reverse voltage rating and superior current capacity (1600 A versus 1500 A) ensures operation within or below design stress levels
• Mechanical Compatibility: Identical DO-200AB, B-PUK clamp-on package permits direct mounting without mechanical redesign
• Product Availability: Active product status with 1113 units in stock ensures procurement continuity
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status meet current environmental standards
• Performance Enhancement: Reduced reverse leakage current (50 mA versus 75 mA) provides improved thermal and reliability characteristics

The substitute part operates within all specified electrical parameters of the original design while offering enhanced performance margins and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the VS-SD1500C04L directly replace the R9G20415ASOO without circuit modification?

A: Yes. Both parts share identical voltage ratings (400 V), compatible current specifications (1600 A versus 1500 A), and identical DO-200AB, B-PUK package configurations. Direct mechanical and electrical substitution is supported.

Q: What is the significance of the higher current rating on the substitute part?

A: The VS-SD1500C04L is rated for 1600 A average rectified current compared to 1500 A on the original part. This provides a 100 A margin above the design requirement, reducing component stress and extending operational life.

Q: How do the forward voltage characteristics compare?

A: The R9G20415ASOO specifies 1.65 V maximum forward voltage at 1500 A. The VS-SD1500C04L specifies 1.64 V maximum at 3000 A. At the design operating point of 1500 A, the substitute part exhibits equivalent or superior forward voltage performance.

Q: What is the difference in reverse leakage current?

A: The R9G20415ASOO exhibits 75 mA reverse leakage at 400 V. The VS-SD1500C04L exhibits 50 mA reverse leakage at 400 V. The 25 mA reduction in leakage current reduces thermal dissipation and improves reliability margins.

Q: Are there any compliance or regulatory differences?

A: The VS-SD1500C04L carries ROHS3 compliance certification, whereas the R9G20415ASOO does not specify RoHS status. Both parts are REACH unaffected and carry identical ECCN and HTSUS classifications.

Q: Is the DO-200AB, B-PUK package identical on both parts?

A: Yes. Both parts use the DO-200AB, B-PUK clamp-on package configuration. Mechanical mounting, thermal interface, and electrical connection methods are identical.

Q: Why is the original part classified as obsolete?

A: The R9G20415ASOO is listed as obsolete by the manufacturer. The VS-SD1500C04L from Vishay is classified as active product, ensuring long-term availability and continued manufacturing support.
