KBPC1502T Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC1502T is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 200 V peak reverse voltage and 15 A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers in this category are essential for AC-to-DC power conversion applications requiring standardized electrical and mechanical interfaces. Substitute parts become necessary when the original manufacturer part is unavailable, when inventory constraints exist, or when application requirements permit operation within alternative current ratings while maintaining voltage and thermal specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBPC1502T is determined by strict adherence to the following electrical and mechanical parameters:

Fixed Parameters (Non-Negotiable for Substitution):

• Voltage - Peak Reverse (Max): 200 V
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: QC Terminal
• Package / Case: 4-Square configuration
• Operating Temperature Range: -55°C to 150°C (TJ)

Variable Parameters (Permitted to Differ):

• Current - Average Rectified (Io): Substitute parts may have equal or higher current ratings
• Voltage - Forward (Vf) (Max) @ If: Substitute parts must not exceed 1.1 V at their respective test currents
• Current - Reverse Leakage @ Vr: Substitute parts may have equal or higher leakage current values

All substitute parts listed maintain identical voltage specifications, thermal operating range, and mechanical interface compatibility with the KBPC1502T. Current rating variations reflect different silicon die configurations within the same package family, permitting direct mechanical and electrical substitution for applications operating at or below the original 15 A specification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (Equal or Higher Current Capacity):

The KBPC2502-G, KBPC3502-G, and GBPC5002-G are suitable direct substitutes for the KBPC1502T in applications where the circuit design permits operation with higher current-rated components. These parts maintain identical voltage specifications, thermal operating range, and QC Terminal mounting compatibility. All substitute parts carry ROHS3 Compliant certification, meeting current environmental compliance requirements.

For Current-Limited Applications:

The KBPC1002-G is suitable only for applications where the circuit load does not exceed 10 A average rectified current. This part maintains all voltage, thermal, and mechanical specifications of the KBPC1502T but operates at a lower current threshold.

Compliance Considerations:

All listed substitute parts are Active product status with ROHS3 Compliant certification. The KBPC2502-G, KBPC3502-G, and GBPC5002-G carry REACH Unaffected status, indicating full regulatory alignment with current international standards.

Inventory Availability:

Current stock levels for substitute parts are: KBPC1002-G (1356 pcs), KBPC2502-G (1193 pcs), KBPC3502-G (1164 pcs), and GBPC5002-G (876 pcs), all classified as New Original In Stock.

Frequently Asked Questions (FAQ)

Q: Can KBPC1002-G replace KBPC1502T in all applications?

A: No. The KBPC1002-G has a maximum average rectified current rating of 10 A, compared to the KBPC1502T's 15 A rating. It is suitable only for applications where circuit load does not exceed 10 A. Exceeding this current rating will result in component failure.

Q: What is the difference between KBPC and GBPC package designations?

A: Both KBPC and GBPC are 4-Square QC Terminal packages with identical mechanical and electrical interfaces. The designation reflects different manufacturer product lines (KBPC from GeneSiC/Comchip, GBPC from Comchip). They are mechanically and electrically interchangeable within the specified voltage and current parameters.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original KBPC1502T is RoHS Compliant. All listed substitute parts (KBPC1002-G, KBPC2502-G, KBPC3502-G, GBPC5002-G) are ROHS3 Compliant, meeting or exceeding the original compliance standard.

Q: Can I use GBPC5002-G as a direct replacement for KBPC1502T?

A: Yes. The GBPC5002-G maintains identical voltage (200 V), thermal operating range (-55 to 150°C), and QC Terminal mounting specifications. The 50 A current rating exceeds the KBPC1502T's 15 A requirement, making it suitable for direct substitution in any application designed for the original part.

Q: What is the significance of the "-G" suffix in substitute part numbers?

A: The "-G" suffix indicates Comchip Technology manufacturer designation. All substitute parts listed carry this designation, distinguishing them from the original GeneSiC Semiconductor KBPC1502T. Electrical and mechanical specifications remain equivalent.

Q: Are there any thermal performance differences between the main part and substitutes?

A: All parts share identical operating temperature range (-55°C to 150°C TJ). Forward voltage drop (Vf) remains constant at 1.1 V maximum across all parts at their respective test currents, indicating equivalent thermal performance characteristics within the specified operating envelope.

Q: Can substitute parts with higher current ratings be used in lower-current applications?

A: Yes. Bridge rectifiers with higher current ratings operate within specification when used in lower-current applications. The component will not be stressed, and reliability is maintained. This approach is common in inventory standardization strategies.
