Substitute Part Grouping Explanation

Substitution eligibility for the KBPC3502T is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Current Rating Consideration: The KBPC3502T operates at 35 A average rectified current. Substitute parts are grouped by current capacity.

Engineering Selection Recommendations

Direct Equivalent (35 A Rating): The KBPC3502-G from Comchip Technology provides direct electrical and mechanical equivalence to the KBPC3502T. Both components share identical voltage ratings (200 V), current capacity (35 A), forward voltage characteristics (1.1 V @ 17.5 A), and operating temperature range (-55°C to 150°C). The KBPC3502-G maintains ROHS3 compliance and active product status. Selection of this substitute is appropriate for applications requiring identical performance specifications.

Higher Current Capacity Alternative (50 A Rating): The GBPC5002-G provides increased current handling capacity at 50 A while maintaining the same 200 V voltage rating and operating temperature range. This component is suitable for applications where current margin or future design scaling is required. The GBPC5002-G operates with identical forward voltage characteristics and maintains ROHS3 compliance and active product status.

Lower Current Capacity Alternatives: The KBPC2502-G (25 A) and KBPC1002-G (10 A) are available as substitutes for applications with reduced current requirements. These components maintain all voltage and temperature specifications of the primary part. Selection of lower-rated components is appropriate only when application current demands do not exceed the specified ratings.

Compliance Considerations: All substitute parts maintain active product status and RoHS compliance (ROHS3 standard). The KBPC3502-G and GBPC5002-G include REACH Unaffected designation, providing additional regulatory assurance for European market applications.

Frequently Asked Questions (FAQ)

Q: Can the KBPC3502-G replace the KBPC3502T in all applications?

A: The KBPC3502-G provides electrical and mechanical equivalence across all specified parameters: 200 V peak reverse voltage, 35 A average rectified current, 1.1 V forward voltage at 17.5 A, and -55°C to 150°C operating temperature. Both components use QC terminal mounting with 4-square package configuration. Direct substitution is valid for applications operating within these specifications.

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

A: Both KBPC and GBPC packages utilize 4-square configuration with QC terminal mounting. The primary distinction is manufacturer designation: KBPC is the GeneSiC and Comchip standard package identifier, while GBPC is the Comchip alternative designation. Mechanical and electrical compatibility is maintained across both package types for the specified voltage and current ratings.

Q: Can the GBPC5002-G be used in place of the KBPC3502T?

A: The GBPC5002-G is electrically compatible with the KBPC3502T for all voltage, temperature, and mounting specifications. The GBPC5002-G provides higher current capacity (50 A versus 35 A). This component is suitable for applications where the KBPC3502T operates, with the additional benefit of increased current margin. No derating or performance degradation occurs when substituting the higher-rated component.

Q: Are lower-rated alternatives (KBPC2502-G, KBPC1002-G) suitable substitutes?

A: The KBPC2502-G (25 A) and KBPC1002-G (10 A) maintain voltage, temperature, and mounting compatibility with the KBPC3502T. These components are suitable only for applications where the circuit current demand does not exceed their respective ratings. Use of an undersized component in an application designed for 35 A operation results in component overstress and failure.

Q: What is the significance of reverse leakage current differences?

A: The KBPC3502T specifies 5 µA reverse leakage at 200 V, while substitute parts specify 10 µA. Both values remain within acceptable limits for standard bridge rectifier applications. The difference reflects manufacturing process variations between GeneSiC and Comchip technologies. For applications with strict leakage specifications, the KBPC3502T maintains lower leakage performance.

Q: Do all substitute parts maintain the same RoHS compliance level?

A: The KBPC3502T holds RoHS Compliant certification. All substitute parts (KBPC3502-G, GBPC5002-G, KBPC2502-G, KBPC1002-G) maintain ROHS3 Compliant status, which represents an updated compliance standard. ROHS3 compliance encompasses RoHS requirements and provides equivalent environmental protection for component selection.

Q: What inventory considerations apply to substitute selection?

A: Current inventory levels are: KBPC3502T (1023 pcs), KBPC3502-G (1164 pcs), GBPC5002-G (876 pcs), KBPC2502-G (1193 pcs), KBPC1002-G (1356 pcs). Inventory availability should be evaluated against project timeline and volume requirements. All parts maintain active product status, ensuring continued availability for future procurement.
