Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBPC1504T is determined by the following criteria:

Voltage Compatibility: Peak reverse voltage must equal 400 V to maintain circuit protection and component reliability.

Current Rating: The average rectified current (Io) defines the thermal and electrical load capacity. Substitutes with lower current ratings (10 A) operate within reduced load conditions. Substitutes with higher current ratings (25 A) provide increased capacity margin.

Forward Voltage Characteristics: Forward voltage drop (Vf) at specified current levels affects power dissipation and circuit efficiency. Values of 1.1 V at proportional current levels maintain consistent thermal performance.

Reverse Leakage Current: Leakage specifications at rated voltage ensure minimal standby current and circuit isolation integrity.

Thermal Operating Range: The -55°C to 150°C junction temperature range must be maintained across all substitute candidates.

Mechanical Packaging: QC Terminal mounting and 4-Square KBPC package configuration ensure physical and electrical compatibility with existing circuit board layouts and connector systems.

Diode Type and Technology: Single-phase standard technology classification must remain consistent.

Parameter Comparison

Engineering Selection Recommendations

KBPC1004-G (Comchip Technology): This substitute operates at 10 A average rectified current, representing a 33% reduction from the KBPC1504T specification. Selection is appropriate for applications where circuit load requirements do not exceed 10 A continuous operation. The component maintains identical peak reverse voltage (400 V), matching thermal operating range (-55°C to 150°C), and compatible QC Terminal packaging. ROHS3 compliance status exceeds the RoHS Compliant requirement of the primary part. Reverse leakage current increases to 10 µA, which remains acceptable for standard rectification applications.

KBPC2504-G (Comchip Technology): This substitute operates at 25 A average rectified current, representing a 67% increase from the KBPC1504T specification. Selection is appropriate for applications requiring higher current capacity or where thermal margin enhancement is necessary. The component maintains identical peak reverse voltage (400 V), matching thermal operating range (-55°C to 150°C), and compatible QC Terminal packaging. ROHS3 compliance status exceeds the RoHS Compliant requirement of the primary part. Reverse leakage current increases to 10 µA, which remains acceptable for standard rectification applications.

Both substitute parts maintain Active product status and meet all mandatory electrical and mechanical compatibility criteria established for the KBPC1504T.

Frequently Asked Questions (FAQ)

Q: Can KBPC1004-G replace KBPC1504T in all applications?

A: KBPC1004-G is suitable only for applications where the circuit load does not exceed 10 A average rectified current. The 400 V peak reverse voltage rating, thermal range, and package configuration are compatible. Applications requiring 15 A or higher current capacity require the KBPC1504T or KBPC2504-G.

Q: What is the difference between KBPC1504T and KBPC2504-G current ratings?

A: KBPC1504T provides 15 A average rectified current capacity. KBPC2504-G provides 25 A capacity. The higher rating in KBPC2504-G allows operation at increased load levels and provides additional thermal margin in existing 15 A applications.

Q: Are the package configurations identical across all three parts?

A: KBPC1504T uses 4-Square KBPC-T packaging. KBPC1004-G and KBPC2504-G use 4-Square KBPC packaging. Both configurations are mechanically compatible with QC Terminal mounting systems, though minor dimensional variations may exist. Verification against specific PCB layout requirements is necessary.

Q: How do reverse leakage currents compare?

A: KBPC1504T specifies 5 µA reverse leakage at 400 V. Both KBPC1004-G and KBPC2504-G specify 10 µA at 400 V. The increased leakage in substitute parts remains within acceptable limits for standard single-phase rectification applications.

Q: What compliance certifications apply to these parts?

A: KBPC1504T holds RoHS Compliant certification. KBPC1004-G and KBPC2504-G hold ROHS3 Compliant certification, which represents an enhanced compliance standard. All three parts carry MSL 1 (Unlimited) moisture sensitivity classification and EAR99 export control designation.

Q: Can forward voltage characteristics affect circuit performance?

A: Forward voltage (Vf) is specified at 1.1 V maximum across all three parts at their respective current levels (7.5 A, 5 A, and 12.5 A). Forward voltage drop directly affects power dissipation and heat generation. Circuits designed for the KBPC1504T forward voltage characteristic will experience proportionally lower power dissipation with KBPC1004-G and proportionally similar dissipation with KBPC2504-G at equivalent load percentages.
