KBPC1510-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC1510-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 15 A average rectified current. This component is in active product status and widely used in power supply and industrial rectification applications. Substitute parts may be required due to inventory constraints, lead time considerations, or application-specific current capacity needs while maintaining voltage and thermal specifications.

Substitute Part Grouping Explanation

The GBPC3510-BP qualifies as a substitute for the KBPC1510-G based on the following substitution criteria:

Matching Parameters:

• Voltage - Peak Reverse (Max): 1 kV (identical)
• Diode Type: Single Phase (identical)
• Technology: Standard (identical)
• Operating Temperature Range: -55°C ~ 150°C (TJ) (identical)
• Mounting Type: QC Terminal (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Allowable Variance:

• Current - Average Rectified (Io): 35 A (exceeds 15 A requirement; higher current capacity is acceptable for downward compatibility)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 17.5 A (equivalent forward voltage characteristic at proportionally higher current)
• Current - Reverse Leakage @ Vr: 5 µA @ 1000 V (lower leakage is acceptable; measured at higher voltage)

Parameter Comparison

Engineering Selection Recommendations

Both the KBPC1510-G and GBPC3510-BP are active products with ROHS3 compliance and identical regulatory status (REACH Unaffected, ECCN EAR99). The GBPC3510-BP provides higher current capacity (35 A versus 15 A) while maintaining the same peak reverse voltage rating and operating temperature range. Selection between these parts should be based on circuit current requirements and PCB layout compatibility with the respective package designations (KBPC versus GBPC 4-Square formats).

Frequently Asked Questions (FAQ)

Q: Can GBPC3510-BP replace KBPC1510-G in all applications? A: The GBPC3510-BP is electrically compatible for applications requiring up to 15 A average rectified current. The higher current rating (35 A) does not create incompatibility for lower-current designs. Physical package compatibility must be verified, as KBPC and GBPC 4-Square packages may have dimensional differences.

Q: What is the significance of the current rating difference? A: The GBPC3510-BP's 35 A rating indicates higher thermal capacity and lower junction temperature rise at equivalent current levels. For circuits designed for 15 A operation, this provides thermal margin but does not alter electrical performance at the design current.

Q: Are the forward voltage characteristics equivalent? A: Both parts specify 1.1 V maximum forward voltage at their respective rated currents (7.5 A for KBPC1510-G, 17.5 A for GBPC3510-BP). Forward voltage characteristics are equivalent for the KBPC1510-G's operating range.

Q: Do package differences affect substitution? A: Both parts use QC Terminal mounting on 4-Square packages. However, KBPC and GBPC designations may indicate dimensional variations. Physical verification against PCB footprint requirements is necessary before substitution.

Q: Are compliance certifications identical? A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Regulatory status is equivalent for both components.
