KBPC1506-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBPC1506-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 600 V 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 rating requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the KBPC1506-G are qualified based on the following criteria:

Mandatory Compatibility Parameters:

Voltage - Peak Reverse (Max): 600 V (must match exactly)
Diode Type: Single Phase (must match exactly)
Technology: Standard (must match exactly)
Mounting Type: QC Terminal (must match exactly)
Operating Temperature Range: -55°C ~ 150°C (TJ) (must match exactly)
Package / Case: 4-Square configuration (must match exactly)

Allowable Variation:

Current - Average Rectified (Io): May exceed the original 15 A rating
Voltage - Forward (Vf): May be equal or lower
Current - Reverse Leakage: May be equal or lower

The substitute parts GBPC2506-BP and GBPC3506-BP maintain all mandatory electrical and mechanical parameters while offering higher current ratings (25 A and 35 A respectively), making them suitable for applications requiring equal or greater current capacity.

Engineering Selection Recommendations

All three parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between KBPC1506-G and its substitutes depends on application current requirements:

KBPC1506-G: Select for applications requiring exactly 15 A average rectified current or lower.
GBPC2506-BP: Select for applications requiring 15 A to 25 A average rectified current capacity.
GBPC3506-BP: Select for applications requiring 25 A to 35 A average rectified current capacity.

All parts share identical voltage ratings, temperature operating range, and QC Terminal mounting configuration. The 4-Square package footprint is compatible across all three part numbers. Lower reverse leakage current in GBPC variants (5 µA versus 10 µA) represents an improvement in electrical performance.

Frequently Asked Questions (FAQ)

Q: Can GBPC2506-BP or GBPC3506-BP be used as direct replacements for KBPC1506-G?

A: Yes, both GBPC variants are electrically and mechanically compatible substitutes. They maintain the same 600 V peak reverse voltage, operating temperature range, and QC Terminal mounting. The higher current ratings (25 A and 35 A) do not prevent operation in circuits designed for 15 A, provided the circuit topology and thermal management remain unchanged.

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

A: Both use identical 4-Square package configurations with QC Terminal mounting. The designation prefix reflects the manufacturer (KBPC for Comchip Technology, GBPC for Micro Commercial Co). Physical dimensions and terminal compatibility are equivalent.

Q: Are there any compliance or certification differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 1 (Unlimited). Regulatory and environmental compliance is equivalent across all substitutes.

Q: Why do GBPC variants show lower reverse leakage current?

A: The GBPC2506-BP and GBPC3506-BP exhibit 5 µA reverse leakage at 600 V compared to 10 µA for KBPC1506-G. This represents improved electrical characteristics and does not affect substitution compatibility.

Q: Can a lower-rated part substitute for KBPC1506-G?

A: No. Substitute parts must maintain equal or higher current ratings. Using a part rated below 15 A average rectified current is not permitted.
