KBP107G C2G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP107G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 1 kV peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, indicating that direct procurement from the original manufacturer may be limited or unavailable. Bridge rectifiers in this voltage and current class are used in AC-to-DC conversion applications requiring standard rectification performance. Identifying equivalent substitute parts ensures design continuity and maintains supply chain reliability for applications utilizing this component specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of bridge rectifier components is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): Must equal or exceed the original specification (1 kV minimum)
• Diode Type: Must be Single Phase to maintain circuit topology
• Technology: Must be Standard classification
• Mounting Type: Must be Through Hole for PCB compatibility
• Package / Case: Must be 4-SIP, KBP form factor for mechanical fit

Performance Considerations:

• Current - Average Rectified (Io): Substitute may exceed original rating; lower ratings are not acceptable
• Voltage - Forward (Vf): Substitute specifications must be compatible with circuit design margins
• Current - Reverse Leakage: Lower leakage values indicate improved performance
• Operating Temperature Range: Substitute range must encompass or exceed the original range

Compliance Requirements:

• RoHS Status: Must maintain ROHS3 Compliant status
• Moisture Sensitivity Level: Must be rated at MSL 1 or equivalent
• REACH Status: Must maintain REACH Unaffected classification

The KBP10G from Diodes Incorporated meets all electrical, mechanical, and compliance criteria for substitution with the KBP107G C2G.

Parameter Comparison

Engineering Selection Recommendations

The KBP10G manufactured by Diodes Incorporated is a direct substitute for the obsolete KBP107G C2G. Selection of the KBP10G is supported by the following factors:

Product Availability: The KBP107G C2G is classified as obsolete, with limited inventory availability. The KBP10G is an active product with substantial inventory (11,733 pcs), ensuring reliable procurement for current and future production requirements.

Electrical Equivalence: Both components share identical peak reverse voltage (1 kV) and single-phase bridge rectifier topology. The KBP10G is rated for 1.5 A average rectified current, exceeding the original 1 A specification, providing design margin for applications operating at or near the original current rating.

Compliance Certification: Both components maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards.

Thermal Performance: The KBP10G operating temperature range (-65°C ~ 150°C) extends below the original specification (-55°C ~ 150°C), providing enhanced performance in low-temperature environments.

Mechanical Compatibility: Identical 4-SIP, KBP package and through-hole mounting type ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the KBP10G be used as a direct replacement for the KBP107G C2G without circuit modifications?

A: Yes. Both components share identical peak reverse voltage (1 kV), single-phase bridge rectifier topology, and 4-SIP KBP package configuration. The KBP10G is rated for higher average rectified current (1.5 A vs. 1 A), making it suitable for applications designed for the original 1 A specification.

Q: What is the significance of the higher current rating on the KBP10G?

A: The KBP10G is rated for 1.5 A average rectified current compared to the original 1 A rating. This higher rating provides design margin and does not create compatibility issues in applications operating at or below the original 1 A specification. The component will operate within its rated parameters in such applications.

Q: Are there differences in forward voltage between the two components?

A: The KBP107G C2G specifies a maximum forward voltage of 1 V at 1 A, while the KBP10G specifies 1.1 V at 1.5 A. This 0.1 V difference at higher current is within typical design tolerances for bridge rectifier applications and does not preclude substitution.

Q: How do the reverse leakage characteristics compare?

A: The KBP10G exhibits lower reverse leakage current (5 µA @ 1000 V) compared to the KBP107G C2G (10 µA @ 1000 V). Lower leakage current represents improved performance and does not create compatibility concerns.

Q: Is the operating temperature range of the KBP10G compatible with the original design?

A: Yes. The KBP10G operating temperature range (-65°C ~ 150°C) encompasses and exceeds the original specification (-55°C ~ 150°C). The substitute component is suitable for applications across the full original temperature range and extends performance capability to lower temperatures.

Q: Are both components RoHS compliant?

A: Yes. Both the KBP107G C2G and KBP10G are ROHS3 compliant and maintain REACH Unaffected status, ensuring compatibility with current environmental and regulatory requirements.

Q: What is the packaging difference between the two components?

A: Both components use identical 4-SIP, KBP through-hole packaging. The KBP107G C2G is supplied in standard packaging, while the KBP10G is supplied in tube packaging. This packaging difference does not affect electrical performance or PCB compatibility.

Q: Why is the KBP107G C2G classified as obsolete?

A: Product obsolescence typically results from manufacturer discontinuation decisions based on market demand, technology evolution, or product line consolidation. The KBP10G represents the active equivalent in the current product portfolio.
