KBP105G C2 Equivalent & Substitute Parts

Part Overview

The KBP105G C2 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 600 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity. Bridge rectifiers in the KBP package series serve as full-wave rectification solutions in power supply applications requiring standardized through-hole mounting.

Substitute Part Grouping Explanation

Substitution of the KBP105G C2 is determined by electrical and mechanical compatibility within the following criteria:

Critical Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 600 V (minimum requirement)
• Package / Case: 4-SIP, KBP (mechanical compatibility)
• Mounting Type: Through Hole

Allowable Variation Parameters:

• Current - Average Rectified (Io): Equal to or greater than 1 A
• Voltage - Forward (Vf): Equal to or less than specified maximum
• Current - Reverse Leakage: Equal to or less than specified maximum
• Operating Temperature Range: Equal to or exceeding the original range
• RoHS and REACH Compliance: Maintained at equivalent or higher standards

The KBP06G qualifies as a direct substitute based on matching voltage rating, package type, mounting configuration, and compliance certifications, while providing enhanced current capacity and improved reverse leakage characteristics.

Engineering Selection Recommendations

The KBP06G manufactured by Diodes Incorporated is a qualified substitute for the obsolete KBP105G C2. Selection is supported by the following factors:

Compliance and Regulatory Status: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental and hazardous substance restrictions.

Product Availability: The KBP06G is classified as active product status with 10,481 pieces in stock, providing reliable procurement continuity compared to the obsolete KBP105G C2 with no ongoing production.

Electrical Performance: The KBP06G meets or exceeds all critical electrical parameters. The 600 V peak reverse voltage rating matches the original specification. The 1.5 A average rectified current rating provides 50% additional capacity margin over the 1 A requirement, supporting thermal headroom in applications. Reverse leakage current is reduced to 5 µA, indicating superior semiconductor quality.

Thermal Performance: The operating temperature range of -65°C to 150°C extends the lower temperature limit by 10°C, providing enhanced performance in cold-environment applications while maintaining the upper temperature limit.

Mechanical and Packaging Compatibility: Both components utilize identical 4-SIP KBP package configuration and through-hole mounting, ensuring direct board-level compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the KBP06G be used as a direct replacement for the KBP105G C2 in existing designs?

A: Yes. The KBP06G is mechanically and electrically compatible. Both components share identical package type (4-SIP, KBP), mounting method (through-hole), and voltage rating (600 V). The substitute provides equal or superior performance across all specified parameters.

Q: What are the key differences between these two bridge rectifiers?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Diodes Incorporated), product status (obsolete versus active), and current rating (1 A versus 1.5 A). The KBP06G also features lower reverse leakage current (5 µA versus 10 µA) and an extended lower operating temperature limit (-65°C versus -55°C).

Q: Does the higher current rating of the KBP06G affect circuit operation?

A: No. A higher current rating does not negatively affect circuit operation. The substitute is rated for 1.5 A average rectified current, which exceeds the 1 A requirement of the original design. This provides additional thermal margin and component reliability without altering circuit behavior.

Q: Are there any compliance or certification concerns with substitution?

A: No. Both components maintain identical RoHS3 compliance and REACH unaffected status. Regulatory and environmental certifications are equivalent, supporting use in applications with compliance requirements.

Q: What is the significance of the lower reverse leakage current in the KBP06G?

A: Lower reverse leakage current (5 µA versus 10 µA) indicates superior semiconductor material quality and manufacturing process control. This characteristic reduces parasitic current paths and improves overall circuit efficiency, particularly in high-impedance applications.

Q: Is the KBP package configuration identical between both components?

A: Yes. Both the KBP105G C2 and KBP06G utilize the 4-SIP KBP package with through-hole mounting. No board layout modifications or mechanical adjustments are required for substitution.

Q: What is the moisture sensitivity level for both components?

A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.
