KBP103G C2G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP103G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 200 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 category serve as full-wave rectification solutions in power supply applications requiring standardized through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP103G C2G is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 200 V
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBP

Allowable Parameter Variations:

• Current - Average Rectified (Io): Substitute must equal or exceed 1 A
• Voltage - Forward (Vf): Substitute must not exceed specified forward voltage at rated current
• Current - Reverse Leakage: Lower values are acceptable
• Operating Temperature Range: Substitute must encompass or exceed the original range
• RoHS and REACH Compliance: Substitute must maintain equivalent compliance status

The KBP02G from Diodes Incorporated satisfies all mandatory matching criteria and provides enhanced electrical performance within allowable parameter variations.

Parameter Comparison

Engineering Selection Recommendations

The KBP02G manufactured by Diodes Incorporated is a direct functional substitute for the obsolete KBP103G C2G. Selection of the KBP02G is supported by the following factors:

Compliance and Certification: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for applications subject to environmental standards.

Product Availability: The KBP02G holds active product status with 2240 units in stock, providing procurement continuity compared to the obsolete KBP103G C2G.

Electrical Performance: The KBP02G delivers enhanced electrical characteristics within the same voltage class. The 1.5 A current rating exceeds the 1 A requirement, and the reduced reverse leakage current (5 µA versus 10 µA) indicates improved device quality. The forward voltage specification of 1.1 V at 1.5 A represents an acceptable variation for standard bridge rectifier applications.

Thermal Performance: The extended operating temperature range of -65°C to 150°C provides superior thermal coverage compared to the original -55°C to 150°C specification.

Package Compatibility: Both components utilize identical 4-SIP KBP through-hole packaging, enabling direct mechanical and electrical substitution without circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can the KBP02G directly replace the KBP103G C2G in existing circuit boards?

A: Yes. Both components share identical 4-SIP KBP through-hole package geometry and pinout configuration. No circuit board modifications are required for mechanical or electrical substitution.

Q: What is the significance of the higher current rating on the KBP02G?

A: The KBP02G is rated for 1.5 A average rectified current compared to 1 A on the KBP103G C2G. This higher rating provides design margin and allows the substitute to operate at lower thermal stress in applications requiring the original 1 A specification.

Q: Are there compliance differences between the two parts?

A: No. Both the KBP103G C2G and KBP02G maintain ROHS3 compliance and REACH unaffected status. Regulatory requirements for environmental standards are equivalent.

Q: Why is the KBP02G forward voltage specification higher?

A: The KBP02G forward voltage of 1.1 V at 1.5 A is measured at a higher current level than the KBP103G C2G specification of 1 V at 1 A. This represents normal variation in bridge rectifier device characteristics and remains within acceptable limits for standard rectification applications.

Q: What is the advantage of the lower reverse leakage current in the KBP02G?

A: The KBP02G reverse leakage current of 5 µA at 200 V is half that of the KBP103G C2G at 10 µA. Lower reverse leakage indicates improved device quality and reduced standby current consumption in applications with extended idle periods.

Q: Is the extended temperature range of the KBP02G beneficial?

A: The KBP02G operating range of -65°C to 150°C extends the lower temperature limit by 10°C compared to the KBP103G C2G range of -55°C to 150°C. This provides enhanced performance in applications subject to extreme cold environments or thermal cycling.

Q: What is the product status difference, and why does it matter?

A: The KBP103G C2G is classified as obsolete, indicating discontinued manufacturing and limited future availability. The KBP02G maintains active product status with ongoing production and established supply chains, ensuring long-term procurement reliability.
