KBP101G C2G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP101G C2G is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, designed for 50 V applications with 1 A average rectified current capacity. This component is classified as obsolete, making identification of equivalent and substitute parts necessary for ongoing design support, maintenance, and production continuity. Bridge rectifiers in the KBP package series serve as full-wave rectification solutions in power supply circuits and are commonly used in industrial and consumer electronics applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP101G C2G is determined by strict electrical and mechanical compatibility criteria. The following parameters must align for a part to function as a direct substitute:

Critical Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 50 V minimum
• Package / Case: 4-SIP, KBP form factor
• Mounting Type: Through Hole

Allowable Parameter Variations:

• Current - Average Rectified (Io): Equal to or greater than 1 A
• Voltage - Forward (Vf): Equal to or less than the original specification
• Current - Reverse Leakage: Equal to or less than the original specification
• Operating Temperature Range: Equal to or wider than the original range

The KBP005G from Diodes Incorporated meets all critical matching parameters and demonstrates improved electrical characteristics in current capacity, reverse leakage, and operating temperature range, qualifying it as a direct substitute for the obsolete KBP101G C2G.

Engineering Selection Recommendations

The KBP005G from Diodes Incorporated is the qualified substitute for the obsolete KBP101G C2G. Selection is based on the following engineering criteria:

Product Status Alignment: The KBP005G maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete KBP101G C2G.

Electrical Compatibility: The KBP005G meets or exceeds all critical electrical parameters. The increased current capacity (1.5 A versus 1 A) and improved reverse leakage characteristics (5 µA versus 10 µA) provide enhanced performance margins without introducing incompatibility.

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

Thermal Performance: The KBP005G extends the operating temperature range to -65°C ~ 150°C, providing broader thermal operating margins compared to the original -55°C ~ 150°C specification.

Package Compatibility: Identical 4-SIP, KBP through-hole packaging ensures direct mechanical and electrical interchangeability without PCB redesign or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the KBP005G directly replace the KBP101G C2G without circuit modifications?

A: Yes. The KBP005G is electrically and mechanically compatible with the KBP101G C2G. Both components share identical package geometry (4-SIP, KBP), mounting type (through hole), and peak reverse voltage rating (50 V). The substitute part meets or exceeds all electrical specifications of the original part.

Q: What is the significance of the higher current rating on the KBP005G?

A: The KBP005G is rated for 1.5 A average rectified current compared to 1 A on the KBP101G C2G. This higher rating provides additional design margin and allows the substitute part to handle applications requiring current levels between 1 A and 1.5 A without thermal stress or performance degradation.

Q: Are there compliance differences between the two parts?

A: No. Both the KBP101G C2G and KBP005G maintain ROHS3 compliance and REACH unaffected status. Regulatory and environmental compliance requirements are identical between the two parts.

Q: Why is the KBP101G C2G classified as obsolete?

A: The KBP101G C2G is listed as obsolete by the original manufacturer, Taiwan Semiconductor Corporation. This classification indicates the part is no longer in active production. The KBP005G from Diodes Incorporated is an active production alternative that fulfills the same functional requirements.

Q: Does the extended operating temperature range of the KBP005G affect compatibility?

A: No. The KBP005G extends the operating temperature range to -65°C ~ 150°C, which encompasses the original KBP101G C2G range of -55°C ~ 150°C. The wider temperature specification provides additional design flexibility without introducing incompatibility.

Q: What packaging format is used for the KBP005G?

A: The KBP005G is supplied in tube packaging. Both the main part and substitute use identical 4-SIP, KBP through-hole package geometry, ensuring direct PCB compatibility regardless of packaging format.

Q: Are there any electrical parameter differences that require circuit analysis?

A: The KBP005G exhibits slightly higher forward voltage (1.1 V @ 1.5 A versus 1 V @ 1 A) and lower reverse leakage (5 µA @ 50 V versus 10 µA @ 50 V). These differences are within normal manufacturing tolerances for bridge rectifier technology and do not require circuit redesign for standard power supply applications.
