KBP102G C2 Equivalent & Substitute Parts

Part Overview

The KBP102G C2 is a single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation, rated for 100 V peak reverse voltage and 1 A average rectified current. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing design support and procurement continuity. Bridge rectifiers in the KBP package category serve as full-wave rectification solutions in power supply applications, converting AC voltage to DC voltage through a four-diode configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP102G C2 is determined by the following critical parameters that must remain equal or superior in the replacement component:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 100 V (minimum requirement)
• 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 equal or be lower than 1 V @ 1 A
• Current - Reverse Leakage @ Vr: Substitute must equal or be lower than 10 µA @ 100 V
• Operating Temperature Range: Substitute must encompass or exceed the -55°C ~ 150°C range

The KBP01G from Diodes Incorporated satisfies all mandatory matching parameters and provides superior electrical characteristics in current capacity and reverse leakage performance, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The KBP01G manufactured by Diodes Incorporated is a qualified substitute for the obsolete KBP102G C2. Both components maintain identical package geometry (4-SIP, KBP) and through-hole mounting configuration, ensuring direct mechanical compatibility in existing PCB layouts without design modification.

The KBP01G demonstrates superior electrical performance across multiple parameters: increased current capacity (1.5 A versus 1 A), reduced reverse leakage current (5 µA versus 10 µA), and extended low-temperature operating range (-65°C versus -55°C). These characteristics provide enhanced reliability margins in rectification applications.

Both components maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. The active product status of the KBP01G provides assured long-term availability and supply chain continuity compared to the obsolete KBP102G C2.

Frequently Asked Questions (FAQ)

Q: Can the KBP01G directly replace the KBP102G C2 without PCB modifications?

A: Yes. Both components utilize identical 4-SIP, KBP package geometry and through-hole mounting configuration. Direct pin-for-pin substitution is possible without PCB layout changes.

Q: What are the key electrical differences between these components?

A: The KBP01G provides higher current capacity (1.5 A versus 1 A), lower reverse leakage (5 µA versus 10 µA), and extended low-temperature operation (-65°C versus -55°C). Forward voltage characteristics remain comparable at rated current levels.

Q: Are there compliance or certification concerns with substitution?

A: No. Both components maintain ROHS3 compliance and identical moisture sensitivity classification (MSL 1). Regulatory and environmental compliance requirements are equivalent.

Q: Why is the KBP102G C2 classified as obsolete?

A: Product obsolescence reflects discontinuation of manufacturing by Taiwan Semiconductor Corporation. The KBP01G from Diodes Incorporated represents the active equivalent in the market.

Q: Does the higher current rating of the KBP01G affect circuit operation?

A: No. The KBP01G is rated for 1.5 A average rectified current, which exceeds the 1 A requirement of the original design. The component operates within design specifications when used in circuits rated for 1 A operation.

Q: Are there packaging format differences between these parts?

A: The KBP102G C2 is supplied in standard packaging, while the KBP01G is supplied in tube packaging. Both maintain identical component dimensions and electrical characteristics. Packaging format does not affect electrical performance or mechanical compatibility.
