Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP105G C2G is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain the same peak reverse voltage specification of 600 V to ensure circuit protection and component reliability.

Package Compatibility: The substitute must use the 4-SIP KBP through-hole package to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Diode Type and Technology: The substitute must be a single-phase standard technology bridge rectifier to maintain functional equivalence in full-wave rectification applications.

Current Rating: The substitute may exceed the original 1 A current rating, provided it does not reduce the voltage or temperature specifications below the original design requirements.

Compliance Standards: The substitute must maintain ROHS3 compliance and REACH unaffected status to satisfy regulatory requirements.

The KBP06G from Diodes Incorporated meets all substitution criteria while offering enhanced electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The KBP06G from Diodes Incorporated is a direct substitute for the obsolete KBP105G C2G. The substitute part maintains identical voltage and package specifications while providing superior electrical characteristics. The KBP06G offers increased current capacity (1.5 A versus 1 A), lower reverse leakage current (5 µA versus 10 µA), and an extended lower operating temperature limit (-65°C versus -55°C). The substitute part carries active product status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Can the KBP06G directly replace the KBP105G C2G in existing applications?

A: Yes. Both components share identical voltage ratings (600 V), package configurations (4-SIP KBP through-hole), and diode type (single-phase standard technology). The KBP06G provides equivalent or superior performance across all specified parameters.

Q: What is the significance of the higher current rating on the KBP06G?

A: The KBP06G is rated for 1.5 A average rectified current compared to the KBP105G C2G at 1 A. This higher rating provides additional design margin and thermal headroom in applications operating at or near the original component's current limits. Circuits designed for 1 A operation will function within the KBP06G's specifications.

Q: Are there any thermal considerations when substituting these components?

A: The KBP06G extends the lower operating temperature limit to -65°C compared to the KBP105G C2G at -55°C. Both components maintain the same upper temperature limit of 150°C. The KBP06G's lower reverse leakage current (5 µA versus 10 µA) results in reduced thermal dissipation, providing a thermal advantage in high-temperature environments.

Q: Do both components require the same PCB footprint?

A: Yes. Both the KBP105G C2G and KBP06G use the 4-SIP KBP package configuration, ensuring identical through-hole pin spacing and PCB layout compatibility. No PCB modifications are required for substitution.

Q: What is the compliance status of the substitute part?

A: The KBP06G maintains ROHS3 compliance and REACH unaffected status, matching the regulatory requirements of the original KBP105G C2G. Both components satisfy environmental and hazardous substance restrictions applicable to electronic components.

Q: Why is the original KBP105G C2G classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. The KBP06G from Diodes Incorporated provides functional equivalence with active product status, ensuring continued availability and manufacturer support for new and legacy applications.
