Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP101G C2 is determined by strict alignment of electrical and mechanical parameters within the bridge rectifier category. The primary substitution criteria are:

Voltage Rating Compatibility: The substitute part must maintain the same peak reverse voltage specification of 50 V to ensure circuit protection and component reliability.

Current Rating Consideration: While the KBP101G C2 is rated for 1 A average rectified current, substitute parts with equal or higher current ratings (1.5 A or greater) are electrically compatible, as they provide equivalent or superior current handling capacity without circuit modification.

Forward Voltage Characteristics: Forward voltage drop must remain within acceptable limits for the application. Substitute parts with forward voltage specifications at or below the original specification ensure thermal performance equivalence.

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

Compliance and Environmental Specifications: Substitute parts must maintain ROHS3 compliance and MSL 1 rating to meet regulatory and manufacturing requirements.

The KBP005G from Diodes Incorporated meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The KBP005G from Diodes Incorporated is the direct substitute for the obsolete KBP101G C2. Selection of this substitute is based on the following engineering factors:

Product Status and Availability: The KBP005G maintains active product status with confirmed inventory of 2060 units in stock, ensuring reliable supply chain access compared to the obsolete KBP101G C2.

Electrical Compatibility: The KBP005G maintains identical peak reverse voltage (50 V) and package configuration (4-SIP KBP), with current rating increased to 1.5 A. This higher current rating provides design margin without requiring circuit modification.

Compliance Alignment: Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status, ensuring regulatory and manufacturing process compatibility.

Thermal Performance: The KBP005G extends the operating temperature range to -65°C ~ 150°C (TJ), providing enhanced thermal margin compared to the original -55°C ~ 150°C specification.

Reverse Leakage Improvement: The KBP005G exhibits lower reverse leakage current (5 µA @ 50 V) compared to the KBP101G C2 (10 µA @ 50 V), indicating improved device quality and reduced standby current characteristics.

Frequently Asked Questions (FAQ)

Q: Can the KBP005G directly replace the KBP101G C2 without PCB modification?

A: Yes. The KBP005G uses the identical 4-SIP KBP through-hole package and maintains the same pin configuration, allowing direct socket substitution without PCB layout changes.

Q: What is the significance of the higher 1.5 A current rating on the KBP005G compared to the 1 A rating of the KBP101G C2?

A: The higher current rating indicates the KBP005G can handle greater average rectified current. In applications where the KBP101G C2 was rated at 1 A, the KBP005G provides additional current capacity margin. No circuit modification is required, as the substitute part is backward compatible with lower current applications.

Q: Are there differences in forward voltage drop between these parts?

A: The KBP005G exhibits a forward voltage of 1.1 V @ 1.5 A compared to 1 V @ 1 A for the KBP101G C2. Forward voltage specifications are measured at different current levels; direct comparison at identical current levels would require manufacturer datasheets. For most power supply applications, this difference is negligible.

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

A: The KBP005G extends the lower operating temperature limit to -65°C compared to -55°C for the KBP101G C2. This provides enhanced performance in cold environment applications. The upper temperature limit remains 150°C for both parts.

Q: What is the difference in reverse leakage current between these parts?

A: The KBP005G exhibits 5 µA @ 50 V reverse leakage compared to 10 µA @ 50 V for the KBP101G C2. Lower reverse leakage indicates reduced standby current and improved device characteristics, beneficial for low-power or battery-powered applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the KBP101G C2 and KBP005G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What packaging format is used for the KBP005G?

A: The KBP005G is supplied in tube packaging, while the KBP101G C2 does not specify packaging format in the provided data. Both components use the 4-SIP KBP through-hole package configuration for circuit board mounting.
