Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP104G C2 is determined by the following critical parameters:

Voltage Rating Compatibility: The substitute part must maintain the 400 V peak reverse voltage specification to ensure circuit protection and operational safety.

Current Rating Compatibility: The substitute part must support a minimum average rectified current of 1 A. Parts with higher current ratings (1.5 A) are acceptable as they provide design margin without compromising circuit function.

Package Compatibility: The substitute must utilize the 4-SIP, KBP through-hole package to ensure mechanical and electrical compatibility with existing printed circuit board layouts.

Forward Voltage Characteristics: The substitute must maintain forward voltage specifications within acceptable operating ranges at rated current levels.

Reverse Leakage Current: The substitute must demonstrate reverse leakage current performance suitable for the application's voltage and temperature operating conditions.

Temperature Operating Range: The substitute must support the required operating temperature envelope or an extended range that encompasses the original specification.

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

Engineering Selection Recommendations

The KBP04G manufactured by Diodes Incorporated qualifies as a direct substitute for the obsolete KBP104G C2. The substitute part maintains identical voltage and package specifications while providing enhanced performance characteristics in current capacity, reverse leakage, and operating temperature range.

Product Status Consideration: The KBP04G holds active product status with 2264 units in stock, ensuring long-term availability and supply chain continuity compared to the obsolete KBP104G C2.

Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements without modification to procurement or documentation procedures.

Performance Enhancement: The KBP04G delivers superior reverse leakage current performance (5 µA versus 10 µA) and an extended low-temperature operating range (-65°C versus -55°C), providing additional design margin for demanding applications.

Current Rating: The 1.5 A average rectified current rating of the KBP04G exceeds the 1 A requirement of the original part, enabling operation with increased design margin without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the KBP04G directly replace the KBP104G C2 without PCB modifications?

A: Yes. Both parts utilize identical 4-SIP, KBP through-hole package geometry and pin configuration, enabling direct mechanical and electrical substitution without printed circuit board layout changes.

Q: What is the significance of the higher 1.5 A current rating on the KBP04G?

A: The increased current rating provides design margin and thermal headroom for the application. The substitute part operates within safe limits at the original 1 A design current while accommodating potential future load increases or thermal stress conditions.

Q: Does the KBP04G meet the same regulatory requirements as the KBP104G C2?

A: Yes. The KBP04G maintains ROHS3 compliance and REACH unaffected status identical to the original part, satisfying all regulatory and procurement compliance requirements.

Q: How does the reverse leakage current difference affect circuit performance?

A: The KBP04G demonstrates lower reverse leakage current (5 µA versus 10 µA) at 400 V, indicating superior diode quality and reduced parasitic current paths. This enhancement improves circuit efficiency and reduces heat generation in the rectifier stage.

Q: Is the extended temperature range of the KBP04G (-65°C to 150°C) necessary for standard applications?

A: The extended low-temperature capability (-65°C versus -55°C) provides additional operational margin for applications deployed in cold environments or subjected to thermal cycling stress. Standard applications operating within -55°C to 150°C experience no functional difference.

Q: What packaging format is supplied for the KBP04G?

A: The KBP04G is supplied in tube packaging, suitable for automated assembly processes and manual component handling. The original KBP104G C2 packaging format is not specified in the provided data.

Q: Are there any forward voltage considerations when substituting the KBP04G?

A: The forward voltage specifications are comparable between parts. The KBP04G exhibits 1.1 V at 1.5 A versus 1 V at 1 A for the original part. At the original 1 A operating point, the forward voltage difference is negligible and does not require circuit redesign.
