Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP104G C2G is determined by the following critical parameters that must remain compatible:

Voltage Rating: Peak reverse voltage must equal or exceed 400 V to maintain circuit protection and reliability.

Current Capacity: Average rectified current must meet or exceed the 1 A requirement of the original design.

Package Type: The 4-SIP KBP through-hole package ensures mechanical and electrical compatibility with existing PCB layouts and mounting infrastructure.

Forward Voltage Characteristics: Forward voltage drop at rated current must be within acceptable limits to prevent excessive heat dissipation and circuit performance degradation.

Reverse Leakage: Leakage current specifications ensure minimal standby current draw and circuit efficiency.

Operating Temperature Range: The component must function across the specified temperature envelope to maintain reliability in the target application environment.

Compliance Standards: RoHS3 compliance and REACH unaffected status ensure regulatory alignment and environmental safety.

The KBP04G from Diodes Incorporated meets all substitution criteria while offering enhanced specifications in current capacity and temperature range.

Frequently Asked Questions (FAQ)

Q: Can the KBP04G directly replace the KBP104G C2G without circuit modifications?

A: Yes. The KBP04G maintains identical voltage rating, package type, and mounting configuration. The enhanced current capacity and lower reverse leakage represent performance improvements that do not require circuit redesign.

Q: What is the significance of the 1.5 A current rating on the KBP04G versus the 1 A rating on the KBP104G C2G?

A: The KBP04G's higher current capacity provides design margin and thermal headroom. In applications requiring 1 A, the substitute operates at lower stress levels, extending component life and reducing thermal dissipation.

Q: Are there any temperature range limitations when substituting the KBP04G for the KBP104G C2G?

A: No. The KBP04G extends the low-temperature operating range to -65°C, providing broader environmental compatibility. The upper temperature limit remains 150°C, matching the original specification.

Q: Does the KBP04G packaging differ from the KBP104G C2G?

A: No. Both components use the 4-SIP KBP through-hole package. PCB footprints, lead spacing, and mounting procedures remain identical.

Q: What is the impact of the 0.1 V increase in forward voltage on the KBP04G?

A: The forward voltage increase from 1 V to 1.1 V at higher current (1.5 A versus 1 A) is within normal tolerance variation for bridge rectifier technology. In 1 A applications, the actual forward voltage drop will be lower than the specified maximum.

Q: Are both components RoHS compliant?

A: Yes. Both the KBP104G C2G and KBP04G are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial applications.

Q: Why is the KBP104G C2G classified as obsolete?

A: Obsolescence reflects discontinuation by the original manufacturer. The KBP04G from Diodes Incorporated provides equivalent functionality with active production status, ensuring ongoing availability for new designs and replacement applications.
