Substitute Part Grouping Explanation

Substitution of the KBP154G C2 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Peak reverse voltage must equal 400 V
• Current Rating: Average rectified current must equal 1.5 A
• Diode Configuration: Single-phase bridge rectifier topology
• Package Type: 4-SIP KBP through-hole form factor
• Technology Class: Standard bridge rectifier technology
• Compliance: ROHS3 compliance and EAR99 ECCN classification

The KBP04G from Diodes Incorporated meets all substitution criteria. Both components share identical voltage and current specifications, package configuration, and regulatory compliance status. The substitute part maintains full electrical and mechanical compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The KBP04G represents a direct functional replacement for the obsolete KBP154G C2. Selection of the substitute part is supported by the following factors:

Product Status: The KBP04G maintains active production status with Diodes Incorporated, ensuring long-term availability and supply chain continuity. The original KBP154G C2 is classified as obsolete, making the substitute necessary for new procurement.

Electrical Equivalence: Both components deliver identical voltage and current specifications (400 V peak reverse, 1.5 A average rectified current) with matching forward voltage characteristics (1.1 V @ 1.5 A). The KBP04G exhibits lower reverse leakage current (5 µA versus 10 µA), representing an improvement in performance characteristics.

Thermal Performance: The KBP04G supports an extended operating temperature range (-65°C to 150°C) compared to the original part (-55°C to 150°C), providing enhanced thermal margin in demanding applications.

Regulatory Compliance: Both components maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, ensuring compatibility with current procurement and export regulations.

Package Compatibility: The 4-SIP KBP through-hole package is identical between both components, enabling direct board-level substitution without PCB redesign or mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can the KBP04G be used as a direct replacement for the KBP154G C2 in existing designs?

A: Yes. The KBP04G is electrically and mechanically equivalent to the KBP154G C2. Both components share identical voltage ratings (400 V), current ratings (1.5 A), forward voltage characteristics (1.1 V @ 1.5 A), and package configuration (4-SIP KBP through-hole). Direct substitution is supported without circuit modification.

Q: What are the key differences between these two bridge rectifiers?

A: The primary differences are manufacturer (Taiwan Semiconductor Corporation versus Diodes Incorporated) and product status (obsolete versus active). The KBP04G offers superior reverse leakage characteristics (5 µA versus 10 µA @ 400 V) and an extended lower operating temperature limit (-65°C versus -55°C). These differences represent improvements in the substitute part.

Q: Are there any compliance or certification differences between the KBP154G C2 and KBP04G?

A: No. Both components maintain identical compliance status: ROHS3 compliant, REACH unaffected, and EAR99 ECCN classification. Regulatory requirements are fully satisfied by either component.

Q: What is the packaging difference between these parts?

A: Both components use identical 4-SIP KBP through-hole packaging. The KBP154G C2 was supplied in standard packaging, while the KBP04G is supplied in tube packaging. This difference does not affect electrical performance or board-level installation.

Q: Why is the KBP154G C2 classified as obsolete?

A: Obsolescence reflects the manufacturer's discontinuation of this product line. The KBP04G from Diodes Incorporated remains in active production and serves the same functional requirements, making it the appropriate replacement for ongoing applications.

Q: Can the KBP04G handle the same voltage and current levels as the original part?

A: Yes. Both components are rated for 400 V peak reverse voltage and 1.5 A average rectified current. The KBP04G is fully capable of handling the electrical requirements of any application designed for the KBP154G C2.

Q: Is there any performance advantage to using the KBP04G over the original part?

A: The KBP04G exhibits lower reverse leakage current (5 µA versus 10 µA @ 400 V) and supports a wider operating temperature range (-65°C to 150°C versus -55°C to 150°C). These characteristics represent performance improvements in the substitute component.
