Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP151G C2 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBP

The KBP005G manufactured by Diodes Incorporated meets all critical electrical specifications and maintains identical mechanical packaging. Both components operate within compatible temperature ranges and maintain ROHS3 compliance. The substitute part is currently in active production status, providing supply continuity for the obsolete KBP151G C2.

Parameter Comparison

Engineering Selection Recommendations

The KBP005G is a direct functional equivalent for the obsolete KBP151G C2. Both components share identical electrical ratings for voltage, current, and forward voltage characteristics. The KBP005G offers additional advantages: active production status ensures long-term availability, extended operating temperature range (-65°C minimum versus -55°C), and lower reverse leakage current (5 µA versus 10 µA). Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

For applications currently using the KBP151G C2, direct substitution with the KBP005G requires no circuit modifications. The identical 4-SIP KBP package and through-hole mounting configuration ensure mechanical compatibility with existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the KBP005G replace the KBP151G C2 in existing designs?

A: Yes. The KBP005G is electrically and mechanically equivalent. Both components have identical voltage ratings (50 V), current ratings (1.5 A), forward voltage characteristics (1.1 V @ 1.5 A), and package configurations (4-SIP KBP through-hole). No circuit modifications are required.

Q: What are the differences between these two parts?

A: The KBP005G has lower reverse leakage current (5 µA versus 10 µA) and an extended operating temperature minimum (-65°C versus -55°C). The KBP005G is in active production, while the KBP151G C2 is obsolete. These differences represent improvements in the substitute part.

Q: Are both parts RoHS compliant?

A: Yes. Both the KBP151G C2 and KBP005G are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial applications.

Q: Does packaging differ between these parts?

A: No. Both components use identical 4-SIP KBP through-hole packaging. PCB layouts and mounting procedures remain unchanged when substituting the KBP005G for the KBP151G C2.

Q: Why is the KBP151G C2 listed as obsolete?

A: The KBP151G C2 has been discontinued by Taiwan Semiconductor Corporation. The KBP005G from Diodes Incorporated provides equivalent functionality with active production support.

Q: What is the moisture sensitivity level for these components?

A: Both components have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
