Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP303G C2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 3 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 3 A
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: KBP form factor

The KBP302G manufactured by SMC Diode Solutions meets all mandatory electrical and mechanical parameters required for direct substitution. Both components share identical voltage ratings, current capacity, forward voltage characteristics, and thermal operating range. The through-hole mounting configuration and KBP package form factor ensure mechanical compatibility in existing circuit board layouts.

Parameter Comparison

Engineering Selection Recommendations

The KBP302G is the direct functional equivalent for applications currently utilizing the obsolete KBP303G C2. The substitute part maintains all critical electrical specifications including 200 V peak reverse voltage, 3 A average rectified current, and 1.1 V forward voltage drop at rated current. Both components operate across the identical temperature range of -55°C to 150°C junction temperature.

The KBP302G is manufactured by SMC Diode Solutions and carries active product status, ensuring continued availability and supply chain reliability. Both the main part and substitute are ROHS3 compliant and carry identical ECCN and HTSUS classifications, supporting regulatory and compliance requirements.

The KBP302G exhibits lower reverse leakage current (5 µA versus 10 µA at 200 V), representing improved leakage characteristics that are beneficial in rectification applications. Both components feature unlimited moisture sensitivity level (MSL 1), indicating no moisture-related handling restrictions during storage and assembly.

Through-hole mounting configuration is maintained in the substitute part, enabling direct installation in existing printed circuit board designs without layout modifications. The KBP package form factor is preserved across both components.
