Substitute Part Grouping Explanation

Substitute components for the KBP203G are identified based on electrical and mechanical parameter equivalence. The following criteria determine substitution validity:

Electrical Parameters (Must Match):

• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
• Current - Reverse Leakage @ Vr: 10 µA @ 200 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Mechanical Parameters (Must Match):

• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-SIP, KBP

The KBP202G-G manufactured by Comchip Technology meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The KBP202G-G from Comchip Technology is electrically and mechanically equivalent to the KBP203G. The substitute component maintains identical electrical performance across all specified parameters and uses the same through-hole 4-SIP KBP package.
