Key Parameters

Substitute Part Grouping Explanation

Substitution of the KBP02M-M4/51 is determined by strict equivalence across the following critical parameters:

• Voltage - Peak Reverse (Max): 200 V minimum
• Current - Average Rectified (Io): 1.5 A minimum
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-SIP configuration
• RoHS Compliance: ROHS3 Compliant

The KBP02G from Diodes Incorporated meets all substitution criteria. Both parts share identical voltage and current ratings, operate within compatible temperature ranges, maintain through-hole mounting compatibility, and comply with the same environmental standards.

Parameter Comparison

Engineering Selection Recommendations

The KBP02G is a direct substitute for the obsolete KBP02M-M4/51. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The KBP02G maintains active product status with established supply availability (2240 pcs in stock), whereas the KBP02M-M4/51 is obsolete. The KBP02G provides an extended minimum operating temperature range (-65°C versus -55°C), offering improved performance in low-temperature applications. Forward voltage characteristics are within acceptable tolerance for standard bridge rectifier applications.

Frequently Asked Questions (FAQ)

Q: Can the KBP02G directly replace the KBP02M-M4/51 in existing designs?

A: Yes. Both components share identical voltage and current ratings (200 V, 1.5 A), equivalent reverse leakage characteristics, and compatible through-hole 4-SIP package configurations. The KBP02G meets all electrical and mechanical requirements for direct substitution.

Q: What is the difference in forward voltage between these parts?

A: The KBP02M-M4/51 specifies 1 V maximum forward voltage at 1 A, while the KBP02G specifies 1.1 V maximum at 1.5 A. This 0.1 V difference is within acceptable tolerance for standard rectifier applications and does not affect circuit functionality.

Q: Are there temperature range differences?

A: The KBP02G operates from -65°C to 150°C, compared to the KBP02M-M4/51 range of -55°C to 150°C. The KBP02G provides 10°C additional low-temperature capability, making it suitable for applications requiring extended cold-temperature performance.

Q: Do both parts comply with current environmental standards?

A: Yes. Both the KBP02M-M4/51 and KBP02G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: What is the package compatibility between KBPM and KBP designations?

A: Both designations refer to 4-SIP through-hole package configurations with identical pin spacing and mounting characteristics. The parts are mechanically and electrically interchangeable in PCB layouts designed for standard 4-SIP bridge rectifier packages.
