Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2KBP02M-E4/51 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal 200 V
• Diode Type: Must be Single Phase
• Technology: Must be Standard
• Mounting Type: Must be Through Hole
• Current - Average Rectified (Io): Must meet or exceed 2 A
• Voltage - Forward (Vf) (Max): Must not exceed 1.1 V
• Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ 200 V
• RoHS Status: Must be ROHS3 Compliant

The substitute parts listed below satisfy these electrical and mechanical requirements and are classified as active products, providing long-term availability for production use.

Parameter Comparison

Engineering Selection Recommendations

KBP202G (SMC Diode Solutions) is the primary substitute for the 2KBP02M-E4/51. This part matches the original specification exactly at 2 A average rectified current, maintains identical voltage ratings and forward voltage characteristics, and is actively manufactured. The KBP202G is ROHS3 compliant and carries REACH Affected status, requiring compliance verification in regulated applications.

KBP02G (Diodes Incorporated) is a secondary substitute option. While it meets all voltage and leakage specifications and is ROHS3 compliant with REACH Unaffected status, its 1.5 A current rating is below the original 2 A specification. This part is suitable only for applications where the actual load current does not exceed 1.5 A.

Both substitutes are active products with established supply chains, providing superior long-term availability compared to the obsolete 2KBP02M-E4/51.

Frequently Asked Questions (FAQ)

Q: Can KBP02G replace the 2KBP02M-E4/51 in all applications?

A: KBP02G is electrically compatible for voltage and leakage specifications but is rated for 1.5 A average rectified current versus the original 2 A rating. Substitution is valid only if the application's actual rectified current requirement does not exceed 1.5 A.

Q: What is the difference between KBP202G and KBP02G?

A: The primary difference is current rating: KBP202G is rated for 2 A (matching the original part), while KBP02G is rated for 1.5 A. Both maintain identical voltage specifications and forward voltage characteristics. KBP202G is the direct equivalent.

Q: Are there package compatibility concerns?

A: The 2KBP02M-E4/51 uses a 4-SIP KBPM package. KBP02G uses a 4-SIP KBP package, and KBP202G uses a 4-ESIP package. All three are through-hole mounted with compatible pinouts for bridge rectifier applications. Physical board layout verification is recommended prior to assembly.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: KBP202G carries REACH Affected status, requiring compliance documentation for use in European Union markets and regulated supply chains. KBP02G is REACH Unaffected, simplifying regulatory compliance in these jurisdictions. Both parts are ROHS3 compliant.

Q: Can these parts be used interchangeably in existing designs?

A: KBP202G is a direct replacement for the 2KBP02M-E4/51 with no design modifications required. KBP02G requires load current verification to confirm operation within its 1.5 A rating. Package footprint compatibility should be confirmed for both substitutes.
