2KBP06M-E4/51 Equivalent & Substitute Parts

Part Overview

The 2KBP06M-E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. Bridge rectifiers in this voltage and current class are fundamental in AC-to-DC conversion applications requiring through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2KBP06M-E4/51 is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 600 V
• Diode Type: Must be Single Phase
• Technology: Must be Standard
• Mounting Type: Must be Through Hole
• Package / Case: Must be compatible 4-SIP form factor
• Current - Average Rectified (Io): Must support minimum 2 A operation
• Voltage - Forward (Vf): Must not exceed 1.1 V at rated current
• Current - Reverse Leakage: Must not exceed 5 µA @ 600 V
• RoHS Compliance: Must maintain ROHS3 Compliant status

The KBP06G from Diodes Incorporated meets these substitution criteria with equivalent electrical performance within the specified parameter ranges.

Parameter Comparison

Engineering Selection Recommendations

The KBP06G is an active product from Diodes Incorporated and represents the primary substitute for the obsolete 2KBP06M-E4/51. Both components maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

The KBP06G operates within a lower maximum current rating of 1.5 A compared to the 2 A specification of the original part. Circuit designs must verify that the 1.5 A rating is sufficient for the intended application. The KBP06G provides an extended lower operating temperature limit of -65°C versus -55°C on the original part, while the upper temperature limit is 150°C compared to 165°C. Applications requiring the full -55°C to 165°C range must evaluate whether the KBP06G's -65°C to 150°C range is acceptable.

Both components share identical voltage ratings (600 V peak reverse), forward voltage characteristics (1.1 V max), and reverse leakage specifications (5 µA @ 600 V), confirming electrical equivalence within their respective current ratings.

Frequently Asked Questions (FAQ)

Q: Can the KBP06G directly replace the 2KBP06M-E4/51 in all applications?

A: The KBP06G is electrically equivalent for voltage and leakage characteristics but has a lower current rating of 1.5 A versus 2 A. Applications operating at or below 1.5 A average rectified current can use the KBP06G as a direct substitute. Applications requiring the full 2 A rating require alternative parts or circuit redesign.

Q: Are the package dimensions identical between KBPM and KBP?

A: Both use the 4-SIP through-hole form factor. The KBPM and KBP designations indicate manufacturer-specific package variants. Physical compatibility must be verified against PCB footprint specifications before substitution.

Q: What is the impact of the different operating temperature ranges?

A: The 2KBP06M-E4/51 operates from -55°C to 165°C, while the KBP06G operates from -65°C to 150°C. Applications requiring operation above 150°C cannot use the KBP06G. Applications requiring operation below -55°C benefit from the KBP06G's extended lower limit.

Q: Why is the 2KBP06M-E4/51 marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The KBP06G from Diodes Incorporated is an active product and represents the recommended path for new designs and ongoing procurement.

Q: Are both parts RoHS compliant?

A: Yes, both the 2KBP06M-E4/51 and KBP06G are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
