2KBP10-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2KBP10-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 1 kV peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The through-hole KBPL package configuration and standard rectification technology establish the baseline for equivalent component selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2KBP10-BP is determined by strict equivalence across the following electrical and mechanical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Peak Reverse Voltage: 1 kV minimum rating
• Average Rectified Current: 2 A minimum rating
• Mounting Type: Through Hole
• Package Category: 4-SIP form factor (KBPL or GBP variants acceptable)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The KBP210G-BP qualifies as a direct substitute based on matching all critical electrical specifications and through-hole mounting requirements. Package variant differences (GBP vs. KBPL) do not affect functional equivalence within the 4-SIP family.

Parameter Comparison

Engineering Selection Recommendations

The KBP210G-BP is a qualified substitute for the 2KBP10-BP based on electrical parameter equivalence and regulatory compliance alignment. The substitute part maintains identical peak reverse voltage, average rectified current, and reverse leakage specifications. The forward voltage characteristic of the KBP210G-BP (1.1 V @ 2 A) is lower than the main part (1.2 V @ 2 A), resulting in reduced power dissipation and improved thermal performance in rectification applications.

The operating temperature range of the KBP210G-BP (-55°C ~ 150°C) is narrower than the main part (-55°C ~ 165°C) by 15°C at the upper limit. This difference must be evaluated against specific application thermal requirements.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification, ensuring compatibility with standard manufacturing and storage protocols. The KBP210G-BP is currently in active production status, providing superior long-term availability compared to the obsolete 2KBP10-BP.

Frequently Asked Questions (FAQ)

Q: Can the KBP210G-BP be used as a direct replacement for the 2KBP10-BP in existing designs?

A: Yes, the KBP210G-BP qualifies as a direct electrical substitute. Both parts share identical peak reverse voltage (1 kV), average rectified current (2 A), and reverse leakage specifications (10 µA @ 1000 V). The through-hole mounting type and 4-SIP package family ensure mechanical compatibility. Verify that the application's maximum operating temperature does not exceed 150°C (TJ) to account for the narrower temperature range of the substitute.

Q: What is the significance of the package variant difference (KBPL vs. GBP)?

A: Both KBPL and GBP are 4-SIP package variants used for single-phase bridge rectifiers. The functional performance and pin configuration remain identical. The package designation reflects manufacturing process or supplier differences but does not affect electrical characteristics or board-level compatibility.

Q: How does the lower forward voltage of the KBP210G-BP affect circuit performance?

A: The KBP210G-BP exhibits a forward voltage of 1.1 V @ 2 A compared to 1.2 V @ 2 A for the 2KBP10-BP. This 0.1 V reduction decreases power dissipation in the rectifier, resulting in lower heat generation and improved thermal efficiency. No circuit redesign is required; the lower forward voltage is a performance improvement.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain ROHS3 compliance and REACH Unaffected status. Moisture sensitivity classification is identical (MSL 1, Unlimited). No compliance barriers exist for substitution.

Q: What should be considered when selecting between the main part and substitute?

A: The 2KBP10-BP is obsolete and should not be selected for new designs. The KBP210G-BP is the recommended choice due to active production status, improved availability, and superior electrical characteristics. For legacy system maintenance, the KBP210G-BP provides equivalent functionality with enhanced performance and supply chain reliability.
