KBP08M-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The KBP08M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 800 V peak reverse voltage with 1.5 A average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The through-hole KBPR package configuration and standard rectification technology establish the baseline for equivalent part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the KBP08M-BP is determined by the following critical parameters:

• Voltage - Peak Reverse (Max): Must equal or exceed 800 V
• Diode Type: Must be Single Phase
• Mounting Type: Must be Through Hole
• Technology: Must be Standard
• Operating Temperature Range: Must encompass -55°C ~ 150°C
• RoHS Status: Must maintain ROHS3 Compliance

The KBP208G-BP qualifies as a substitute based on matching all critical electrical and mechanical parameters. While the current rating increases from 1.5 A to 2 A, this represents a higher capacity within the same voltage and package class, maintaining full compatibility with the original design envelope.

Parameter Comparison

Engineering Selection Recommendations

The KBP208G-BP is the qualified substitute for the obsolete KBP08M-BP. Selection is based on:

• Electrical parameter equivalence across voltage, current, and leakage specifications
• Identical single-phase bridge rectifier topology and standard technology classification
• Maintained through-hole mounting configuration for PCB compatibility
• ROHS3 compliance preservation for regulatory continuity
• Active product status ensuring long-term availability and supply chain stability

The increased current rating (2 A vs. 1.5 A) provides design margin without introducing incompatibility, as the substitute operates within the same voltage class and thermal envelope.

Frequently Asked Questions (FAQ)

Q: Can the KBP208G-BP directly replace the KBP08M-BP in existing designs?

A: Yes. The KBP208G-BP maintains identical peak reverse voltage (800 V), forward voltage characteristics (1.1 V), reverse leakage (10 µA @ 800 V), and operating temperature range (-55°C ~ 150°C). The through-hole 4-SIP package configuration supports direct PCB mounting compatibility.

Q: What is the difference between the KBPR and GBP package designations?

A: Both are 4-SIP through-hole packages for single-phase bridge rectifiers. The KBPR designation applies to the KBP08M-BP, while GBP applies to the KBP208G-BP. Both packages are mechanically and electrically compatible for through-hole PCB assembly.

Q: Why is the current rating higher on the substitute part?

A: The KBP208G-BP is rated for 2 A average rectified current compared to the KBP08M-BP's 1.5 A. This represents a higher capacity variant within the same voltage class and does not create incompatibility. Designs operating at or below 1.5 A will function within the substitute's rated envelope.

Q: Are there compliance or certification differences between these parts?

A: Both parts maintain ROHS3 compliance. The KBP208G-BP includes REACH Unaffected status, providing additional regulatory documentation. Both carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: What is the product status significance?

A: The KBP08M-BP is obsolete, indicating discontinued manufacturing. The KBP208G-BP is active, ensuring ongoing availability, documented supply chain support, and manufacturer technical resources for the design lifecycle.
