MB810-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB810-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 1 kV peak reverse voltage and 8 A average rectified current. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The BR-6 package configuration and through-hole mounting type are standard for this rectifier class.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB810-BP is determined by the following critical parameters:

• Diode Type & Technology: Single Phase, Standard technology
• Package / Case: 4-Square, BR-6 form factor (mechanical and electrical interface compatibility)
• Mounting Type: Through Hole (PCB assembly method)
• Current Rating: 8 A average rectified current (functional requirement)
• Voltage Rating: Peak reverse voltage must meet or exceed application requirements
• Compliance: RoHS3 and REACH status for regulatory alignment

The MB88-BP qualifies as a substitute based on matching diode type, technology, package, mounting type, and current rating. The voltage rating difference (800 V vs. 1 kV) determines application suitability.

Parameter Comparison

Engineering Selection Recommendations

The MB88-BP is an active substitute for the obsolete MB810-BP. Both components share identical mechanical packaging (BR-6), electrical interface characteristics, current rating (8 A), forward voltage drop (1.1 V @ 4 A), and thermal operating range (-55°C to 125°C). Both maintain ROHS3 compliance and REACH unaffected status.

The primary distinction is voltage rating: the MB810-BP is rated for 1 kV peak reverse voltage, while the MB88-BP is rated for 800 V. Selection between these parts depends on the application's peak reverse voltage requirement. If the circuit operates at or below 800 V peak reverse, the MB88-BP provides an active, in-stock alternative. If the circuit requires 1 kV capability, the MB88-BP is not suitable for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can the MB88-BP replace the MB810-BP in all applications?

A: No. The MB88-BP has a lower peak reverse voltage rating (800 V vs. 1 kV). It is suitable only for applications where the peak reverse voltage does not exceed 800 V. Applications requiring 1 kV or higher peak reverse voltage capability must use the MB810-BP or an equivalent 1 kV rated bridge rectifier.

Q: Are the BR-6 packages mechanically identical?

A: Yes. Both the MB810-BP and MB88-BP use the 4-Square, BR-6 package configuration. They are mechanically interchangeable in terms of PCB footprint and through-hole mounting.

Q: What is the significance of the product status difference?

A: The MB810-BP is classified as obsolete, indicating it is no longer in active production. The MB88-BP is active, meaning it is currently manufactured and available for procurement. For new designs or long-term supply assurance, the active MB88-BP is preferred when voltage requirements permit.

Q: Do both parts have the same thermal characteristics?

A: Yes. Both the MB810-BP and MB88-BP operate across the same temperature range (-55°C to 125°C junction temperature) and share identical forward voltage characteristics (1.1 V @ 4 A).

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements.
