MB86-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB86-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 600 V peak reverse voltage and 8 A average rectified current in a BR-6 through-hole package. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement planning. Equivalent parts must maintain identical current ratings, compatible voltage specifications, and matching mechanical form factors to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB86-BP are identified based on the following critical parameters that determine functional compatibility:

• Current Rating: Must equal 8 A average rectified current
• Package / Case: Must be 4-Square, BR-6 through-hole configuration
• Mounting Type: Must be Through Hole
• Diode Type & Technology: Must be Single Phase, Standard technology
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The MB88-BP qualifies as a substitute because it maintains identical current, package, mounting, and temperature specifications. The higher voltage rating (800 V vs. 600 V) represents an upward-compatible specification that does not compromise the original design requirements.

Parameter Comparison

Engineering Selection Recommendations

The MB88-BP is a direct substitute for the MB86-BP based on matching electrical and mechanical specifications. The primary distinction is product status: the MB86-BP is obsolete while the MB88-BP is active, ensuring continued availability and supply chain support. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, satisfying regulatory and environmental requirements.

The MB88-BP's higher peak reverse voltage rating (800 V) provides enhanced voltage margin relative to the original 600 V specification, making it suitable for applications where the MB86-BP was previously specified. No derating or design modification is required for direct substitution in existing circuits designed for the MB86-BP.

Frequently Asked Questions (FAQ)

Q: Can the MB88-BP replace the MB86-BP in existing designs?

A: Yes. The MB88-BP maintains identical current, forward voltage, temperature range, and package specifications. The higher voltage rating does not create incompatibility and provides additional voltage margin.

Q: Are the BR-6 packages physically identical?

A: Yes. Both the MB86-BP and MB88-BP use the 4-Square, BR-6 through-hole package, ensuring mechanical compatibility and direct board-level substitution without layout modifications.

Q: What is the significance of the obsolete status for the MB86-BP?

A: Obsolete status indicates the MB86-BP is no longer manufactured. The MB88-BP, with active status, provides a supported alternative for new procurement and long-term supply chain continuity.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the MB86-BP and MB88-BP are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, satisfying equivalent regulatory and environmental standards.

Q: Is there a performance difference between the 600 V and 800 V ratings?

A: The MB88-BP's higher voltage rating does not affect forward voltage drop, reverse leakage current, or thermal characteristics at equivalent operating points. The higher rating represents increased voltage withstand capability without performance degradation.
