MB88 Bridge Rectifier Single Phase 800V 8A - Equivalent & Substitute Parts

Part Overview

The MB88 is a single-phase bridge rectifier rated for 800V peak reverse voltage with 8A average rectified current, housed in a BR-6 through-hole package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The MB88-BP serves as a direct functional equivalent with identical electrical specifications and improved compliance status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB88 with the MB88-BP is based on strict electrical and mechanical parameter matching:

Qualifying Parameters for Substitution:

• Diode Type: Single Phase (identical)
• Technology: Standard (identical)
• Voltage - Peak Reverse (Max): 800 V (identical)
• Current - Average Rectified (Io): 8 A (identical)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 4 A (identical)
• Current - Reverse Leakage @ Vr: 10 µA @ 800 V (identical)
• Operating Temperature Range: -55°C ~ 125°C (TJ) (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: 4-Square, BR-6 (identical)

The MB88-BP maintains complete electrical and mechanical compatibility with the MB88, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The MB88-BP is the appropriate selection for new designs and ongoing production requiring active component status and regulatory compliance. The MB88-BP maintains identical electrical performance while offering ROHS3 compliance, addressing regulatory requirements for modern manufacturing environments. The MB88 remains available for legacy system maintenance where existing stock is present, though long-term availability is limited due to obsolete status.

Frequently Asked Questions (FAQ)

Q: Can MB88-BP directly replace MB88 in existing circuits? A: Yes. The MB88-BP provides identical electrical specifications across all critical parameters: 800V peak reverse voltage, 8A average rectified current, 1.1V forward voltage drop, and -55°C to 125°C operating range. The BR-6 through-hole package ensures mechanical compatibility.

Q: What is the primary difference between MB88 and MB88-BP? A: The MB88-BP is an active product with ROHS3 compliance, while the MB88 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences? A: No. Both parts use the 4-Square, BR-6 through-hole package with identical pinout and mechanical dimensions.

Q: Which part should be specified for new designs? A: The MB88-BP should be specified for new designs due to active product status and regulatory compliance certification.

Q: Is the MB88 still available for purchase? A: The MB88 remains in stock (1142 pcs) but is classified as obsolete. Availability is limited and will not be replenished.
