Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB1010-BP is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): Must equal or exceed 1 kV
• Current - Average Rectified (Io): Must equal or exceed 10 A
• Voltage - Forward (Vf): Must not exceed 1.1 V @ rated current
• Current - Reverse Leakage: Must not exceed 10 µA @ rated voltage
• Operating Temperature Range: Must encompass -55°C ~ 125°C

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (required)
• Package / Case: BR-6 4-Square configuration (required)
• Diode Type: Single Phase (required)
• Technology: Standard (required)

The MB88-BP does not meet the electrical requirements for direct substitution. Its peak reverse voltage rating of 800 V falls below the 1 kV requirement of the MB1010-BP, and its average rectified current rating of 8 A is insufficient for applications requiring 10 A capacity.

Parameter Comparison

Engineering Selection Recommendations

The MB88-BP cannot serve as a direct substitute for the MB1010-BP due to insufficient electrical ratings. The 800 V peak reverse voltage and 8 A average rectified current of the MB88-BP do not meet the 1 kV and 10 A specifications of the MB1010-BP.

For applications currently using the MB1010-BP, component selection must prioritize parts meeting or exceeding the specified 1 kV voltage and 10 A current ratings while maintaining the BR-6 Through Hole package configuration. The obsolete status of the MB1010-BP necessitates identification of active production alternatives with equivalent or superior electrical performance.

Both the MB1010-BP and MB88-BP maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), supporting environmental and reliability requirements across standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the MB88-BP replace the MB1010-BP in existing designs?

A: No. The MB88-BP has a maximum peak reverse voltage of 800 V and average rectified current of 8 A, both below the MB1010-BP specifications of 1 kV and 10 A. Using an undersized component creates risk of voltage breakdown and thermal stress.

Q: What are the critical parameters for finding a suitable substitute?

A: The substitute must meet or exceed: 1 kV peak reverse voltage, 10 A average rectified current, BR-6 Through Hole package, and -55°C ~ 125°C operating temperature range. Forward voltage and reverse leakage characteristics must not degrade circuit performance.

Q: Are the packages physically compatible?

A: Both parts use the BR-6 4-Square Through Hole package, ensuring mechanical compatibility. However, electrical rating differences prevent functional substitution.

Q: What compliance certifications are maintained?

A: Both parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity), supporting standard industrial and commercial applications without additional environmental controls.

Q: Why is the MB1010-BP listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active alternatives with equivalent or superior specifications should be identified for new procurement and long-term design support.
