Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB152 is determined by matching the following critical electrical and mechanical parameters:

• Voltage Rating: Peak reverse voltage must equal or exceed 200 V
• Current Rating: Average rectified current must equal or exceed 15 A
• Forward Voltage Drop: Maximum forward voltage at rated current must not exceed 1.1 V @ 7.5 A
• Reverse Leakage: Leakage current characteristics at rated voltage
• Diode Configuration: Single-phase bridge rectifier topology
• Mounting Interface: QC terminal compatibility
• Temperature Range: Operating range of -55°C to 150°C

The GBPC1502 from onsemi meets all specified electrical parameters and maintains mechanical compatibility through identical QC terminal mounting and 4-square package configuration.

Parameter Comparison

Engineering Selection Recommendations

The GBPC1502 is a direct functional equivalent to the MB152. Both components are ROHS3 compliant and share identical electrical ratings for voltage, current, and temperature operation. The GBPC1502 exhibits superior reverse leakage characteristics (5 µA versus 10 µA), representing an improvement in performance. The GBPC1502 carries a product status of "Not For New Designs," indicating it is suitable for replacement and maintenance applications but not recommended for new product development.

Selection of the GBPC1502 as a substitute is supported by:

• Matching peak reverse voltage and average rectified current specifications
• Identical forward voltage drop characteristics
• Compatible QC terminal mounting interface
• Equivalent operating temperature range
• ROHS3 compliance alignment
• Availability of inventory stock

Frequently Asked Questions (FAQ)

Q: Can the GBPC1502 be used as a direct replacement for the MB152?

A: Yes. The GBPC1502 meets all electrical specifications of the MB152, including voltage rating (200 V), current rating (15 A), forward voltage drop (1.1 V @ 7.5 A), and operating temperature range (-55°C to 150°C). Both components use QC terminal mounting and 4-square package configurations.

Q: What is the difference in reverse leakage between these parts?

A: The MB152 specifies a maximum reverse leakage of 10 µA @ 200 V, while the GBPC1502 specifies 5 µA @ 200 V. The GBPC1502 exhibits lower leakage current, which may provide improved performance in applications sensitive to leakage characteristics.

Q: Are there any compliance differences between the MB152 and GBPC1502?

A: Both components are ROHS3 compliant and share the same HTSUS classification (8541.10.0080). The GBPC1502 is classified as REACH Unaffected, while the MB152 is REACH Affected. Both carry EAR99 ECCN classification.

Q: What is the significance of the "Not For New Designs" status of the GBPC1502?

A: This status indicates the GBPC1502 is suitable for replacement, repair, and legacy system applications but is not recommended for incorporation into new product designs. For new designs, consultation with the manufacturer regarding current-generation alternatives is advised.

Q: Are the package designations MB and GBPC interchangeable?

A: Both designations refer to 4-square bridge rectifier packages with QC terminal mounting. The different designations reflect manufacturer-specific nomenclature but represent mechanically and electrically compatible packages for this application.
