MB16M-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB16M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, designed for 60 V peak reverse voltage applications with 1 A average rectified current. This component utilizes Schottky diode technology and is packaged in a 4-DIP (0.200", 5.08mm) through-hole configuration. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB16M-BP is determined by the following critical parameters:

Functional Compatibility Criteria:

• Diode Type: Single Phase bridge rectifier configuration
• Mounting Type: Through Hole
• Package Category: 4-DIP form factor

Electrical Performance Boundaries:

• Voltage - Peak Reverse (Max): Must equal or exceed 60 V
• Current - Average Rectified (Io): Must equal or exceed 1 A
• Operating Temperature Range: Must encompass or extend the -55°C to 125°C specification

Regulatory & Environmental Compliance:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: Acceptable for through-hole applications

The DF04M from onsemi meets these substitution criteria as a single-phase bridge rectifier in through-hole 4-DIP packaging with electrical ratings that exceed the MB16M-BP requirements.

Parameter Comparison

Engineering Selection Recommendations

The DF04M serves as a functional substitute for the MB16M-BP based on the following engineering criteria:

Electrical Sufficiency: The DF04M provides peak reverse voltage rating of 400 V, which exceeds the 60 V requirement of the MB16M-BP. Average rectified current capacity of 1.5 A exceeds the 1 A specification. Both components maintain ROHS3 compliance and operate across overlapping temperature ranges, with the DF04M extending to 150°C.

Physical Compatibility Considerations: Both components utilize through-hole mounting and 4-DIP packaging. The DF04M package footprint (4-EDIP, 0.300", 7.62mm) differs from the MB16M-BP (4-DIP, 0.200", 5.08mm). PCB layout verification is required to confirm pin spacing compatibility with existing circuit board designs.

Technology Difference: The MB16M-BP employs Schottky diode technology, while the DF04M uses standard diode technology. This difference results in higher forward voltage (1.1 V vs. 700 mV) and higher reverse leakage current (5 µA vs. 500 nA) in the DF04M. System thermal and power dissipation analysis is necessary to confirm acceptability in the target application.

Obsolescence Status: Both components are classified as obsolete. Inventory availability should be confirmed prior to design implementation.

Frequently Asked Questions (FAQ)

Q: Can the DF04M directly replace the MB16M-BP without PCB modification?

A: Physical pin compatibility requires verification. While both components are 4-DIP through-hole packages, the MB16M-BP uses 0.200" (5.08mm) spacing and the DF04M uses 0.300" (7.62mm) spacing. PCB layout review is mandatory before substitution.

Q: What is the impact of the technology difference between Schottky and standard diodes?

A: The DF04M standard diode technology results in higher forward voltage drop (1.1 V vs. 700 mV) and higher reverse leakage current (5 µA vs. 500 nA). These differences affect power dissipation and thermal performance. System-level analysis is required to determine acceptability.

Q: Are both components RoHS compliant?

A: Yes, both the MB16M-BP and DF04M are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions.

Q: What is the operating temperature range difference?

A: The MB16M-BP operates from -55°C to 125°C, while the DF04M extends to 150°C. The DF04M provides a 25°C upper temperature margin, which may be beneficial in thermally constrained applications.

Q: Why is the peak reverse voltage rating of the DF04M (400 V) significantly higher than the MB16M-BP (60 V)?

A: The DF04M is designed for higher voltage applications. In a 60 V system, the excess voltage rating provides design margin but does not affect functional compatibility. Component selection should be based on actual circuit voltage requirements.
