MB05M-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB05M-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 50 V peak reverse voltage and 800 mA average rectified current. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The through-hole MBM package configuration and standard rectification technology establish the baseline for equivalent part selection.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB05M-G are identified based on the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): Must equal or exceed 50 V
• Current - Average Rectified (Io): Must equal or exceed 800 mA
• Voltage - Forward (Vf) (Max): Must not exceed 1.1 V at rated current
• Current - Reverse Leakage @ Vr: Must not exceed 5 µA @ 50 V
• Operating Temperature Range: Must encompass -55°C ~ 150°C (TJ)
• Diode Type: Single Phase
• Technology: Standard

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package Configuration: 4-pin DIP or equivalent through-hole package

The DF005M-E3/45 meets these substitution criteria with equivalent or superior electrical performance and compatible through-hole mounting.

Engineering Selection Recommendations

The DF005M-E3/45 is the recommended substitute for the obsolete MB05M-G based on the following factors:

Product Status: The DF005M-E3/45 maintains active product status with confirmed inventory availability (3200 pcs), ensuring long-term supply continuity compared to the obsolete MB05M-G.

Electrical Performance: The substitute part meets or exceeds all critical electrical parameters. The 1 A current rating provides margin above the 800 mA requirement of the original design, while maintaining identical voltage ratings and leakage specifications.

Compliance & Certifications: The DF005M-E3/45 is RoHS3 compliant and carries REACH Unaffected status, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Package Consideration: The 4-EDIP package (0.300", 7.62mm pitch) differs from the original 4-DIP (0.200", 5.08mm pitch). PCB layout modification is required for this substitution. The through-hole mounting type remains compatible with existing design approaches.

Frequently Asked Questions (FAQ)

Q: Can the DF005M-E3/45 directly replace the MB05M-G without PCB modifications?

A: The DF005M-E3/45 requires PCB layout changes due to different pin pitch (0.300" vs 0.200"). Pin-to-pin electrical compatibility is maintained, but physical footprint adjustment is necessary.

Q: What is the significance of the higher 1 A current rating on the DF005M-E3/45?

A: The 1 A rating on the substitute part exceeds the 800 mA requirement of the original design. This provides operational margin and does not create compatibility issues in applications designed for 800 mA operation.

Q: Are the forward voltage characteristics identical between these parts?

A: Both parts specify 1.1 V maximum forward voltage at their respective rated currents (800 mA for MB05M-G, 1 A for DF005M-E3/45). This ensures equivalent circuit performance in rectification applications.

Q: What compliance advantages does the DF005M-E3/45 offer?

A: The DF005M-E3/45 is RoHS3 compliant and maintains active product status, providing regulatory alignment and supply security compared to the obsolete MB05M-G.

Q: Are there any thermal or operating range differences?

A: Both parts operate across the identical temperature range of -55°C to 150°C (TJ), ensuring equivalent thermal performance in the specified operating environment.

Q: What packaging format is the DF005M-E3/45 supplied in?

A: The DF005M-E3/45 is supplied in tube packaging, suitable for automated assembly processes and component handling.
