MB6M-G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB6M-G is a single-phase bridge rectifier manufactured by Comchip Technology, rated for 600 V peak reverse voltage and 800 mA average rectified current. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. Bridge rectifiers in this voltage and current class are widely used in AC-to-DC conversion applications requiring through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB6M-G is determined by the following critical parameters:

• Voltage Rating: Peak reverse voltage must be 600 V or greater
• Current Rating: Average rectified current must meet or exceed 800 mA
• Diode Type: Single-phase bridge rectifier configuration
• Technology: Standard rectifier technology
• Mounting: Through-hole package required
• Forward Voltage: Maximum forward voltage drop at rated current
• Reverse Leakage: Leakage current characteristics at rated voltage
• Temperature Range: Operating temperature capability from -55°C to 150°C

The DF06M from onsemi meets all substitution criteria. While the DF06M features a higher current rating (1.5 A) and different package dimensions (4-EDIP 0.300" vs. 4-DIP 0.200"), both components share identical voltage ratings, forward voltage characteristics, reverse leakage specifications, and temperature operating range. The increased current capacity of the DF06M provides design margin for the 800 mA application requirement.

Parameter Comparison

Engineering Selection Recommendations

The DF06M is a direct functional substitute for the MB6M-G based on electrical parameter equivalence. Both components are classified as obsolete, indicating neither is in active production. The DF06M carries RoHS3 compliance certification, whereas the MB6M-G status is not specified in available documentation. Both components are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.10.0080.

The primary design consideration is package footprint compatibility. The DF06M uses a 4-EDIP package with 0.300" (7.62 mm) lead spacing, compared to the MB6M-G 4-DIP package with 0.200" (5.08 mm) spacing. PCB layout modifications are required if substituting the DF06M into existing MB6M-G designs. The DF06M's higher current rating (1.5 A vs. 800 mA) provides additional thermal and electrical margin for the application.

Frequently Asked Questions (FAQ)

Q: Can the DF06M directly replace the MB6M-G without circuit modifications?

A: Electrical parameters are compatible. However, package dimensions differ: the DF06M uses 4-EDIP (0.300" spacing) versus the MB6M-G 4-DIP (0.200" spacing). PCB layout changes are necessary for physical mounting.

Q: What is the significance of the higher current rating on the DF06M?

A: The DF06M is rated for 1.5 A average rectified current, exceeding the MB6M-G 800 mA requirement. This provides design margin and may reduce thermal stress in the application, but does not alter functional compatibility for 800 mA operation.

Q: Are both components suitable for new designs?

A: Both the MB6M-G and DF06M are classified as obsolete. For new designs, current-production bridge rectifier alternatives should be evaluated through component distributors.

Q: How do forward voltage characteristics compare?

A: Both components specify 1.1 V maximum forward voltage. The MB6M-G is rated at 800 mA, while the DF06M is rated at 1 A. Forward voltage drop remains equivalent across the 800 mA operating point.

Q: What compliance differences exist between these components?

A: The DF06M carries RoHS3 compliance certification. Both components are REACH Unaffected. Compliance requirements for your application should determine component selection if regulatory status is a design criterion.
