MB110M-BP Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The MB110M-BP is a single-phase bridge rectifier manufactured by Micro Commercial Co, rated for 100 V peak reverse voltage and 1 A average rectified current. This component utilizes Schottky technology and is housed in a 4-DIP (0.200", 5.08mm) through-hole package. The product is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MB110M-BP is determined by the following critical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Mounting Type: Through Hole technology for PCB integration
• Package Compatibility: 4-DIP form factor (physical footprint and pin count)
• Voltage Rating: Peak reverse voltage capability must meet or exceed 100 V
• Current Rating: Average rectified current capacity must meet or exceed 1 A
• Operating Temperature Range: Must support -55°C to 150°C junction temperature
• RoHS Compliance: ROHS3 Compliant status for regulatory alignment

The DF08M from onsemi qualifies as a substitute based on these parameters. While it exhibits higher voltage (800 V) and current (1.5 A) ratings, these represent design margins that do not compromise functionality in applications specified for the MB110M-BP. Both components share identical mounting type, through-hole technology, and compatible package classification.

Parameter Comparison

Engineering Selection Recommendations

Both the MB110M-BP and DF08M are classified as obsolete products. Selection between these components should be based on the following criteria:

MB110M-BP is appropriate when:

• Original component specifications must be maintained for legacy system compatibility
• Inventory availability is confirmed (845 Pcs reported in stock)
• Schottky technology characteristics are required for the application

DF08M is appropriate when:

• Higher voltage and current margins are acceptable within the application design
• Larger package footprint (4-EDIP vs. 4-DIP) can be accommodated on the PCB
• onsemi component availability is preferred (8292 Pcs reported in stock)
• Standard rectifier technology meets application requirements

Both components maintain ROHS3 compliance and identical operating temperature ranges, ensuring regulatory and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can DF08M directly replace MB110M-BP on the same PCB?

A: Physical replacement requires PCB layout verification. The DF08M uses a 4-EDIP package (0.300", 7.62mm pitch) compared to the MB110M-BP 4-DIP package (0.200", 5.08mm pitch). Pin spacing differs, requiring either PCB modification or adapter solutions.

Q: What is the functional difference between Schottky and Standard bridge rectifier technology?

A: Both technologies perform single-phase rectification. The MB110M-BP (Schottky) exhibits lower forward voltage (850 mV @ 1 A) compared to the DF08M (1.1 V @ 1 A). Schottky technology typically provides faster switching characteristics and reduced power dissipation in high-frequency applications.

Q: Are both components suitable for new designs?

A: Both components carry obsolete product status. For new designs, consultation with component distributors regarding long-term availability and consideration of current-generation bridge rectifier alternatives is recommended.

Q: What does ROHS3 Compliant status indicate?

A: ROHS3 compliance certifies that the component meets Restriction of Hazardous Substances Directive requirements, restricting lead, cadmium, mercury, and other hazardous materials. Both components meet this regulatory standard.

Q: How do voltage and current ratings affect substitution?

A: The DF08M provides higher ratings (800 V / 1.5 A) than the MB110M-BP (100 V / 1 A). Higher ratings do not prevent substitution in applications designed for lower specifications, as the component will operate within its safe operating area. However, application-specific requirements must be verified.
