B2M-E3/45 Equivalent & Substitute Parts

Part Overview

The B2M-E3/45 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 200 V peak reverse voltage and 500 mA average rectified current. This component is classified as obsolete, making identification of suitable substitutes essential for ongoing design support and production continuity. The through-hole MBM package configuration requires alternative solutions for applications where component availability or manufacturing process changes necessitate part replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the B2M-E3/45 is determined by electrical equivalence across the following critical parameters:

• Diode Type: Single Phase
• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 1 V @ 500 mA
• Current - Reverse Leakage @ Vr: 5 µA @ 200 V
• Operating Temperature Range: -55°C ~ 150°C (TJ)
• RoHS Status: ROHS3 Compliant

The primary substitute identified is the B2S-E3/80, which maintains electrical equivalence while transitioning from through-hole to surface-mount packaging. This substitution is valid where circuit board design and assembly processes accommodate the TO-269AA package format.

Parameter Comparison

Engineering Selection Recommendations

The B2S-E3/80 is the designated manufacturer substitute for the B2M-E3/45. Both components maintain identical electrical specifications across all critical parameters: 200 V peak reverse voltage, 500 mA average rectified current, 1 V forward voltage drop, and 5 µA reverse leakage current at rated conditions. Both operate across the -55°C to 150°C temperature range and comply with ROHS3 and REACH requirements.

The primary distinction is packaging: the B2M-E3/45 uses through-hole 4-DIP configuration, while the B2S-E3/80 employs surface-mount TO-269AA format. This substitution is valid for new designs or production transitions where surface-mount assembly is feasible. The B2S-E3/80 maintains active product status, ensuring long-term availability compared to the obsolete B2M-E3/45.

Frequently Asked Questions (FAQ)

Q: Can the B2S-E3/80 directly replace the B2M-E3/45 in existing through-hole designs?

A: Electrical substitution is valid; however, physical board layout modification is required. The B2S-E3/80 uses surface-mount TO-269AA packaging, necessitating PCB redesign from through-hole to surface-mount footprint. Direct socket replacement is not possible.

Q: Are the electrical specifications identical between B2M-E3/45 and B2S-E3/80?

A: Yes. Both components are rated for 200 V peak reverse voltage, 500 mA average rectified current, 1 V maximum forward voltage at 500 mA, and 5 µA reverse leakage current at 200 V. Operating temperature range and thermal characteristics are equivalent.

Q: What compliance certifications apply to both parts?

A: Both the B2M-E3/45 and B2S-E3/80 are ROHS3 compliant and REACH unaffected. Moisture sensitivity level is 1 (unlimited) for both components.

Q: Why is the B2M-E3/45 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The B2S-E3/80 represents the active product line continuation with equivalent electrical performance and modern surface-mount packaging.

Q: Are there package-specific considerations for the TO-269AA format?

A: The TO-269AA (MBS) package is a 4-lead surface-mount configuration. PCB layout must accommodate the specific footprint dimensions and thermal management requirements of this package type. Consult the B2S-E3/80 datasheet for precise footprint specifications.
