Bridge Rectifier 2W01M Equivalent & Substitute Parts

Part Overview

The 2W01M is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 100 V peak reverse voltage and 2 A average rectified current. This component is classified as Obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and new production requirements. The through-hole WOM package configuration requires compatible alternatives with matching electrical and mechanical specifications to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitute parts for the 2W01M bridge rectifier are identified based on strict electrical and mechanical parameter matching within the allowed specifications for single-phase bridge rectifier diodes. The substitution logic is based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - Peak Reverse (Max): 100 V minimum
• Current - Average Rectified (Io): 2 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower @ 2 A
• Current - Reverse Leakage @ Vr: Must not exceed specified limits
• Diode Type: Single Phase
• Technology: Standard

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole
• Package / Case: 4-Circular configuration
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part 2W01G-E4/51 meets all electrical parameters and maintains through-hole mounting compatibility. Package designation changes from WOM to WOG reflect manufacturer-specific packaging variants while maintaining identical 4-Circular pin configuration and footprint compatibility.

Engineering Selection Recommendations

The 2W01G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division is a direct electrical and mechanical substitute for the obsolete 2W01M. Selection of this substitute is supported by the following engineering factors:

Product Status Alignment: The 2W01G-E4/51 maintains Active product status, ensuring continued availability, technical support, and manufacturing consistency compared to the Obsolete 2W01M.

Electrical Parameter Compliance: All critical electrical specifications match or exceed the 2W01M requirements. The reverse leakage current of 5 µA @ 100 V is lower than the 2W01M specification of 10 µA @ 100 V, indicating improved performance characteristics. Forward voltage remains identical at 1.1 V @ 2 A.

Thermal Performance: The extended operating temperature range of -55 to 150°C (TJ) for the 2W01G-E4/51 provides broader thermal coverage compared to the 2W01M range of -65 to 125°C (TJ), supporting applications across wider environmental conditions.

Compliance Certifications: The 2W01G-E4/51 carries RoHS3 Compliance and REACH Unaffected status, meeting modern regulatory requirements. Both parts share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Packaging Compatibility: The 4-Circular through-hole configuration is maintained between both parts. Package designation variants (WOM vs. WOG) reflect manufacturer-specific nomenclature without affecting physical footprint or pin compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2W01G-E4/51 be used as a direct replacement for the 2W01M in existing circuit boards?

A: Yes. The 2W01G-E4/51 maintains identical electrical ratings (100 V, 2 A) and 4-Circular through-hole package configuration. Physical footprint and pin spacing are compatible with PCB designs originally specified for the 2W01M.

Q: What is the difference between the WOM and WOG package designations?

A: WOM and WOG are manufacturer-specific package variant codes used by GeneSiC and Vishay respectively. Both designations refer to identical 4-Circular through-hole configurations with matching pin assignments and mechanical dimensions.

Q: Does the lower reverse leakage current of the 2W01G-E4/51 affect circuit operation?

A: No. Lower reverse leakage current (5 µA vs. 10 µA @ 100 V) represents improved performance and does not create compatibility issues. Circuits designed for the 2W01M specification will operate within normal parameters with the 2W01G-E4/51.

Q: Are there any temperature range considerations when substituting the 2W01G-E4/51?

A: The 2W01G-E4/51 provides an extended operating temperature range (-55 to 150°C TJ) compared to the 2W01M (-65 to 125°C TJ). This extended range supports broader application environments without introducing compatibility concerns for designs within the original temperature specification.

Q: What compliance certifications apply to the 2W01G-E4/51?

A: The 2W01G-E4/51 is RoHS3 Compliant and REACH Unaffected. Both the 2W01M and 2W01G-E4/51 share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications for export and tariff purposes.

Q: Is the 2W01G-E4/51 available in the same packaging format as the 2W01M?

A: The 2W01G-E4/51 is supplied in Bulk packaging, while the 2W01M inventory information does not specify packaging format. Both parts use identical 4-Circular through-hole package / case configuration suitable for standard PCB assembly processes.
