Equivalent & Substitute Parts for 2W08M Bridge Rectifier

Part Overview

The 2W08M is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 800 V peak reverse voltage with 2 A average rectified current. This component is designed for through-hole mounting applications requiring standard rectification technology. The 2W08M is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and procurement planning. Substitute parts must maintain electrical equivalence across voltage, current, and thermal specifications while accommodating packaging and compliance requirements.

Substitute Part Grouping Explanation

Substitution of the 2W08M is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

  • Voltage - Peak Reverse (Max): 800 V
  • Current - Average Rectified (Io): 2 A
  • Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A
  • Diode Type: Single Phase
  • Technology: Standard

Mechanical & Environmental Requirements:

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

Compliance & Certification:

  • ECCN: EAR99
  • HTSUS: 8541.10.0080

The substitute part 2W08G-E4/51 meets all electrical equivalence criteria. Differences in reverse leakage current (5 µA vs. 10 µA) and operating temperature range (-55°C to 150°C vs. -65°C to 125°C) represent improvements over the original specification and do not preclude substitution. Package designation changes from WOM to WOG reflect manufacturer-specific nomenclature while maintaining 4-Circular through-hole configuration compatibility.

Engineering Selection Recommendations

The 2W08G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division is a direct electrical and mechanical substitute for the obsolete 2W08M. Selection of this substitute is supported by the following factors:

Electrical Equivalence: All critical electrical parameters match the original specification, including peak reverse voltage (800 V), average rectified current (2 A), and forward voltage drop (1.1 V @ 2 A). The substitute exhibits lower reverse leakage current (5 µA vs. 10 µA), which represents improved performance characteristics.

Mechanical Compatibility: Both components utilize 4-Circular through-hole packaging suitable for identical PCB footprints and mounting procedures. Package nomenclature differences (WOM vs. WOG) reflect manufacturer-specific designations and do not affect physical or electrical compatibility.

Product Status & Availability: The 2W08G-E4/51 maintains active product status with documented inventory availability (2935 Pcs), ensuring long-term procurement viability compared to the obsolete 2W08M.

Compliance & Certification: Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The 2W08G-E4/51 carries RoHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

Operating Temperature Consideration: The substitute part supports an extended operating temperature range (-55°C to 150°C) compared to the original (-65°C to 125°C). Applications requiring the full lower temperature limit of -65°C must verify system thermal requirements against the substitute's -55°C minimum specification.

Frequently Asked Questions (FAQ)

Q: Can the 2W08G-E4/51 be used as a direct replacement for the 2W08M in existing designs?

A: Yes. The 2W08G-E4/51 meets all electrical equivalence criteria for the 2W08M, including voltage rating (800 V), current rating (2 A), forward voltage (1.1 V @ 2 A), and through-hole 4-Circular packaging. No circuit modifications are required for substitution.

Q: What is the significance of the package designation change from WOM to WOG?

A: WOM and WOG are manufacturer-specific package nomenclature designations used by GeneSiC and Vishay respectively. Both designations refer to identical 4-Circular through-hole configurations with equivalent physical dimensions and electrical performance. The nomenclature change does not affect PCB compatibility or mounting procedures.

Q: Does the lower reverse leakage current of the 2W08G-E4/51 (5 µA vs. 10 µA) affect circuit performance?

A: Lower reverse leakage current represents improved performance characteristics and does not negatively impact circuit operation. Applications designed for the 2W08M specification will operate within acceptable parameters with the substitute part.

Q: Are there temperature range limitations when substituting the 2W08G-E4/51 for the 2W08M?

A: The 2W08G-E4/51 supports an operating temperature range of -55°C to 150°C, compared to the 2W08M range of -65°C to 125°C. Applications requiring operation below -55°C must verify that system thermal requirements do not exceed the substitute part's minimum specification.

Q: What compliance certifications apply to the 2W08G-E4/51?

A: The 2W08G-E4/51 carries RoHS3 compliance and REACH Unaffected status. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) export classifications.

Q: Is the 2W08G-E4/51 available in the same packaging format as the 2W08M?

A: Yes. Both components utilize 4-Circular through-hole packaging. The 2W08G-E4/51 is supplied in Bulk packaging format, maintaining compatibility with standard PCB assembly processes.
