Key Parameters

Substitute Part Grouping Explanation

Substitution of the W02M bridge rectifier is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 1.5 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole

Mechanical Compatibility Criteria:

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

The W02G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division meets all electrical and mechanical substitution criteria. Both components share identical voltage and current ratings, single-phase bridge rectifier topology, standard technology classification, and through-hole mounting configuration. The 4-circular package designation ensures mechanical interchangeability in PCB layouts designed for the W02M.

Engineering Selection Recommendations

The W02G-E4/51 is the qualified substitute for the obsolete W02M bridge rectifier. Selection is based on the following engineering factors:

Product Status: The W02M is obsolete, while the W02G-E4/51 maintains active product status with confirmed inventory availability (1900 Pcs New Original In Stock). This ensures long-term supply chain viability for production and maintenance applications.

Electrical Equivalence: Both components share identical peak reverse voltage (200 V), average rectified current (1.5 A), forward voltage drop (1 V @ 1 A), and single-phase bridge rectifier topology. These parameters ensure functional interchangeability in circuit designs.

Compliance and Certifications: The W02G-E4/51 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements. Both components carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Performance Characteristics: The W02G-E4/51 demonstrates superior reverse leakage current (5 µA @ 200 V versus 10 µA @ 200 V) and an extended operating temperature range (-55 to 150 °C versus -65 to 125 °C), providing enhanced performance margins in thermal and leakage-sensitive applications.

Mechanical Compatibility: Both components utilize 4-circular through-hole packages with identical moisture sensitivity levels (MSL 1, Unlimited), ensuring direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the W02G-E4/51 be used as a direct replacement for the W02M in existing designs?

A: Yes. The W02G-E4/51 is electrically and mechanically equivalent to the W02M across all critical parameters: 200 V peak reverse voltage, 1.5 A average rectified current, single-phase bridge rectifier topology, and 4-circular through-hole package configuration. No circuit modifications are required.

Q: What is the difference in reverse leakage current between these two parts?

A: The W02M specifies 10 µA @ 200 V reverse leakage, while the W02G-E4/51 specifies 5 µA @ 200 V. The W02G-E4/51 exhibits lower reverse leakage, which may provide improved performance in applications sensitive to leakage current.

Q: Are there temperature range differences between the W02M and W02G-E4/51?

A: Yes. The W02M operates from -65 to 125 °C (TJ), while the W02G-E4/51 operates from -55 to 150 °C (TJ). The W02G-E4/51 provides an extended upper temperature limit, beneficial for high-temperature applications.

Q: Is the W02G-E4/51 compliant with current regulatory standards?

A: Yes. The W02G-E4/51 is RoHS3 Compliant and REACH Unaffected. Both the W02M and W02G-E4/51 share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

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

A: Both WOM and WOG designations refer to 4-circular through-hole package configurations. The letter suffix indicates the manufacturer's internal package designation (WOM for GeneSiC, WOG for Vishay). The physical package dimensions and PCB footprint remain equivalent.

Q: Is the W02G-E4/51 available in stock?

A: Yes. The W02G-E4/51 is listed as Active product status with 1900 Pcs New Original In Stock, ensuring immediate availability for procurement.

Q: What is the moisture sensitivity level for the W02G-E4/51?

A: The W02G-E4/51 carries MSL 1 (Unlimited) classification, identical to the W02M. This indicates no moisture sensitivity restrictions and no special storage or handling requirements.
