Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2W02M is determined by electrical and mechanical parameter equivalence across the following criteria:

Electrical Parameters (Critical for Functionality):

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 200 V
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A

Mechanical Parameters (Critical for Installation):

• Mounting Type: Through Hole
• Package / Case: 4-Circular configuration

Environmental Parameters (Critical for Reliability):

• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute part 2W02G-E4/51 satisfies all critical electrical and mechanical parameters. Variations in reverse leakage current and operating temperature range do not preclude substitution when the primary functional requirements are met.

Engineering Selection Recommendations

The 2W02G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division is the designated substitute for the obsolete 2W02M. This substitution is supported by:

Product Status: The 2W02G-E4/51 maintains active product status, ensuring continued availability and manufacturer support, whereas the 2W02M is obsolete.

Electrical Equivalence: Both parts share identical voltage and current ratings (200 V peak reverse, 2 A average rectified current) and forward voltage characteristics (1.1 V @ 2 A), ensuring functional compatibility in existing circuit designs.

Mechanical Compatibility: Both components utilize through-hole mounting with 4-circular package configurations, permitting direct board-level installation without layout modifications.

Compliance and Certifications: Both parts carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The 2W02G-E4/51 is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Environmental Ratings: Both parts maintain MSL 1 (Unlimited) moisture sensitivity classification, indicating equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can the 2W02G-E4/51 directly replace the 2W02M in existing designs?

A: Yes. The 2W02G-E4/51 meets all critical electrical parameters (200 V peak reverse voltage, 2 A average rectified current, 1.1 V forward voltage) and mechanical requirements (through-hole mounting, 4-circular package) of the 2W02M. Direct substitution is supported without circuit modification.

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

A: WOM and WOG are manufacturer-specific package identifiers for the 4-circular through-hole bridge rectifier configuration. Both designations refer to equivalent physical and electrical package standards. The difference reflects manufacturer nomenclature only and does not affect functional compatibility.

Q: Does the lower reverse leakage current of the 2W02G-E4/51 (5 µA vs. 10 µA) affect substitution suitability?

A: No. Lower reverse leakage current represents an improvement in device performance and does not compromise substitution compatibility. The 2W02G-E4/51 operates within acceptable parameters for all applications designed for the 2W02M.

Q: Are there temperature range differences between these parts?

A: The 2W02G-E4/51 operates across -55°C to 150°C, compared to the 2W02M range of -65°C to 125°C. For applications requiring operation below -55°C or above 150°C, the 2W02M specifications must be verified. For standard industrial temperature ranges (-40°C to 85°C), both parts are equivalent.

Q: What compliance certifications apply to the 2W02G-E4/51?

A: The 2W02G-E4/51 is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both parts share identical ECCN (EAR99) export classification.
