Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2W10M is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 1 kV
• Current - Average Rectified (Io): 2 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 2 A

Mechanical and Environmental Equivalence Requirements:

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

The substitute part 2W10G-E4/51 meets all electrical and mechanical equivalence criteria. Both components share identical voltage ratings, current ratings, forward voltage characteristics, and through-hole mounting configuration. The 4-circular package geometry remains consistent between the WOM and WOG variants, ensuring direct physical compatibility in existing PCB layouts.

Engineering Selection Recommendations

The 2W10G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division is the specified substitute for the obsolete 2W10M. This substitution is supported by the following factors:

Product Status: The 2W10G-E4/51 maintains active product status, ensuring ongoing availability and manufacturer support. The 2W10M is obsolete, making the Vishay component the appropriate alternative for new designs and continued supply.

Electrical Compatibility: Both components are rated identically for 1 kV peak reverse voltage and 2 A average rectified current. Forward voltage characteristics are equivalent at 1.1 V maximum at 2 A. The 2W10G-E4/51 exhibits lower reverse leakage current (5 µA versus 10 µA at 1000 V), representing an improvement in leakage performance.

Mechanical Compatibility: Both components utilize through-hole mounting with 4-circular package configurations, ensuring direct physical compatibility in existing PCB layouts without modification.

Regulatory Compliance: The 2W10G-E4/51 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both components share identical ECCN and HTSUS classifications.

Temperature Range: The 2W10G-E4/51 supports an extended operating temperature range (-55°C ~ 150°C) compared to the 2W10M (-65°C ~ 125°C), providing broader thermal operating capability.

Frequently Asked Questions (FAQ)

Q: Can the 2W10G-E4/51 be used as a direct replacement for the 2W10M in existing applications?

A: Yes. The 2W10G-E4/51 meets all electrical and mechanical equivalence criteria. Both components share identical voltage ratings (1 kV), current ratings (2 A), forward voltage characteristics (1.1 V @ 2 A), and through-hole 4-circular package configuration. No PCB modifications are required.

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

A: WOM and WOG are manufacturer-specific package variant designations for the 4-circular through-hole bridge rectifier configuration. Both maintain identical physical dimensions and pin configurations, ensuring mechanical interchangeability.

Q: Does the lower reverse leakage current of the 2W10G-E4/51 affect circuit performance?

A: The 2W10G-E4/51 exhibits 5 µA reverse leakage at 1000 V compared to 10 µA for the 2W10M. This represents improved leakage performance and does not negatively impact circuit operation. Applications sensitive to leakage current may benefit from this characteristic.

Q: Are there any compliance or certification differences between the two parts?

A: The 2W10G-E4/51 is ROHS3 compliant and REACH unaffected. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The 2W10M compliance status was not specified in available documentation.

Q: What is the inventory status of these components?

A: The 2W10M has 15,015 pieces in stock as new original inventory. The 2W10G-E4/51 has 7,723 pieces in stock as new original inventory in bulk packaging.

Q: Can the 2W10G-E4/51 operate at the lower temperature limit of the 2W10M (-65°C)?

A: The 2W10G-E4/51 is rated for -55°C minimum operating temperature, which is 10°C higher than the 2W10M minimum of -65°C. Applications requiring operation below -55°C must use the 2W10M or identify alternative components with lower temperature ratings.
