W02G Bridge Rectifier Single Phase 200V 1.5A Equivalent & Substitute Parts

Part Overview

The W02G is a single-phase bridge rectifier manufactured by onsemi, rated for 200 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The W02G operates across a temperature range of -55°C to 150°C and is packaged in a 4-Circular WOB through-hole configuration. Locating active equivalent parts ensures design flexibility and supply chain reliability for applications requiring this rectification specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the W02G is determined by electrical and mechanical parameter equivalence across the following criteria:

• Voltage Rating: Peak reverse voltage must equal 200 V
• Current Rating: Average rectified current must equal 1.5 A
• Forward Voltage Characteristics: Maximum forward voltage of 1 V @ 1 A
• Reverse Leakage: Maximum reverse leakage of 5 µA @ 200 V
• Temperature Range: Operating range of -55°C to 150°C
• Diode Configuration: Single-phase bridge rectifier topology
• Mounting: Through-hole package type
• Package Form Factor: 4-Circular configuration

The W02G-E4/51 meets all specified electrical parameters and maintains mechanical compatibility through equivalent through-hole packaging, establishing it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The W02G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division is the qualified substitute for the obsolete W02G. This part maintains identical electrical specifications across all critical parameters: 200 V peak reverse voltage, 1.5 A average rectified current, 1 V forward voltage drop, and 5 µA reverse leakage. Both components operate within the same temperature envelope of -55°C to 150°C and share equivalent through-hole mounting characteristics.

The W02G-E4/51 holds active product status, ensuring ongoing availability and manufacturing support. Both parts carry REACH Unaffected status and EAR99 export classification, maintaining regulatory alignment. The W02G-E4/51 is RoHS3 compliant, providing additional environmental compliance assurance. The package form factor difference (WOG versus WOB) does not affect electrical or mechanical interchangeability within the 4-Circular through-hole configuration.

Frequently Asked Questions (FAQ)

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

A: Yes. The W02G-E4/51 meets all electrical specifications of the W02G, including voltage rating, current capacity, forward voltage characteristics, and reverse leakage parameters. Both components are rated for -55°C to 150°C operation and use through-hole mounting. The parts are electrically and mechanically interchangeable.

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

A: Both WOB and WOG refer to 4-Circular through-hole package configurations. The letter designation indicates the specific manufacturer's package variant. These variants do not affect electrical performance or through-hole mounting compatibility.

Q: Why is the W02G listed as obsolete?

A: The W02G has been discontinued by onsemi. The W02G-E4/51 from Vishay maintains the same electrical and mechanical specifications while remaining in active production, providing continuity for applications requiring this rectifier specification.

Q: Are there any compliance differences between the W02G and W02G-E4/51?

A: Both parts carry REACH Unaffected status and EAR99 export classification. The W02G-E4/51 is additionally RoHS3 compliant. Both components have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Q: What inventory status should be considered when selecting between these parts?

A: The W02G has 939 pieces available as new original stock. The W02G-E4/51 has 1900 pieces available as new original stock. Given the obsolete status of the W02G, the W02G-E4/51 is the recommended selection for new designs and ongoing procurement.
