2W02G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2W02G is a single-phase bridge rectifier manufactured by onsemi, rated for 200 V peak reverse voltage and 2 A average rectified current. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. Bridge rectifiers in this specification class are used in AC-to-DC conversion circuits requiring moderate voltage and current ratings with through-hole mounting.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2W02G is determined by equivalence across the following critical parameters:

• Diode Type & Technology: Single Phase, Standard technology
• Voltage Rating: 200 V peak reverse voltage (Vrrm)
• Current Rating: 2 A average rectified current (Io)
• Forward Voltage Characteristics: 1.1 V maximum at 2 A
• Reverse Leakage: 5 µA at 200 V
• Temperature Range: -55°C to 150°C junction temperature
• Mounting & Package: Through-hole, 4-circular configuration

The substitute part 2W02G-E4/51 maintains identical electrical specifications and mounting characteristics, with the primary distinction being the package variant designation (WOG versus WOB) and active product status.

Engineering Selection Recommendations

The 2W02G-E4/51 from Vishay General Semiconductor - Diodes Division is a direct functional equivalent for the obsolete 2W02G. Selection of this substitute is supported by:

• Identical Electrical Specifications: All voltage, current, and thermal parameters match exactly
• Active Product Status: The substitute maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts share identical REACH and ECCN classifications, with the substitute meeting ROHS3 compliance requirements
• Package Compatibility: Both components use 4-circular through-hole mounting, enabling direct board-level substitution
• Thermal Performance: Operating temperature range and junction temperature specifications are equivalent

The package variant designation change (WOB to WOG) reflects manufacturer-specific packaging standards and does not affect electrical or mechanical compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can the 2W02G-E4/51 be used as a direct replacement for the 2W02G?

A: Yes. The 2W02G-E4/51 meets all electrical and mechanical specifications of the 2W02G. Both components are rated for 200 V peak reverse voltage, 2 A average rectified current, and operate across the same temperature range. Through-hole mounting compatibility is maintained.

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

A: WOB and WOG are manufacturer-specific package variant codes. Both designate 4-circular through-hole bridge rectifier packages with identical electrical and mechanical interfaces. The designation change reflects Vishay's packaging standard versus onsemi's original specification.

Q: Why is the 2W02G listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The 2W02G-E4/51 provides functional continuity for applications requiring this specification class.

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

A: Both parts are REACH Unaffected and classified as EAR99. The 2W02G-E4/51 additionally carries ROHS3 compliance certification, providing enhanced regulatory alignment for new designs.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures for through-hole components apply.
