W01G Bridge Rectifier Single Phase 100V 1.5A Equivalent & Substitute Parts

Part Overview

The W01G is a single-phase bridge rectifier manufactured by onsemi, rated for 100V peak reverse voltage and 1.5A average rectified current. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The W01G operates across a wide temperature range of -55°C to 150°C and is housed in a 4-Circular WOB through-hole package. Due to its obsolete status, direct replacement with active-production equivalents is necessary for new designs and component replenishment.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the W01G is determined by electrical and mechanical parameter equivalence across the following criteria:

• Single-phase bridge rectifier topology
• 100V peak reverse voltage rating
• 1.5A average rectified current capacity
• 1V maximum forward voltage at 1A
• 5µA maximum reverse leakage current at 100V
• Through-hole mounting configuration
• 4-Circular package form factor
• Operating temperature range of -55°C to 150°C

The W01G-E4/51 manufactured by Vishay General Semiconductor - Diodes Division meets all specified electrical and mechanical parameters, establishing it as a direct equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The W01G-E4/51 is the qualified substitute for the obsolete W01G. Selection is based on:

• Identical electrical performance across all specified parameters
• Active production status ensuring long-term availability
• ROHS3 compliance meeting current regulatory requirements
• Equivalent through-hole mounting and 4-Circular package geometry
• Matching operating temperature specifications
• Shared REACH compliance status

The transition from W01G to W01G-E4/51 requires no circuit redesign, as all functional and thermal characteristics remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can W01G-E4/51 be used as a direct replacement for W01G in existing designs?

A: Yes. The W01G-E4/51 meets all electrical and mechanical specifications of the W01G, including voltage rating, current capacity, forward voltage, reverse leakage, temperature range, and through-hole package configuration. No circuit modifications are required.

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

A: Both designations refer to 4-Circular through-hole packages with identical mechanical and electrical interfaces. The letter suffix indicates the manufacturing variant; both are functionally equivalent for this application.

Q: Why is the W01G classified as obsolete?

A: The W01G has been discontinued by onsemi. The W01G-E4/51 represents the active-production equivalent from Vishay, ensuring continued component availability for new procurement and design support.

Q: Are there compliance differences between W01G and W01G-E4/51?

A: The W01G-E4/51 carries ROHS3 compliance certification, whereas the W01G does not specify RoHS status. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, W01G-E4/51 is the appropriate selection.

Q: What inventory considerations apply to these parts?

A: W01G inventory is limited to 2300 pieces of new original stock. W01G-E4/51 has 4690 pieces available and is actively produced, providing superior long-term supply security.
