W06G-E4/1 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The W06G-E4/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 600 V peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and new design implementations. The through-hole WOG package configuration and standard rectification technology establish the baseline for compatible alternatives.

Substitute Part Grouping Explanation

Substitute parts for the W06G-E4/1 are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

Voltage - Peak Reverse (Max): 600 V minimum
Diode Type: Single Phase
Technology: Standard
Mounting Type: Through Hole
Operating Temperature Range: -55°C ~ 150°C or wider
RoHS Status: ROHS3 Compliant

The W06G-E4/51 qualifies as a direct substitute, maintaining identical electrical specifications and the same WOG package configuration while offering active product status. The GBU2506-G represents a manufacturer-recommended alternative with higher current capacity (4.2 A vs. 1.5 A), different package geometry (4-SIP GBU vs. 4-Circular WOG), and modified forward voltage characteristics, suitable for applications requiring increased current handling within the same voltage class.

Engineering Selection Recommendations

The W06G-E4/51 is the primary substitute for the obsolete W06G-E4/1, offering identical electrical performance and package compatibility with active product status and ROHS3 compliance. This part maintains the same current rating, voltage specifications, and thermal operating range, enabling direct replacement in existing designs.

The GBU2506-G is a manufacturer-recommended alternative for applications requiring higher current capacity. While it maintains the 600 V voltage rating and single-phase bridge rectifier topology, the increased current rating of 4.2 A accommodates higher load requirements. The different package geometry (4-SIP GBU vs. 4-Circular WOG) requires PCB layout verification. Both substitute options maintain ROHS3 compliance and the -55°C to 150°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the W06G-E4/51 be used as a direct replacement for the W06G-E4/1?

A: Yes. The W06G-E4/51 maintains identical electrical specifications (600 V, 1.5 A, 1 V forward voltage @ 1 A, 5 µA reverse leakage @ 600 V) and uses the same 4-Circular WOG package configuration. The primary difference is product status: W06G-E4/51 is active while W06G-E4/1 is obsolete.

Q: What are the key differences between the W06G-E4/51 and GBU2506-G?

A: Both maintain 600 V peak reverse voltage and -55°C to 150°C operating temperature. The GBU2506-G provides higher current capacity (4.2 A vs. 1.5 A) and different forward voltage characteristics (1 V @ 12.5 A vs. 1 V @ 1 A). Package geometry differs: GBU2506-G uses 4-SIP GBU while W06G-E4/51 uses 4-Circular WOG. Reverse leakage is higher in GBU2506-G (10 µA @ 600 V vs. 5 µA @ 600 V).

Q: Are package differences between WOG and GBU significant for substitution?

A: Yes. WOG and GBU represent different physical package geometries. While both are through-hole configurations, PCB footprint, lead spacing, and mounting hole patterns differ. Physical compatibility must be verified before substitution.

Q: Do all substitute parts meet the same compliance standards?

A: All listed parts are ROHS3 compliant and REACH unaffected. Moisture sensitivity differs: W06G-E4/1 and W06G-E4/51 list MSL as Not Applicable, while GBU2506-G specifies MSL 1 (Unlimited).

Q: Which substitute should be selected for a 1.5 A application?

A: The W06G-E4/51 is the appropriate selection, providing identical current rating and electrical specifications to the obsolete W06G-E4/1 with active product status.
