Equivalent & Substitute Parts for W10G/1 Bridge Rectifier

Part Overview

The W10G/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, rated for 1 kV peak reverse voltage and 1.5 A average rectified current. This component is classified as obsolete, which necessitates identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part features a 4-circular WOG package configuration suitable for through-hole mounting applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the W10G/1 is determined by the following critical parameters:

• Single-phase bridge rectifier topology
• 1 kV peak reverse voltage rating
• Through-hole mounting configuration
• Operating temperature range of -55°C to 150°C

The W10G-E4/51 qualifies as a parametric equivalent, maintaining identical electrical specifications and package configuration while offering active product status and improved compliance. The GBU2510-G functions as a manufacturer-recommended alternative, sharing the same voltage rating and temperature range but with enhanced current capacity (25 A versus 1.5 A) and different package geometry (4-SIP GBU versus 4-Circular WOG).

Parameter Comparison

Engineering Selection Recommendations

The W10G-E4/51 is the direct parametric equivalent for the obsolete W10G/1, offering identical electrical performance and package configuration with the advantage of active product status and ROHS3 compliance. This part is suitable for direct replacement in applications requiring 1.5 A rectified current at 1 kV.

The GBU2510-G is a manufacturer-recommended alternative that accommodates higher current requirements (25 A) while maintaining the same voltage rating and temperature range. Selection of this part requires verification that the application circuit can accommodate the different package geometry (4-SIP GBU versus 4-Circular WOG) and that the enhanced current capacity does not introduce thermal or performance concerns in the target application.

Both substitute parts maintain compliance with REACH and EAR99 export classifications consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can the W10G-E4/51 be used as a direct replacement for the W10G/1?

A: Yes. The W10G-E4/51 maintains identical electrical specifications, operating temperature range, and package configuration. The primary differences are active product status and ROHS3 compliance, making it suitable for direct substitution.

Q: What are the key differences between the W10G-E4/51 and GBU2510-G?

A: The W10G-E4/51 matches the original W10G/1 specifications exactly with 1.5 A current rating and 4-circular WOG package. The GBU2510-G provides higher current capacity (25 A) and uses a 4-SIP GBU package configuration. Both share the same 1 kV voltage rating and -55°C to 150°C operating temperature range.

Q: Are there package compatibility considerations when selecting a substitute?

A: Yes. The W10G-E4/51 uses the same 4-circular WOG package as the original part and requires no PCB layout modifications. The GBU2510-G uses a 4-SIP GBU package, which has different pin spacing and footprint geometry and requires PCB redesign.

Q: What is the significance of the product status change from obsolete to active?

A: Active product status ensures ongoing availability, manufacturing support, and compliance with current regulatory standards. The W10G-E4/51 and GBU2510-G are both active products with established supply chains.

Q: Do the substitute parts maintain the same compliance certifications?

A: Both substitute parts maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original W10G/1. The W10G-E4/51 and GBU2510-G are both ROHS3 compliant, whereas the original part is RoHS non-compliant.
