2W10G-E4/51 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The 2W10G-E4/51 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division, designed for standard 1 kV applications with a 2 A average rectified current rating. This component is classified as Active and maintains full RoHS3 compliance with unlimited moisture sensitivity level (MSL 1). Bridge rectifiers of this specification are essential in power supply circuits, battery charging systems, and AC-to-DC conversion applications where single-phase rectification is required. Equivalent and substitute parts are identified based on matching core electrical parameters and mechanical compatibility within the Through Hole mounting category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2W10G-E4/51 are identified based on the following critical parameters that determine functional compatibility:

• Diode Type: Single Phase (required match)
• Technology: Standard (required match)
• Voltage - Peak Reverse (Max): 1 kV (required match)
• Mounting Type: Through Hole (required match)
• Operating Temperature Range: -55°C ~ 150°C (required match)
• RoHS Status: ROHS3 Compliant (required match)

The GBU2510-G from Comchip Technology meets all critical substitution criteria. While the current rating differs (25 A vs. 2 A), this represents an uprated capability suitable for applications requiring the 2W10G-E4/51, as higher current-rated components can operate safely in lower-current applications. The forward voltage and reverse leakage specifications remain within acceptable ranges for standard bridge rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2W10G-E4/51 and GBU2510-G maintain Active product status and full ROHS3 compliance, confirming their suitability for current design requirements. The GBU2510-G offers higher current capacity (25 A vs. 2 A), making it suitable for applications where the 2W10G-E4/51 is specified, provided circuit design accommodates the different package form factor (4-SIP GBU vs. 4-Circular WOG). Selection between these parts should be based on PCB layout constraints, available inventory, and mechanical mounting requirements specific to the application.

Frequently Asked Questions (FAQ)

Q: Can the GBU2510-G directly replace the 2W10G-E4/51 in my circuit?

A: The GBU2510-G is electrically compatible for applications requiring the 2W10G-E4/51, as it maintains identical peak reverse voltage (1 kV), operating temperature range (-55°C ~ 150°C), and technology classification (Standard, Single Phase). However, the package form factor differs (4-SIP GBU vs. 4-Circular WOG), requiring PCB layout verification before substitution.

Q: Why does the GBU2510-G have a higher current rating (25 A vs. 2 A)?

A: The GBU2510-G is an uprated variant within the same product family. Higher current-rated bridge rectifiers can operate safely in lower-current applications without performance degradation, provided thermal management and circuit design remain appropriate.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2W10G-E4/51 and GBU2510-G are ROHS3 Compliant with unlimited moisture sensitivity level (MSL 1), meeting current environmental and regulatory requirements.

Q: What is the difference between WOG and GBU package types?

A: WOG (4-Circular) and GBU (4-SIP) are different mechanical package configurations for bridge rectifiers. Both are Through Hole mounting types, but they have different physical dimensions and pin layouts. PCB design must accommodate the specific package geometry of the selected part.

Q: Can I use the GBU2510-G if my application only requires 2 A?

A: Yes. The GBU2510-G is rated for 25 A average rectified current, so it will operate safely at 2 A. The component will not be thermally stressed at lower current levels, provided the application's voltage and temperature requirements remain within specification.
