DBA500G Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DBA500G is a single-phase bridge rectifier manufactured by onsemi, rated for 600 V peak reverse voltage and 50 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 mounting configuration and 4-Square GBPC-W package form factor define the mechanical and electrical interface requirements for compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DBA500G is determined by strict equivalence across the following electrical and mechanical parameters:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 50 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Through Hole
• Package / Case: 4-Square, GBPC-W

The GBPC5006W-G from Comchip Technology meets all these criteria. Both components share identical voltage and current ratings, the same package form factor, and compatible thermal operating ranges. The forward voltage specification of the substitute (1.1 V @ 25 A) remains within acceptable tolerance for bridge rectifier applications and does not compromise circuit performance.

Parameter Comparison

Engineering Selection Recommendations

The GBPC5006W-G is a direct functional equivalent to the DBA500G. The substitute component carries active product status from Comchip Technology, ensuring ongoing availability and supply chain continuity. Both parts maintain REACH Unaffected compliance status. The GBPC5006W-G provides an extended operating temperature range (-55°C to 150°C) compared to the DBA500G specification, offering additional thermal margin in applications requiring lower temperature operation. Packaging is supplied in tray format for the substitute, which may require adjustment to assembly processes if the original design specified alternative packaging configurations.

Frequently Asked Questions (FAQ)

Q: Can the GBPC5006W-G replace the DBA500G in existing designs?

A: Yes. Both components share identical voltage ratings (600 V), current ratings (50 A), diode type (single phase), and package form factor (4-Square GBPC-W). The electrical and mechanical interfaces are fully compatible.

Q: What is the difference in forward voltage between these parts?

A: The DBA500G specifies 1.05 V maximum forward voltage at 25 A, while the GBPC5006W-G specifies 1.1 V at the same current. This 0.05 V difference is within normal tolerance for bridge rectifier applications and does not affect circuit functionality.

Q: Why is the DBA500G listed as obsolete?

A: Obsolete status indicates the manufacturer (onsemi) has discontinued production. The GBPC5006W-G maintains active status, ensuring continued availability for new designs and replacement applications.

Q: Are there packaging considerations when switching to the GBPC5006W-G?

A: The substitute is supplied in tray packaging, whereas the original part number does not specify packaging format. Verify that tray packaging is compatible with your assembly process and handling requirements.

Q: Do both parts meet the same compliance standards?

A: Both the DBA500G and GBPC5006W-G maintain REACH Unaffected status and share the same ECCN (EAR99) and HTSUS classification (8541.10.0080).
