BR64 Bridge Rectifier Single Phase 400V 6A Equivalent & Substitute Parts

Part Overview

The BR64 is a single-phase bridge rectifier manufactured by GeneSiC Semiconductor, rated for 400V peak reverse voltage and 6A average rectified current. This component is classified as Active product status and is RoHS Compliant. Bridge rectifiers in this voltage and current class are used in AC-to-DC conversion applications requiring through-hole mounting and standard rectification technology. Substitute parts become necessary when primary inventory is unavailable, when design requirements permit alternative manufacturers, or when specific compliance certifications are required for end-application qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BR64 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Diode Type: Single Phase
• Technology: Standard
• Voltage - Peak Reverse (Max): 400 V
• Current - Average Rectified (Io): 6 A
• Mounting Type: Through Hole
• Package / Case: 4-Square configuration

Allowable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: Permitted to vary within standard rectifier specifications
• Current - Reverse Leakage @ Vr: Permitted to vary within standard rectifier specifications
• Operating Temperature Range: Permitted to vary; substitute must support application temperature requirements
• RoHS/Compliance Status: Permitted to vary; selection depends on end-application regulatory requirements

The PB64-BP manufactured by Micro Commercial Co meets all mandatory matching parameters and qualifies as an electrical and mechanical equivalent to the BR64.

Parameter Comparison

Engineering Selection Recommendations

BR64 Selection Criteria: The BR64 is the primary choice for new designs. It carries Active product status, indicating ongoing manufacturer support and availability. The component is RoHS Compliant and suitable for applications requiring long-term supply chain stability.

PB64-BP Selection Criteria: The PB64-BP is electrically and mechanically equivalent and qualifies as a substitute part. However, it carries "Not For New Designs" product status, indicating the manufacturer has discontinued active development and support. The PB64-BP is suitable for:

• Replacement or repair of existing equipment using PB64-BP components
• Applications where inventory of the original part is exhausted and immediate substitution is required
• Legacy system maintenance where design re-qualification is not feasible

Compliance Considerations: Both parts are RoHS compliant. The BR64 is RoHS Compliant (standard). The PB64-BP is ROHS3 Compliant and REACH Unaffected, providing additional regulatory coverage for certain end-markets.

Temperature Range Consideration: The PB64-BP supports a wider operating temperature range (-55°C to 150°C) compared to the BR64 (-65°C to 125°C). For applications operating above 125°C or below -55°C, verify component suitability against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the PB64-BP replace the BR64 in a new design? A: Electrically and mechanically, yes. The PB64-BP meets all mandatory parameter requirements. However, the PB64-BP carries "Not For New Designs" status. New designs should specify the BR64 to ensure long-term manufacturer support and supply chain continuity.

Q: Are the BR-6 and PB-6 packages mechanically interchangeable? A: Both packages are 4-Square through-hole configurations and are mechanically compatible for PCB mounting. Verify footprint dimensions against your PCB design to confirm fit.

Q: What is the difference in forward voltage between BR64 and PB64-BP? A: The BR64 has a maximum forward voltage of 1.0 V @ 3 A, while the PB64-BP is rated at 1.1 V @ 3 A. This 0.1 V difference is within standard rectifier specifications and does not affect functional equivalence for typical AC-to-DC conversion applications.

Q: Which part should I use for a replacement in an existing system? A: If the system currently uses PB64-BP components, the PB64-BP is the direct replacement. If the system uses BR64 components, the BR64 is the recommended replacement. Cross-substitution is electrically valid but should be verified against your specific application thermal and electrical requirements.

Q: Are both parts RoHS compliant? A: Yes. The BR64 is RoHS Compliant. The PB64-BP is ROHS3 Compliant, which provides equivalent environmental compliance with additional regulatory coverage.

Q: What does "Not For New Designs" mean for the PB64-BP? A: This designation indicates that Micro Commercial Co has discontinued active development and support for the PB64-BP. The part remains available in inventory but is not recommended for new product designs. Existing systems using this part can continue to operate and be serviced with available stock.
