DF06S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF06S-HF is a single-phase bridge rectifier diode manufactured by Comchip Technology, rated for 600 V peak reverse voltage and 1 A average rectified current. This component is classified as Active and is currently in stock with 995 pieces available. The DF06S-HF is packaged in a 4-SMD Gull Wing surface mount configuration designated as DFS.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are required for supply chain continuity, or when design revisions call for compatible alternatives that meet identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF06S-HF is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing

Allowable Variation:

• Current - Reverse Leakage @ Vr: Substitute parts may have equal or lower leakage current at 600 V
• Operating Temperature Range: Substitute parts must support the minimum required range of -55°C to 150°C
• Supplier Device Package designation: May differ (DFS, DBS, DF-S) while maintaining mechanical and electrical compatibility

All substitute parts listed below meet or exceed the electrical and mechanical requirements of the DF06S-HF.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

The DF06S manufactured by Fairchild Semiconductor and the DF06S-E3/45 manufactured by Vishay General Semiconductor are the preferred substitute options. Both components are classified as Active products, ensuring continued manufacturer support and long-term availability. The DF06S from Fairchild offers the highest inventory level at 38,560 pieces and supports an extended operating temperature range of -65°C to 150°C, providing additional thermal margin. The DF06S-E3/45 from Vishay features improved reverse leakage characteristics at 5 µA compared to the 10 µA specification of the DF06S-HF, and carries ROHS3 compliance certification.

Secondary Substitutes (Obsolete Status):

The DB105S-G and DF06S-G, both manufactured by Comchip Technology, are classified as Obsolete. These parts maintain full electrical and mechanical compatibility with the DF06S-HF but are no longer in active production. Selection of these parts is appropriate only when existing inventory must be utilized or when design documentation specifically references these part numbers. Both obsolete variants carry ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited) ratings.

Compliance Considerations:

All substitute parts carry EAR99 export classification and HTSUS code 8541.10.0080. The Comchip variants (DB105S-G and DF06S-G) and the Vishay variant (DF06S-E3/45) include ROHS3 compliance and REACH Unaffected status certifications. The Fairchild DF06S does not include these certifications in the provided specifications.

Frequently Asked Questions (FAQ)

Q: Can the DF06S-HF be replaced with the DF06S from Fairchild Semiconductor?

A: Yes. The DF06S from Fairchild Semiconductor meets all electrical and mechanical requirements of the DF06S-HF. Both components share identical voltage ratings (600 V peak reverse), current ratings (1 A average rectified), forward voltage characteristics (1.1 V @ 1 A), and package configuration (4-SMD Gull Wing). The Fairchild variant is classified as Active and maintains the highest inventory availability.

Q: What is the difference between the DF06S-E3/45 from Vishay and the DF06S-HF from Comchip?

A: The DF06S-E3/45 and DF06S-HF are electrically equivalent with one exception: the Vishay part exhibits lower reverse leakage current at 5 µA compared to 10 µA for the Comchip part. Both operate across the same temperature range (-55°C to 150°C) and share identical voltage and current ratings. The Vishay part includes ROHS3 compliance certification.

Q: Why are the DB105S-G and DF06S-G listed as Obsolete?

A: The DB105S-G and DF06S-G are no longer manufactured by Comchip Technology. These parts are retained in the substitute list because they maintain full parametric equivalence to the DF06S-HF and may be selected when existing inventory is available or when design documentation specifically requires these part numbers.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts use the same 4-SMD Gull Wing surface mount package configuration. However, packaging designation differs: the DF06S-HF uses DFS packaging, the DB105S-G uses DBS packaging, and the Fairchild DF06S uses DF-S packaging. These designations reflect supplier conventions but do not affect mechanical or electrical compatibility.

Q: Can the DF06S-HF be used in applications requiring ROHS3 compliance?

A: The DF06S-HF specifications provided do not include ROHS3 compliance certification. For applications requiring ROHS3 compliance, the DB105S-G, DF06S-G, or DF06S-E3/45 are appropriate substitutes, as all three carry ROHS3 compliance documentation.

Q: What is the operating temperature advantage of the Fairchild DF06S?

A: The Fairchild DF06S supports an operating temperature range of -65°C to 150°C, compared to -55°C to 150°C for the DF06S-HF. This provides an additional 10°C of low-temperature margin, which may be beneficial in applications exposed to extreme cold environments.
