DF005S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF005S-HF is a single-phase bridge rectifier manufactured by Comchip Technology, designed for surface mount applications. This component operates at 50 V peak reverse voltage with 1 A average rectified current capacity. The part is currently in active product status with 1,043 units in stock.

Substitute parts are identified based on matching electrical performance parameters and mechanical compatibility. Alternative models may be required due to supply chain considerations, manufacturing transitions, or specific application requirements where equivalent electrical characteristics are maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF005S-HF are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Voltage - Peak Reverse (Max): 50 V
• Current - Average Rectified (Io): 1 A
• Diode Type: Single Phase
• Technology: Standard
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -55°C to 150°C (TJ)

Parts meeting these specifications are electrically and mechanically interchangeable. Variations in reverse leakage current (within the specified range) and packaging format (tube versus other configurations) do not affect functional substitution capability.

Engineering Selection Recommendations

DF005S-HF (Primary Part - Active Status)

The DF005S-HF is the recommended selection for new designs and ongoing production. This part maintains active product status with Comchip Technology and provides full electrical and mechanical compatibility with all identified substitutes.

DF005S-E3/45 (Active Alternative)

The DF005S-E3/45 manufactured by Vishay General Semiconductor - Diodes Division is an active product offering equivalent electrical performance. This part features improved reverse leakage characteristics (5 µA @ 50 V versus 10 µA @ 50 V) and carries ROHS3 compliance certification. This substitute is suitable for applications requiring enhanced leakage specifications or where Vishay component qualification is required.

DB101S-G and DF005S-G (Obsolete Status)

Both DB101S-G and DF005S-G are classified as obsolete products. These parts maintain electrical equivalence to the DF005S-HF but are no longer in active production. Selection of these parts is limited to legacy system support or where existing inventory must be utilized. DB101S-G uses a DBS supplier device package variant while DF005S-G uses the DFS package matching the primary part.

Frequently Asked Questions (FAQ)

Q: Can DF005S-E3/45 be used as a direct replacement for DF005S-HF?

A: Yes. The DF005S-E3/45 meets all critical electrical parameters: 50 V peak reverse voltage, 1 A average rectified current, 1.1 V forward voltage at 1 A, and identical operating temperature range. The 4-SMD gull wing package is mechanically compatible. The lower reverse leakage current (5 µA) represents improved performance characteristics.

Q: What is the difference between DB101S-G and DF005S-G?

A: Both parts are electrically equivalent to DF005S-HF with identical voltage, current, and temperature specifications. The primary difference is the supplier device package designation: DB101S-G uses DBS packaging while DF005S-G uses DFS packaging. Both are obsolete products.

Q: Are there packaging format differences between these substitutes?

A: The DF005S-HF is supplied in standard packaging format. Substitute parts DB101S-G, DF005S-G, and DF005S-E3/45 are supplied in tube packaging. All parts share identical 4-SMD gull wing mechanical configuration suitable for surface mount assembly.

Q: Does the DF005S-E3/45 require different PCB layout or assembly procedures?

A: No. The DF005S-E3/45 maintains the same 4-SMD gull wing package footprint and mounting type as the DF005S-HF. PCB layout, assembly procedures, and reflow profiles remain unchanged.

Q: What compliance certifications apply to these substitute parts?

A: The DF005S-E3/45, DB101S-G, and DF005S-G all carry ROHS3 compliance certification with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status. These certifications support applications requiring environmental and regulatory compliance documentation.

Q: Why would I select an obsolete part over an active product?

A: Obsolete parts (DB101S-G, DF005S-G) are selected only when existing inventory must be consumed or when legacy system support requires component continuity. For new designs and ongoing production, active products (DF005S-HF or DF005S-E3/45) are the appropriate selection.
