DF10S-HF Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF10S-HF is a single-phase bridge rectifier diode manufactured by Comchip Technology, rated for 1 kV peak reverse voltage and 1 A average rectified current. This component is classified as Active product status and is currently in stock with 984 pieces available. Bridge rectifiers of this specification are used in power supply circuits, battery chargers, and AC-to-DC conversion applications requiring standard rectification performance.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when specific packaging or compliance requirements necessitate component selection from equivalent alternatives that maintain identical electrical performance within the defined parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF10S-HF is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Parameters:

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

Acceptable Variation Parameters:

• Voltage - Forward (Vf) (Max) @ If: 1.1 V maximum at 1 A (some substitutes specify 1.1 V)
• Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 1000 V (lower leakage is acceptable)
• Supplier Device Package designation: DFS, DBS, or SDIP (different internal package codes for equivalent form factors)
• Packaging format: Tube or unspecified (does not affect electrical compatibility)
• Product Status: Active or Obsolete (electrical performance remains equivalent)

All identified substitute parts meet these criteria and are electrically and mechanically interchangeable with the DF10S-HF in applications requiring 1 kV, 1 A single-phase bridge rectification.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (Preferred): DB107S-HF (Comchip Technology) and DB107S (MDD) are recommended as primary substitutes. Both components maintain Active product status, ensuring long-term availability and supply chain stability. DB107S-HF is available in Tube packaging with 982 pieces in stock, while DB107S from MDD offers the highest inventory level at 44,552 pieces, providing superior supply chain security for high-volume applications.

Secondary Selection (Alternative Manufacturers): DF10S-E3/45 and DF10SA-E3/45 from Vishay General Semiconductor - Diodes Division are qualified substitutes with improved reverse leakage characteristics (5 µA versus 10 µA @ 1000 V). These components are Active status with substantial inventory (35,300 and 3,419 pieces respectively) and are suitable for applications where lower leakage current provides performance benefits.

Tertiary Selection (Limited Availability): DI1010_T0_00001 from Panjit International Inc. is an electrically equivalent substitute with 916 pieces in stock. This component features improved reverse leakage (5 µA) and is suitable for applications requiring supply chain diversification across multiple manufacturers.

Obsolete Status Consideration: DB107S-G (Comchip Technology) carries Obsolete product status despite electrical equivalence. This component is not recommended for new designs or long-term production applications due to discontinued manufacturer support, though it remains electrically compatible for legacy system repairs.

All substitute parts carry ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and REACH Unaffected status, ensuring regulatory compliance across industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can DF10S-HF be directly replaced with DB107S-HF without circuit modification?

A: Yes. DB107S-HF is a direct electrical and mechanical substitute. Both components share identical voltage ratings (1 kV), current ratings (1 A), forward voltage characteristics (1.1 V @ 1 A), operating temperature range (-55°C to 150°C), and package configuration (4-SMD, Gull Wing). No circuit modifications are required.

Q: What is the difference between DF10S-HF and DF10S-E3/45?

A: Both components are electrically equivalent with identical voltage and current ratings. The primary difference is reverse leakage current: DF10S-HF specifies 10 µA @ 1000 V, while DF10S-E3/45 specifies 5 µA @ 1000 V. DF10S-E3/45 offers superior leakage performance and is manufactured by Vishay rather than Comchip. Both are Active status with Surface Mount, 4-SMD Gull Wing packaging.

Q: Why is DB107S-G listed as Obsolete when it is electrically identical to DF10S-HF?

A: DB107S-G is electrically and mechanically equivalent to DF10S-HF but carries Obsolete product status from the manufacturer. This designation indicates discontinued production and support. While the component remains electrically functional, it is not recommended for new designs due to limited future availability and lack of manufacturer technical support.

Q: Are there inventory differences between substitute options?

A: Yes. DB107S (MDD) offers the highest inventory at 44,552 pieces. DB107S-HF (Comchip) provides 982 pieces, DF10S-E3/45 (Vishay) provides 35,300 pieces, and DF10SA-E3/45 (Vishay) provides 3,419 pieces. DI1010_T0_00001 (Panjit) has 916 pieces available. Selection based on inventory availability is appropriate for high-volume production requirements.

Q: Can DF10S-HF be used in applications requiring lower reverse leakage current?

A: DF10S-HF specifies 10 µA reverse leakage @ 1000 V. Applications requiring lower leakage should use DF10S-E3/45, DF10SA-E3/45, or DI1010_T0_00001, all of which specify 5 µA @ 1000 V. These alternatives maintain all other electrical and mechanical equivalence while providing improved leakage performance.

Q: What packaging formats are available for these substitutes?

A: DF10S-HF packaging is unspecified. DB107S-HF, DF10S-E3/45, DF10SA-E3/45, and DI1010_T0_00001 are supplied in Tube packaging. DB107S-G packaging is unspecified. All components use identical 4-SMD, Gull Wing surface mount package configuration, ensuring mechanical compatibility regardless of packaging format.

Q: Are all substitute parts RoHS compliant?

A: DB107S-HF, DB107S, DF10S-E3/45, DF10SA-E3/45, and DI1010_T0_00001 are ROHS3 Compliant. DB107S-G RoHS status is not specified in the provided data. All components carry REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited), confirming regulatory compliance for industrial applications.

Q: Which substitute offers the best supply chain security?

A: DB107S from MDD provides the highest inventory level (44,552 pieces) and Active product status, offering superior supply chain security for high-volume or long-term production requirements. DB107S-HF from Comchip and DF10S-E3/45 from Vishay are secondary options with substantial inventory and Active status.
