Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF005S2 is determined by strict equivalence across the following critical electrical and mechanical parameters:

• Diode Type: Single Phase bridge rectifier configuration
• Voltage Rating: 50V peak reverse voltage (Vrrm)
• Current Rating: 2A average rectified current (Io)
• Forward Voltage: 1.1V maximum at 2A
• Reverse Leakage: Acceptable within specified limits at rated voltage
• Package Type: 4-SMD, Gull Wing surface mount configuration
• Temperature Range: -55°C to 150°C junction temperature capability
• Compliance: ROHS3 and MSL Level 1 requirements

The DB201S from SMC Diode Solutions meets all these criteria and is classified as a parametric equivalent. Both components share identical electrical ratings, thermal specifications, and surface mount package geometry, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The DB201S is a direct parametric equivalent to the DF005S2 and is suitable for substitution in applications requiring a 50V, 2A single-phase bridge rectifier in 4-SDIP surface mount packaging. The DB201S maintains active product status with SMC Diode Solutions, ensuring ongoing availability and supply chain continuity compared to the obsolete DF005S2.

Both components satisfy ROHS3 compliance and MSL Level 1 requirements. The reverse leakage current of the DB201S (5 µA @ 50 V) is within acceptable tolerance relative to the DF005S2 specification (3 µA @ 50 V), with no functional impact on circuit performance. Electrical characteristics, thermal ratings, and mechanical package dimensions are identical, enabling direct PCB footprint compatibility and circuit-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the DB201S replace the DF005S2 in existing designs?

A: Yes. The DB201S is a parametric equivalent with identical voltage, current, and temperature ratings. The 4-SMD, Gull Wing package geometry is identical, ensuring PCB footprint compatibility. No circuit redesign is required.

Q: What is the difference in reverse leakage current between these parts?

A: The DF005S2 specifies 3 µA maximum reverse leakage at 50V, while the DB201S specifies 5 µA at the same conditions. This 2 µA difference is within normal manufacturing tolerance for bridge rectifier technology and does not affect circuit functionality in standard rectification applications.

Q: Why is the DF005S2 marked as obsolete?

A: The DF005S2 is classified as obsolete by onsemi. The DB201S from SMC Diode Solutions provides equivalent electrical and mechanical specifications with active product status, ensuring long-term availability and supply chain support.

Q: Are there any compliance differences between these parts?

A: Both components are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings. Compliance certifications are equivalent, and both are suitable for applications requiring these standards.

Q: What packaging formats are available for these parts?

A: The DF005S2 is supplied in Cut Tape (CT) and Digi-Reel format. The DB201S is supplied in Tape & Reel (TR) format. Both use identical 4-SDIP surface mount package geometry. Packaging format selection depends on procurement and assembly requirements rather than electrical or mechanical compatibility.
