DF02 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF02 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 100V peak reverse voltage and 1A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in the 100V/1A performance class. The DF02 maintains active product status and is suitable for new designs.

Equivalent and substitute parts are identified based on matching electrical performance parameters, mechanical compatibility, and thermal operating range. Substitutes enable design flexibility when primary components face supply constraints or when alternative manufacturers' components meet identical functional requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF02 is determined by the following critical parameters:

Electrical Performance Matching:

• Voltage - Peak Reverse (Max): 100V
• Current - Average Rectified (Io): 1A
• Voltage - Forward (Vf) (Max) @ If: 1.1V @ 1A
• Diode Type: Single Phase
• Technology: Standard

Mechanical & Environmental Compatibility:

• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Operating Temperature Range: -55°C to 150°C (TJ)

Compliance & Regulatory:

Engineering Selection Recommendations

DF02 (SMC Diode Solutions) - Primary Selection

The DF02 is the recommended component for new designs. It maintains active product status, ensuring long-term availability and manufacturer support. The component is fully RoHS3 compliant and carries unlimited moisture sensitivity classification, suitable for standard manufacturing environments.

DB102-BP (Micro Commercial Co) - Substitute Selection

The DB102-BP is a valid electrical and mechanical substitute where supply of the DF02 is constrained. All critical electrical parameters match the DF02 specification. The reverse leakage current specification (10 µA @ 100V) is slightly higher than the DF02 (5 µA @ 100V) but remains within acceptable tolerance for standard bridge rectifier applications.

The DB102-BP carries a "Not For New Designs" product status designation. This classification indicates the manufacturer is not recommending this part for new product development. Existing designs currently using the DB102-BP may continue to source this component, but new designs should prioritize the DF02.

Both components are RoHS3 compliant and carry MSL 1 (Unlimited) classification, ensuring compatibility with standard through-hole assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the DB102-BP directly replace the DF02 in existing circuit designs?

A: Yes. The DB102-BP matches all critical electrical parameters (100V peak reverse voltage, 1A average rectified current, 1.1V forward voltage) and mechanical specifications (4-EDIP through-hole package, identical pin spacing). The reverse leakage current difference (10 µA versus 5 µA) does not affect standard bridge rectifier functionality.

Q: Why is the DB102-BP marked "Not For New Designs"?

A: The "Not For New Designs" status indicates the manufacturer (Micro Commercial Co) is not actively promoting this component for new product development. This is a manufacturer lifecycle designation and does not reflect electrical or mechanical deficiency. New designs should specify the DF02 to ensure long-term availability and manufacturer support.

Q: Are the package dimensions identical between DF02 and DB102-BP?

A: Yes. Both components use the 4-EDIP package with dimensions of 0.321 inches (8.15mm). Pin spacing and through-hole mounting compatibility are identical, enabling direct PCB footprint compatibility.

Q: What is the significance of the reverse leakage current difference?

A: The DF02 specifies 5 µA reverse leakage at 100V, while the DB102-BP specifies 10 µA at 100V. This difference is within normal manufacturing tolerance for standard bridge rectifiers and does not impact circuit performance in typical rectification applications. Both values represent low leakage operation suitable for power supply and general rectification use.

Q: Are both components suitable for the same operating temperature range?

A: Yes. Both the DF02 and DB102-BP operate across the identical temperature range of -55°C to 150°C (junction temperature). Thermal performance and reliability are equivalent across this range.

Q: Do both components meet the same regulatory compliance standards?

A: Yes. Both the DF02 and DB102-BP are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are suitable for standard manufacturing environments without special handling requirements.
