DF06 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF06 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 800V peak reverse voltage and 1A average rectified current. This component is designed for through-hole mounting applications requiring standard bridge rectification in industrial and consumer electronics. The part is currently in active production status with 1120 units in stock.

Substitute parts become necessary when the primary part number is unavailable, when supply chain constraints limit access to the original manufacturer's inventory, or when design flexibility permits the use of functionally equivalent components from alternative manufacturers. The DF06 has documented parametric equivalents that maintain electrical and mechanical compatibility while offering alternative sourcing options.

Substitute Part Grouping Explanation

Substitution of the DF06 bridge rectifier is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Voltage - Peak Reverse (Max): 800 V
• Current - Average Rectified (Io): 1 A
• Diode Type: Single Phase
• Technology: Standard

Mechanical Equivalence Criteria:

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

Compliance Equivalence Criteria:

• RoHS3 Compliant status
• ECCN: EAR99
• HTSUS: 8541.10.0080

The DB106-BP manufactured by Micro Commercial Co meets all electrical, mechanical, and compliance requirements for direct substitution with the DF06. Both components share identical voltage and current ratings, operate across the same temperature range, utilize the same through-hole package footprint, and maintain equivalent forward voltage characteristics. Minor variations in reverse leakage current (5 µA for DF06 versus 10 µA for DB106-BP) remain within acceptable operational tolerances for standard bridge rectifier applications.

Parameter Comparison

Engineering Selection Recommendations

DF06 (SMC Diode Solutions) is the primary component specification. This part maintains active production status with established supply availability (1120 units in stock). The DF06 carries ROHS3 compliance and is classified as REACH Affected, indicating full regulatory documentation for restricted substance management.

DB106-BP (Micro Commercial Co) serves as the parametric equivalent substitute. This component is also in active production with higher inventory availability (5744 units in stock). The DB106-BP maintains ROHS3 compliance but is classified as REACH Unaffected, which may present advantages in supply chain scenarios where REACH documentation requirements create procurement delays. Both components share identical electrical ratings, thermal operating ranges, and package specifications.

Selection between DF06 and DB106-BP should be based on:

• Inventory availability and lead time requirements
• Established supplier relationships and qualification history
• REACH compliance documentation requirements for the end application
• Cost considerations within procurement parameters

Both components are suitable for direct substitution in 800V, 1A single-phase bridge rectifier applications without circuit redesign or thermal re-evaluation.

Frequently Asked Questions (FAQ)

Q: Can DB106-BP replace DF06 in existing circuit designs without modification?

A: Yes. The DB106-BP is a parametric equivalent with identical voltage ratings (800V), current ratings (1A), forward voltage characteristics (1.1V @ 1A), and package footprint (4-EDIP, 0.321", 8.15mm). No circuit modifications are required for direct substitution.

Q: What is the significance of the reverse leakage current difference between DF06 (5 µA) and DB106-BP (10 µA)?

A: Both components operate at 800V reverse voltage with leakage currents well below typical circuit requirements for standard bridge rectifier applications. The 5 µA specification of the DF06 represents lower leakage, but the 10 µA specification of the DB106-BP remains within acceptable operational parameters for equivalent functionality.

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

A: Yes. Both the DF06 and DB106-BP operate across the identical temperature range of -55°C to 150°C (TJ), ensuring equivalent thermal performance in all environmental conditions.

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

A: Both components are ROHS3 compliant and share the same ECCN (EAR99) and HTSUS (8541.10.0080) classifications. The DF06 is REACH Affected while the DB106-BP is REACH Unaffected; this distinction affects documentation requirements but not electrical or mechanical compatibility.

Q: Is the through-hole package footprint identical between DF06 and DB106-BP?

A: Yes. Both components use the 4-EDIP package with dimensions of 0.321" (8.15mm), ensuring identical PCB mounting compatibility and no layout modifications required.

Q: What inventory considerations should influence part selection?

A: The DB106-BP currently has higher inventory availability (5744 units) compared to the DF06 (1120 units). For applications with extended production runs or time-sensitive procurement, the DB106-BP may offer supply chain advantages.
