DF05 Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF05 is a single-phase bridge rectifier manufactured by SMC Diode Solutions, rated for 600V peak reverse voltage and 1A average rectified current. This component operates across a temperature range of -55°C to 150°C and is housed in a 4-EDIP through-hole package (DB-M supplier device package). The DF05 maintains Active product status with full RoHS3 compliance and REACH affected designation.

Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers offering equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF05 is determined by strict parametric equivalence across the following criteria:

Mandatory Matching Parameters:

• Voltage - Peak Reverse (Max): 600 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1 A
• Operating Temperature Range: -55°C to 150°C (TJ)
• Mounting Type: Through Hole
• Package / Case: 4-EDIP (0.321", 8.15mm)
• Diode Type: Single Phase
• Technology: Standard

Acceptable Variation:

• Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 600 V (within specification tolerance)
• Supplier Device Package designation: DB-M, DB-1, DB, DF, 4-DF (mechanical equivalents)

All substitute parts listed maintain identical electrical performance within the specified operating envelope and are mechanically compatible with the DF05 footprint and mounting requirements.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

DB105 (SMC Diode Solutions) and DF06-G (Comchip Technology) represent the preferred substitute options. Both maintain Active product status, full RoHS3 compliance, and identical electrical specifications to the DF05. DB105 is manufactured by the same supplier as the DF05, ensuring consistency in manufacturing processes and quality standards. DF06-G provides an alternative from an established manufacturer with equivalent parametric performance.

Secondary Substitute (Active Status, Compliance Variation):

DB105-BP (Micro Commercial Co) is electrically equivalent with Active product status and RoHS3 compliance. This part exhibits REACH Unaffected designation, which differs from the DF05 REACH Affected status. Current - Reverse Leakage specification is 10 µA @ 600 V, within acceptable tolerance limits.

DF06 (HY Electronic) is electrically equivalent with Active product status and RoHS3 compliance. REACH status is listed as Vendor Undefined. Current - Reverse Leakage specification is 10 µA @ 600 V, within acceptable tolerance limits.

Not Recommended for New Designs:

DB105-G (Comchip Technology) carries Obsolete product status. While electrically equivalent and RoHS3 compliant, obsolete designation indicates discontinued manufacturing and limited future availability. This part is suitable only for legacy system maintenance or repair applications where supply continuity is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can DB105-BP be used as a direct replacement for DF05?

A: Yes. DB105-BP meets all mandatory electrical parameters: 600V peak reverse voltage, 1A average rectified current, 1.1V forward voltage at 1A, and -55°C to 150°C operating temperature. The 4-EDIP package and through-hole mounting are identical. Current - Reverse Leakage of 10 µA @ 600 V is within acceptable specification tolerance. REACH Unaffected status differs from DF05, but this does not affect electrical or mechanical compatibility.

Q: What is the difference between DB105 and DF06?

A: Both parts are electrically identical with 600V, 1A ratings and 1.1V forward voltage. The primary differences are manufacturer (SMC Diode Solutions vs. HY Electronic) and supplier device package designation (DB-M vs. DF). Mechanical compatibility is maintained through the 4-EDIP package standard. Selection between these parts depends on supply availability and procurement preferences.

Q: Why is DB105-G listed as a substitute if it is Obsolete?

A: DB105-G maintains full electrical and mechanical equivalence to DF05 and is RoHS3 compliant. Obsolete status indicates the manufacturer has discontinued production. This part remains suitable for repair and maintenance of existing systems but should not be selected for new designs due to limited future availability and potential supply discontinuation.

Q: Are all substitute parts mechanically interchangeable with DF05?

A: Yes. All substitute parts use the 4-EDIP (0.321", 8.15mm) package with through-hole mounting. Supplier device package designations (DB-M, DB-1, DB, DF, 4-DF) represent manufacturer-specific labeling for the same physical package. PCB footprints and lead spacing are identical across all listed substitutes.

Q: What is the significance of Current - Reverse Leakage variation between 5 µA and 10 µA?

A: DF05 and DB105 specify 5 µA @ 600 V reverse leakage, while DB105-BP, DB105-G, DF06, and DF06-G specify 10 µA @ 600 V. Both values fall within standard bridge rectifier specifications and do not affect circuit functionality in typical applications. Selection between these parts depends on application requirements for leakage current performance and supply availability.

Q: Is RoHS3 compliance mandatory for all substitutes?

A: All listed substitute parts maintain RoHS3 compliance, matching the DF05 specification. This ensures consistency with environmental and regulatory requirements across all equivalent options.
