DL4005 Equivalent & Substitute Parts

Part Overview

The DL4005 is a general-purpose rectifier diode manufactured by Micro Commercial Co, rated for 600 V DC reverse voltage and 1 A average rectified current in a surface mount MELF package. This component is classified as obsolete, which necessitates identification of active equivalent and substitute parts for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package and mounting variations.

Substitute Part Grouping Explanation

Substitute parts for the DL4005 are grouped based on the following electrical and mechanical criteria:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 600 V minimum
Current - Average Rectified (Io): 1 A or greater
Mounting Type: Surface Mount
Package compatibility: DO-213AB MELF or equivalent surface mount package

Secondary Compatibility Factors:

Forward voltage (Vf) characteristics at rated current
Recovery speed classification (Standard or Fast Recovery)
Reverse leakage current specifications
Operating temperature range

Parts are classified into two substitution categories:

Category A - Direct Electrical Equivalents (600 V, 1 A): Parts meeting or exceeding the DL4005 electrical specifications with identical current ratings. These include 1N6482-E3/96, 1N6482-E3/97, 1N6482HE3/96, 1N6482HE3/97, GL41J/1, GL41JHE3/96, GL41JHE3/97, and 1N5618US.

Category B - Functional Equivalents with Current Derating (600 V, 500 mA): The 1N6663US operates at 500 mA average rectified current, representing a 50% current derating relative to the DL4005. This part is suitable for applications where the actual circuit current requirement does not exceed 500 mA.

Category C - Package Variant Equivalents (600 V, 1 A, D-5A Package): The 1N5618US and 1N5619US are rated for 600 V and 1 A but utilize the D-5A surface mount package instead of DO-213AB MELF, requiring PCB layout and footprint modification.

Engineering Selection Recommendations

For Direct Replacement with RoHS3 Compliance:

The Vishay SUPERECTIFIER® series parts (1N6482-E3/96, 1N6482-E3/97, 1N6482HE3/96, 1N6482HE3/97, GL41JHE3/96, GL41JHE3/97) provide electrical equivalence to the DL4005 with identical voltage, current, and forward voltage specifications. These parts are active products with ROHS3 compliance status and maintain the DO-213AB MELF package footprint. Operating temperature range extends to 175°C, exceeding the DL4005 specification of 150°C. Reverse leakage current is specified at 10 µA, compared to 5 µA for the DL4005, representing acceptable variance within standard rectifier diode tolerances.

For Direct Replacement without RoHS3 Compliance:

The GL41J/1 part number offers identical electrical specifications and package compatibility to the DL4005 while maintaining active product status. This part is suitable for applications where RoHS3 compliance is not required.

For Applications Accepting Package Modification:

The 1N5618US provides electrical equivalence with 600 V reverse voltage and 1 A average rectified current but requires PCB layout modification due to the D-5A package variant. This part is active and rated to 200°C junction temperature. The 1N5619US offers fast recovery characteristics (≤500 ns) with identical voltage and current ratings but utilizes the D-5A package and exhibits higher forward voltage (1.6 V @ 3 A).

For Current-Derated Applications:

The 1N6663US is suitable for circuits where the actual average rectified current does not exceed 500 mA. This part offers superior reverse leakage characteristics (50 nA @ 600 V) and fast recovery speed (≤500 ns) with active product status.

Frequently Asked Questions (FAQ)

Q: Can the 1N6482-E3/96 directly replace the DL4005 without PCB modification?

A: Yes. The 1N6482-E3/96 maintains identical electrical specifications (600 V, 1 A, 1.1 V forward voltage) and uses the same DO-213AB MELF package footprint as the DL4005. No PCB layout changes are required.

Q: What is the difference between 1N6482-E3/96 and 1N6482-E3/97?

A: Both parts are electrically identical with 600 V reverse voltage, 1 A average rectified current, and 1.1 V forward voltage. The suffix designations (-E3/96 and -E3/97) indicate different manufacturing date codes or tape reel configurations. Selection between these variants is based on procurement availability and inventory requirements.

Q: Why does the 1N5618US show higher forward voltage (1.3 V @ 3 A) compared to the DL4005 (1.1 V @ 1 A)?

A: Forward voltage specifications are measured at different current levels. The 1N5618US specification is measured at 3 A, while the DL4005 is measured at 1 A. Forward voltage increases with current in rectifier diodes. At the DL4005 operating point (1 A), the 1N5618US forward voltage would be lower than the specified 1.3 V value.

Q: Is the 1N6663US suitable as a direct replacement for the DL4005?

A: The 1N6663US is not a direct replacement due to current derating. It is rated for 500 mA average rectified current compared to the DL4005 rating of 1 A. This part is suitable only for applications where the actual circuit current does not exceed 500 mA.

Q: What is the impact of the higher reverse leakage current in the 1N6482 series (10 µA) compared to the DL4005 (5 µA)?

A: The 10 µA reverse leakage specification in the 1N6482 series represents a 5 µA increase from the DL4005. For most general-purpose rectifier applications, this variance is within acceptable operating margins and does not impact circuit functionality. Applications with stringent leakage requirements should evaluate specific circuit performance.

Q: Can the 1N5619US be used in place of the DL4005?

A: The 1N5619US provides electrical equivalence in voltage and current ratings but requires PCB footprint modification due to the D-5A package variant. Additionally, the 1N5619US exhibits fast recovery characteristics (≤500 ns) compared to the DL4005 standard recovery (>500 ns), and higher forward voltage (1.6 V @ 3 A). These differences are acceptable for most applications but should be verified against specific circuit requirements.

Q: What does ROHS3 compliance mean for the 1N6482 and GL41JHE3 series?

A: ROHS3 compliance indicates conformance to the Restriction of Hazardous Substances Directive 3, which restricts the use of specific hazardous materials in electrical and electronic equipment. Parts with ROHS3 compliance status are suitable for applications subject to environmental and regulatory requirements in regions enforcing these standards.

Q: Are there any thermal considerations when substituting the DL4005 with active alternatives?

A: The DL4005 is rated to 150°C junction temperature. Most active substitutes (1N6482 series, GL41 series, 1N5618US, 1N5619US, 1N6663US) are rated to 175°C or higher. This extended thermal rating provides additional design margin and does not present compatibility issues. Applications operating near the DL4005 thermal limit benefit from the higher ratings of substitute parts.

Q: What is the significance of the SUPERECTIFIER® designation on Vishay parts?

A: SUPERECTIFIER® is a Vishay product series designation indicating optimized rectifier diode performance characteristics. Parts bearing this designation meet Vishay's specifications for the SUPERECTIFIER® series but maintain standard rectifier diode functionality and compatibility with general-purpose applications.
