DL4005-TP Equivalent & Substitute Parts

Part Overview

The DL4005-TP is a general-purpose rectifier diode rated for 600 V DC reverse voltage and 1 A average rectified current, packaged in a Surface Mount MELF (DO-213AB) configuration. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status, equivalent substitute parts with active product status are necessary for new designs and ongoing production requirements. Substitute diodes must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating different package formats where applicable.

Voltage - Forward (Vf) (Max): Must not exceed application circuit limits
Current - Reverse Leakage @ Vr: Lower values indicate superior performance
Recovery Speed: Standard or faster recovery characteristics acceptable

Mechanical Compatibility Requirements:

Mounting Type: Surface Mount (all substitutes)
Package / Case: DO-213AB (MELF) preferred for direct replacement; DO-214AC (SMA) and D-5A (SQ-MELF) acceptable with PCB layout modification

Engineering Selection Recommendations

Primary Substitute (Package-Compatible):

The RGL41J/1 (Vishay General Semiconductor) is the preferred substitute for direct replacement of the DL4005-TP. Both components utilize the DO-213AB (MELF) package, eliminating PCB layout modifications. The RGL41J/1 maintains identical voltage and current ratings (600 V, 1 A), operates across a compatible temperature range (-65°C ~ 175°C), and features active product status ensuring long-term availability. The RGL41J/1 exhibits superior reverse leakage characteristics (5 µA @ 600 V, matching the original) and faster recovery speed (≤500ns). However, the RGL41J/1 carries RoHS non-compliant status, which may impact applications requiring ROHS3 compliance.

Secondary Substitute (RoHS3 Compliant, Package Modification Required):

The GS1J-LTP (Micro Commercial Co) is the only active substitute maintaining ROHS3 compliance. This component matches the 600 V / 1 A electrical specifications and operates within the -55°C ~ 150°C temperature range. The GS1J-LTP is packaged in DO-214AC (SMA) format, requiring PCB footprint modification from the original MELF package. Forward voltage performance is superior (1 V @ 1 A versus 1.1 V @ 1 A), though reverse leakage is slightly elevated (10 µA @ 600 V). The GS1J-LTP is suitable for new designs prioritizing regulatory compliance.

Functional Equivalents (Current-Rated Substitutes):

The 1N5619US and 1N5618US (Microchip Technology) provide 1 A current ratings with enhanced temperature ranges (-65°C ~ 175°C and -65°C ~ 200°C respectively) and superior reverse leakage performance (500 nA @ 600 V). Both utilize D-5A (SQ-MELF) packaging, requiring PCB modification. The 1N5619US features fast recovery characteristics (250 ns), while the 1N5618US maintains standard recovery speed. Both carry RoHS non-compliant status.

Current-Reduced Substitute:

The 1N6663US (Microchip Technology) is rated for 500 mA average rectified current, below the 1 A requirement of the DL4005-TP. This component is suitable only for applications where actual circuit current demand does not exceed 500 mA. The 1N6663US offers superior reverse leakage (50 nA @ 600 V) and fast recovery characteristics (≤500ns) but carries RoHS non-compliant status.

Frequently Asked Questions (FAQ)

Q: Can the GS1J-LTP replace the DL4005-TP without PCB modification?

A: No. The GS1J-LTP uses DO-214AC (SMA) packaging while the DL4005-TP uses DO-213AB (MELF) packaging. These packages have different footprints and pin configurations, requiring PCB layout modification. However, electrical specifications are compatible.

Q: Is the RGL41J/1 a direct pin-for-pin replacement?

A: Yes. The RGL41J/1 uses the same DO-213AB (MELF) package as the DL4005-TP, enabling direct PCB replacement without layout modification. Electrical specifications are compatible across all critical parameters.

Q: Why is the 1N6663US listed as a substitute if it has only 500 mA current rating?

A: The 1N6663US is a functional equivalent suitable only for applications where the actual circuit current does not exceed 500 mA. It is not a universal substitute for all DL4005-TP applications. Circuit analysis is required to confirm current demand before selecting this component.

Q: What is the impact of forward voltage differences between substitutes?

A: Forward voltage differences affect power dissipation and circuit performance. The DL4005-TP specifies 1.1 V @ 1 A. Substitutes with lower forward voltage (GS1J-LTP at 1 V @ 1 A) reduce power loss, while those with higher forward voltage (1N5619US at 1.6 V @ 3 A) increase dissipation. Circuit thermal analysis may be required for high-current applications.

Q: Are all substitutes suitable for new product designs?

A: No. The GS1J-LTP is the only substitute maintaining ROHS3 compliance, making it the preferred choice for new designs subject to regulatory requirements. Other substitutes carry RoHS non-compliant status and are suitable for legacy product support or applications without compliance mandates.

Q: What is the significance of reverse recovery time (trr) differences?

A: Reverse recovery time affects switching performance in high-frequency applications. The DL4005-TP specifies standard recovery (>500ns). Substitutes with faster recovery (1N5619US at 250 ns, RGL41J/1 at 250 ns) reduce switching losses and electromagnetic interference in switching circuits. Standard recovery substitutes (1N5618US, GS1J-LTP) maintain compatibility with the original specification.

Q: Can substitutes with extended temperature ranges replace the DL4005-TP in all applications?

A: Extended temperature ranges (-65°C ~ 200°C for 1N5618US) provide additional operational margin but do not alter electrical compatibility. Selection depends on application thermal requirements. The DL4005-TP specifies -65°C ~ 150°C; substitutes with higher upper limits offer design flexibility for high-temperature environments.

Q: What is the impact of reverse leakage current differences?

A: Reverse leakage affects circuit performance in high-impedance applications and standby power consumption. The DL4005-TP specifies 5 µA @ 600 V. Substitutes with lower leakage (1N6663US at 50 nA, 1N5619US at 500 nA) reduce standby current and improve circuit efficiency. Higher leakage (GS1J-LTP at 10 µA) has minimal impact in most applications.

Q: Is inventory availability a factor in substitute selection?

A: Yes. Current inventory levels are: GS1J-LTP (1,318 pcs), 1N5618US (799 pcs), 1N5619US (946 pcs), 1N6663US (941 pcs), and RGL41J/1 (835 pcs). All substitutes maintain adequate stock for production requirements. Selection should prioritize long-term availability and product status (active versus obsolete).
