DL4004-13-F Equivalent & Substitute Parts

Part Overview

The DL4004-13-F is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 400 V DC reverse voltage and 1 A average rectified current in a surface mount MELF (DO-213AB) package. This part is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts are selected based on matching or exceeding electrical performance parameters while maintaining compatible mechanical packaging and thermal characteristics.

Substitute Part Grouping Explanation

Substitute parts for the DL4004-13-F are grouped into two categories based on electrical and mechanical compatibility:

Category 1: Direct Electrical and Package Equivalents (400 V, 1 A, DO-213AB MELF)

These parts maintain the same reverse voltage rating (400 V), current rating (1 A), and mechanical package (DO-213AB MELF). Substitution is based on matching these three core parameters: Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io), and Package / Case. Parts in this category include GL41G-E3/96 and EGL41G/1.

Category 2: Electrical Equivalents with Package Variation (400 V, 1 A, Alternative Surface Mount Packages)

These parts maintain the same reverse voltage rating (400 V) and current rating (1 A) but use alternative surface mount packages (SMA or D-5A). Substitution is based on matching voltage and current parameters while accepting package differences. Parts in this category include 1N5616US, 1N5617US, and S1M-13-F (which exceeds voltage rating at 1000 V).

Category 3: Partial Electrical Equivalents (400 V, Reduced Current Rating)

The part 1N6662US maintains the 400 V reverse voltage rating but has a reduced current rating of 500 mA (half the original 1 A specification). This part is suitable only for applications where the lower current rating is acceptable.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalents)

GL41G-E3/96 and EGL41G/1 are the preferred substitutes for the DL4004-13-F. Both are manufactured by Vishay and maintain the identical 400 V / 1 A electrical specification with DO-213AB MELF packaging. Both parts are active products with ROHS3 compliance. GL41G-E3/96 matches the original standard recovery speed characteristic, while EGL41G/1 offers improved fast recovery performance (≤500ns) with lower reverse recovery time (50 ns). Both parts support extended operating temperature ranges (-65°C to 175°C) compared to the original part (-55°C to 150°C).

Secondary Substitutes (Electrical Equivalents with Package Variation)

1N5616US and 1N5617US are active Microchip Technology products that maintain 400 V / 1 A electrical specifications but use SQ-MELF (D-5A) packaging instead of DO-213AB MELF. These parts are suitable for applications where package footprint differences are acceptable. 1N5616US provides standard recovery characteristics, while 1N5617US offers fast recovery performance. Both support extended temperature ranges (-65°C to 200°C or -65°C to 175°C). Note: These parts are RoHS non-compliant.

Higher Voltage Alternative

S1M-13-F is an active Diodes Incorporated product with elevated 1000 V reverse voltage rating and 1 A current rating. This part uses DO-214AC SMA packaging. S1M-13-F is suitable for applications requiring higher voltage margin or where SMA package compatibility exists. ROHS3 compliance is maintained.

Reduced Current Alternative

1N6662US is an active Microchip Technology product rated for 400 V / 500 mA. This part is suitable only for applications where the reduced 500 mA current rating meets circuit requirements. RoHS non-compliant.

Frequently Asked Questions (FAQ)

Q: Can GL41G-E3/96 directly replace DL4004-13-F without circuit modification?

A: Yes. GL41G-E3/96 maintains identical electrical specifications (400 V, 1 A) and mechanical packaging (DO-213AB MELF). Both parts are surface mount components with matching footprints. No circuit modification is required.

Q: What is the difference between standard recovery and fast recovery diodes in these substitutes?

A: Recovery speed refers to the time required for the diode to transition from conducting to blocking state. Standard recovery (>500ns) is characteristic of DL4004-13-F, GL41G-E3/96, and 1N5616US. Fast recovery (≤500ns) is offered by EGL41G/1 and 1N5617US. Fast recovery diodes exhibit lower reverse recovery time, reducing switching losses in high-frequency applications. Selection depends on circuit operating frequency and switching requirements.

Q: Why is S1M-13-F listed as a substitute if it has 1000 V rating instead of 400 V?

A: S1M-13-F is listed as a substitute because it maintains the 1 A current rating and surface mount technology. The higher 1000 V rating provides additional voltage margin and is electrically compatible with 400 V applications. However, S1M-13-F uses DO-214AC SMA packaging instead of DO-213AB MELF, requiring PCB layout verification. This part is suitable for designs where package change is acceptable.

Q: Can 1N6662US be used in place of DL4004-13-F?

A: 1N6662US is not a direct substitute. While it maintains the 400 V reverse voltage rating, the current rating is reduced to 500 mA (half the original 1 A specification). 1N6662US is suitable only for applications where the circuit current requirement does not exceed 500 mA. Verify circuit current specifications before selection.

Q: What is the impact of RoHS compliance status on part selection?

A: DL4004-13-F, GL41G-E3/96, EGL41G/1, and S1M-13-F are ROHS3 compliant. 1N5616US, 1N5617US, and 1N6662US are RoHS non-compliant. For applications subject to RoHS regulations or customer requirements, select only ROHS3 compliant parts. For legacy or non-regulated applications, RoHS non-compliant parts are acceptable.

Q: Are there thermal performance differences between substitutes?

A: Yes. DL4004-13-F operates from -55°C to 150°C. GL41G-E3/96 and EGL41G/1 extend the upper limit to 175°C. 1N5616US supports -65°C to 200°C, offering the widest temperature range. 1N5617US and 1N6662US support -65°C to 175°C. For applications requiring extended temperature operation, select parts with appropriate Tj ratings.

Q: What packaging considerations apply when substituting with 1N5616US or 1N5617US?

A: 1N5616US and 1N5617US use SQ-MELF (D-5A) packaging instead of DO-213AB MELF. While both are surface mount MELF variants, the physical dimensions and PCB footprints differ. Verify PCB layout compatibility and reflow profile suitability before design implementation. Consult manufacturer datasheets for precise package dimensions.
