Engineering Selection Recommendations

Primary Substitutes (Full Electrical and Package Equivalence):

The parts 1N6479-E3/96, BYM10-100-E3/96, EGL41B-E3/96, and GL41B-E3/96 are all manufactured by Vishay General Semiconductor and provide complete electrical and mechanical compatibility with the DL4002-13. All four parts are rated for 100 V reverse voltage, 1 A average rectified current, and are packaged in the DO-213AB MELF surface mount configuration. These parts carry active product status and ROHS3 compliance certification, making them suitable for new designs and production environments with RoHS requirements.

Secondary Substitute (Current Rating Limitation):

The SMBD914E6327HTSA1 manufactured by Infineon Technologies is rated for 100 V reverse voltage but has a reduced average rectified current rating of 250 mA compared to the 1 A requirement of the DL4002-13. This part is housed in a TO-236-3 SOT-23-3 package, which differs from the DO-213AB MELF package of the original component. The SMBD914E6327HTSA1 carries Last Time Buy status, indicating limited future availability. This part is suitable only for applications where the 250 mA current rating is sufficient and where the SOT-23 package footprint is compatible with the circuit board design.

Compliance and Availability Considerations:

All Vishay substitute parts (1N6479-E3/96, BYM10-100-100-E3/96, EGL41B-E3/96, GL41B-E3/96) maintain active product status with confirmed inventory availability. These parts satisfy ROHS3 compliance requirements, addressing the non-compliant status of the discontinued DL4002-13. For applications requiring strict RoHS compliance in procurement and manufacturing, the Vishay alternatives are the preferred selection.

Frequently Asked Questions (FAQ)

Q: Can the 1N6479-E3/96 directly replace the DL4002-13 in existing designs?

A: Yes. The 1N6479-E3/96 meets all primary electrical specifications (100 V reverse voltage, 1 A average rectified current) and is packaged in the identical DO-213AB MELF surface mount configuration. No circuit board layout modifications are required for this substitution.

Q: What is the difference between the Vishay substitute parts?

A: All four Vishay parts (1N6479-E3/96, BYM10-100-E3/96, EGL41B-E3/96, GL41B-E3/96) share the same 100 V / 1 A electrical ratings and DO-213AB MELF package. Differences exist in recovery speed characteristics and reverse leakage specifications. The EGL41B-E3/96 offers fast recovery (≤500ns) with lower forward voltage (1 V @ 1 A), while the others provide standard recovery characteristics. Selection between these parts depends on specific circuit timing and power dissipation requirements.

Q: Why is the SMBD914E6327HTSA1 listed as a substitute if it has a lower current rating?

A: The SMBD914E6327HTSA1 is included in the substitute list because it meets the 100 V reverse voltage requirement and is electrically compatible with the DL4002-13 in applications where the circuit current demand does not exceed 250 mA. However, this part cannot be used as a direct replacement in designs requiring the full 1 A current capacity. Additionally, the SOT-23 package differs from the MELF package, requiring circuit board redesign for implementation.

Q: Are all substitute parts available in the same packaging formats?

A: The Vishay parts are available in different packaging formats: 1N6479-E3/96 and EGL41B-E3/96 are supplied in Tape & Reel (TR) format, while BYM10-100-E3/96 and GL41B-E3/96 are available in Cut Tape (CT) & Digi-Reel® format. The SMBD914E6327HTSA1 is supplied in Cut Tape (CT) format. Packaging format selection depends on production volume and assembly equipment compatibility.

Q: What is the operating temperature range difference between the DL4002-13 and its substitutes?

A: The DL4002-13 operates from -55°C to 150°C junction temperature. The Vishay substitute parts extend the upper temperature limit to 175°C, providing a wider operating range. The SMBD914E6327HTSA1 has a maximum junction temperature of 150°C, matching the original part. For applications operating near the upper temperature limits, the Vishay parts offer improved thermal margin.

Q: Is RoHS compliance a factor in selecting a substitute?

A: Yes. The DL4002-13 is RoHS non-compliant, while all listed substitute parts carry ROHS3 compliance certification. For procurement and manufacturing environments with RoHS requirements, the Vishay substitute parts are the appropriate selection. The SMBD914E6327HTSA1 also meets ROHS3 compliance but carries Last Time Buy status, limiting its suitability for long-term production use.

Q: Can I use the EGL41B-E3/96 in place of the DL4002-13 for improved performance?

A: The EGL41B-E3/96 offers performance improvements including faster recovery time (50 ns) and lower forward voltage (1 V @ 1 A) compared to the DL4002-13. These characteristics reduce power dissipation and improve switching performance in rectifier circuits. The EGL41B-E3/96 is electrically and mechanically compatible with the DL4002-13 and can be used as a direct replacement with potential circuit performance benefits.
