DL4003-13-F Equivalent & Substitute Parts

Part Overview

The DL4003-13-F is a general-purpose rectifier diode manufactured by Diodes Incorporated, rated for 200 V DC reverse voltage and 1 A average rectified current in a surface mount MELF package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain electrical performance within the specified voltage and current ratings while accommodating the surface mount package format.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DL4003-13-F are selected based on the following critical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) (Max): 200 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower at rated current
• Speed: Standard Recovery >500ns, > 200mA (Io)

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: DO-213AB or MELF equivalent

Compliance Criteria:

• RoHS3 Compliant status preferred for new designs
• Operating Temperature Range: -55°C minimum to 150°C maximum

The substitute parts BYM10-200-E3/96, BYM10-200-E3/97, and 1N5614US meet or exceed these electrical and mechanical requirements. BYM10-200-E3/96 and BYM10-200-E3/97 are functionally equivalent Vishay SUPERECTIFIER® diodes with active product status. The 1N5614US is a Microchip Technology alternative with extended temperature range capability.

Parameter Comparison

Engineering Selection Recommendations

BYM10-200-E3/96 and BYM10-200-E3/97 (Preferred Substitutes)

Both Vishay SUPERECTIFIER® parts are direct functional equivalents with active product status. These diodes maintain identical electrical specifications at the primary operating point (1.1 V @ 1 A forward voltage) and meet all mechanical compatibility requirements. The BYM10 series offers improved reverse leakage characteristics (10 µA vs. 5 µA) and reduced capacitance (8pF vs. 15pF), resulting in superior high-frequency performance. Extended operating temperature range (-65°C to 175°C) provides additional design margin. Both variants are ROHS3 compliant and available in Tape & Reel packaging for production environments. BYM10-200-E3/96 and BYM10-200-E3/97 differ only in packaging configuration and are interchangeable from an electrical standpoint.

1N5614US (Alternative Substitute)

The Microchip Technology 1N5614US provides equivalent voltage and current ratings with superior reverse leakage performance (500 nA @ 200 V). This part features the widest operating temperature range (-65°C to 200°C) and is suitable for extended-temperature applications. However, the 1N5614US is RoHS non-compliant and carries forward voltage specification at 3 A rather than 1 A, requiring circuit-level evaluation for applications with strict compliance requirements. The D-5A package is mechanically compatible with MELF footprints.

Compliance Considerations

For applications requiring ROHS3 compliance, BYM10-200-E3/96 or BYM10-200-E3/97 are the appropriate selections. The 1N5614US is suitable only for applications where RoHS non-compliance is acceptable.

Frequently Asked Questions (FAQ)

Q: Can BYM10-200-E3/96 and BYM10-200-E3/97 be used interchangeably with DL4003-13-F?

A: Yes. Both Vishay parts meet or exceed all electrical specifications of the DL4003-13-F, including voltage rating (200 V), current rating (1 A), forward voltage (1.1 V @ 1 A), and recovery speed. Both are surface mount components in DO-213AB MELF packages with identical pinouts and footprints.

Q: What is the difference between BYM10-200-E3/96 and BYM10-200-E3/97?

A: Both parts are electrically identical. The difference is in packaging format: BYM10-200-E3/96 and BYM10-200-E3/97 are supplied in Tape & Reel configuration. Selection between these variants depends on procurement and assembly requirements rather than electrical performance.

Q: Is the 1N5614US a suitable replacement for the DL4003-13-F?

A: The 1N5614US meets the core electrical requirements (200 V, 1 A, standard recovery speed) and is mechanically compatible. However, it is RoHS non-compliant, which may restrict its use in regulated applications. The forward voltage specification is provided at 3 A rather than 1 A, requiring circuit analysis to confirm suitability for 1 A operation.

Q: What are the key differences in reverse leakage between these parts?

A: The DL4003-13-F specifies 5 µA @ 200 V reverse leakage. The BYM10-200-E3/96 and BYM10-200-E3/97 specify 10 µA @ 200 V. The 1N5614US specifies 500 nA @ 200 V, representing significantly lower leakage. Lower reverse leakage improves efficiency in low-current applications and reduces power dissipation.

Q: Are there temperature range limitations when substituting these parts?

A: The DL4003-13-F operates from -55°C to 150°C. The BYM10 series extends this to -65°C to 175°C, and the 1N5614US extends to -65°C to 200°C. All substitutes accommodate the original temperature range, with extended capability available if required by application.

Q: What packaging considerations apply to these substitutes?

A: All three substitute parts are surface mount components compatible with MELF footprints. The BYM10-200-E3/96 and BYM10-200-E3/97 are supplied in Tape & Reel format suitable for automated assembly. The 1N5614US is supplied in Bulk format. PCB footprint compatibility is maintained across all parts.

Q: Which substitute is recommended for new designs?

A: BYM10-200-E3/96 or BYM10-200-E3/97 are recommended for new designs due to active product status, ROHS3 compliance, and proven availability. These parts provide the best balance of electrical performance, regulatory compliance, and supply chain stability.
