Engineering Selection Recommendations

For RoHS3 Compliant Applications: SD103C-TAP and SD103C-TR from Vishay are the only substitutes with active product status and RoHS3 compliance. Both parts support 20V reverse voltage in DO-35 package with 200mA current rating, exceeding the original 35mA specification. SD103C-TAP is supplied in Tape & Box packaging; SD103C-TR is supplied in Cut Tape packaging.

For Non-RoHS Applications with Extended Temperature Range: 1N5712, 1N5712-1, 1N6857-1, DSB2810, and DSB5712 maintain the -65°C to 150°C operating range compatible with the original part's lower temperature bound. These parts are active and available in volume. Current ratings range from 75mA to 150mA, all exceeding the original 35mA specification.

For Higher Current Applications: DSB0.2A20, DSB0.2A40, and DSB0.5A20 support 200mA to 500mA current ratings with 20V reverse voltage in DO-35 package. Operating temperature maximum is -65°C to 125°C. These parts are suitable for applications requiring higher current handling than the original specification.

Compliance Considerations: All substitute parts maintain EAR99 ECCN classification and REACH Unaffected status. Moisture sensitivity level is 1 (Unlimited) across all substitutes. The original 5082-2810 is RoHS non-compliant; only Vishay SD103C variants offer RoHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with a higher current rating than the original 5082-2810?

A: Yes. The 5082-2810 is rated for 35mA maximum current. All listed substitutes have equal or higher current ratings. Higher current ratings do not create compatibility issues in applications designed for the original part, as the diode will operate within its safe operating region.

Q: What is the difference between SD103C-TAP and SD103C-TR?

A: Both parts are electrically identical Vishay SD103C Schottky diodes rated for 20V with 200mA current in DO-35 package. The difference is packaging: SD103C-TAP is supplied in Tape & Box format, while SD103C-TR is supplied in Cut Tape format. Select based on your procurement and assembly requirements.

Q: Are the Microchip DSB series parts direct replacements?

A: Yes. All DSB series parts (DSB0.2A20, DSB0.2A40, DSB0.5A20, DSB2810, DSB5712) are Schottky diodes rated for 20V reverse voltage in DO-35 package with active product status. Current ratings vary from 75mA to 500mA. Select the DSB variant matching your application's current requirement.

Q: Why is the original 5082-2810 obsolete?

A: The 5082-2810 is classified as obsolete by Broadcom Limited. Substitute parts from active manufacturers (Vishay, Microchip) provide equivalent electrical performance and are currently in production with ongoing availability.

Q: Do all substitutes support the original operating temperature range of -65°C to 200°C?

A: No. The original 5082-2810 supports -65°C to 200°C junction temperature. Substitute parts support lower maximum temperatures: Vishay SD103C variants support -65°C to 125°C; Microchip 1N5712 and 1N6857-1 variants support -65°C to 150°C; Microchip DSB0.2 and DSB0.5 variants support -65°C to 125°C. Verify your application's maximum operating temperature requirement before selection.

Q: Which substitute offers the best RoHS compliance?

A: Vishay SD103C-TAP and SD103C-TR are RoHS3 compliant. All other substitutes are RoHS non-compliant, matching the original 5082-2810 compliance status.

Q: Can I mix different substitute parts in the same design?

A: All listed substitutes are electrically compatible as Schottky diodes with 20V rating in DO-35 package. However, maintain consistency within a single design to simplify procurement, testing, and documentation. If mixing is necessary, verify that forward voltage and leakage current specifications are acceptable for your circuit topology.
