Engineering Selection Recommendations

Primary Substitutes (Active Status):

DF005S-E3/45 (Vishay General Semiconductor - Diodes Division) is the direct parametric equivalent with identical electrical specifications and Active product status. This part is suitable for new designs and ongoing production.

DF005S-T (Diodes Incorporated) meets all electrical requirements with extended lower operating temperature limit (-65°C vs. -55°C) and Active product status. This part is suitable for applications requiring enhanced low-temperature performance.

Secondary Substitutes (Limited Availability):

DF005S (onsemi) provides higher current rating (1.5 A vs. 1 A) and meets voltage and thermal specifications. However, this part is marked as Not For New Designs and should be used only when supply constraints require it.

DB101S-G and DF005S-G (Comchip Technology) are parametric equivalents but are classified as Obsolete. These parts should not be selected for new designs due to discontinued manufacturer support and limited availability.

All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and surface mount 4-SMD Gull Wing packaging compatibility with the original DF005SA-E3/45.

Frequently Asked Questions (FAQ)

Q: Can DF005S-E3/45 be used as a direct replacement for DF005SA-E3/45?

A: Yes. DF005S-E3/45 is a parametric equivalent with identical electrical ratings (50 V, 1 A, 1.1 V forward voltage) and operating temperature range (-55°C to 150°C). Both are manufactured by Vishay and maintain Active product status.

Q: What is the difference between DF005S-T and DF005SA-E3/45?

A: DF005S-T is manufactured by Diodes Incorporated and extends the lower operating temperature limit to -65°C (compared to -55°C). Electrical ratings are identical. DF005S-T is suitable for applications requiring enhanced low-temperature performance.

Q: Why is DF005S from onsemi listed as a substitute if it is marked "Not For New Designs"?

A: DF005S meets all electrical and mechanical requirements with a higher current rating (1.5 A). It is included for reference in supply chain scenarios where existing inventory must be utilized. New designs should prioritize Active status parts.

Q: Are Comchip Technology parts (DB101S-G, DF005S-G) suitable for new designs?

A: No. Both Comchip parts are classified as Obsolete. They are included for reference only and should not be selected for new designs due to discontinued manufacturer support.

Q: Is the 4-SMD Gull Wing package compatible across all substitute parts?

A: Yes. All listed substitute parts use the same 4-SMD Gull Wing surface mount package, ensuring mechanical and PCB layout compatibility with DF005SA-E3/45.

Q: What is the significance of the reverse leakage current difference (5 µA vs. 10 µA)?

A: DF005SA-E3/45 and DF005S-E3/45 specify 5 µA reverse leakage at 50 V. DF005S-T, DB101S-G, and DF005S-G specify 10 µA. Both values are within acceptable limits for standard bridge rectifier applications. Selection depends on application leakage requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the original DF005SA-E3/45 specifications.
