Substitute Part Grouping Explanation

Substitution of the DF15005SP-G is determined by equivalence across the following critical parameters: single-phase diode type, standard technology classification, 50 V peak reverse voltage rating, 1.5 A average rectified current capacity, 1.1 V maximum forward voltage at 1.5 A, surface mount mounting type, and 4-SMD Gull Wing package configuration. All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility within the original application circuit.

The substitute parts are grouped into two categories: manufacturer-recommended substitutes from Comchip Technology and parametric equivalents from alternative manufacturers (Taiwan Semiconductor Corporation and Vishay General Semiconductor - Diodes Division). All listed substitutes are active products with current availability.

Engineering Selection Recommendations

Primary Recommendation: DF15005S-G

The DF15005S-G from Comchip Technology is the manufacturer-recommended direct substitute for the obsolete DF15005SP-G. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. Selection of this part eliminates supply chain risk associated with obsolete components.

Alternative Selections: DBLS151G C1G and DBLS151GHC1G

The DBLS151G C1G and DBLS151GHC1G from Taiwan Semiconductor Corporation provide parametric equivalence with identical voltage and current ratings. The DBLS151GHC1G variant includes AEC-Q101 automotive qualification, suitable for applications requiring automotive-grade components. Both parts demonstrate lower reverse leakage current (2 µA @ 50 V) compared to the original specification.

Secondary Alternatives: DF15005S-E3/45 and DFL15005S-E3/45

The DF15005S-E3/45 and DFL15005S-E3/45 from Vishay General Semiconductor - Diodes Division maintain full electrical and mechanical compatibility. Both parts are ROHS3 compliant and active products. The DFL15005S-E3/45 exhibits higher reverse leakage current (400 µA @ 30 V) and should be evaluated for applications with stringent leakage specifications.

Frequently Asked Questions (FAQ)

Q: Can DF15005S-G be used as a direct replacement for DF15005SP-G?

A: Yes. The DF15005S-G maintains identical electrical specifications (50 V peak reverse voltage, 1.5 A average rectified current, 1.1 V forward voltage) and package configuration (4-SMD, Gull Wing). The primary difference is product status: DF15005S-G is active while DF15005SP-G is obsolete.

Q: What is the difference between the Comchip and Taiwan Semiconductor alternatives?

A: Both DF15005S-G and DBLS151G C1G meet the core electrical requirements. The DBLS151G C1G exhibits lower reverse leakage current (2 µA @ 50 V versus 5 µA @ 50 V). The DBLS151GHC1G variant adds AEC-Q101 automotive qualification for applications requiring automotive-grade certification.

Q: Are all substitute parts in the same package?

A: Yes. All listed substitute parts use the 4-SMD, Gull Wing package configuration, ensuring mechanical compatibility with the original DF15005SP-G footprint.

Q: What compliance certifications apply to the substitute parts?

A: All active substitute parts (DF15005S-G, DBLS151G C1G, DBLS151GHC1G, DF15005S-E3/45, DFL15005S-E3/45) are ROHS3 compliant. The DBLS151GHC1G additionally carries AEC-Q101 automotive qualification.

Q: How do reverse leakage specifications differ among substitutes?

A: The original DF15005SP-G specifies 5 µA @ 50 V. The DBLS variants specify 2 µA @ 50 V (lower leakage). The DF15005S-E3/45 specifies 5 µA @ 1000 V. The DFL15005S-E3/45 specifies 400 µA @ 30 V (higher leakage). Selection should account for application-specific leakage requirements.

Q: What is the moisture sensitivity level for substitute parts?

A: All active substitute parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling.
