The substitute parts DF1501S-E3/45 and DFL1501S-E3/45, both manufactured by Vishay General Semiconductor - Diodes Division, meet all specified electrical and mechanical parameters. These components are functionally interchangeable with the DBLS152G C1G in applications requiring single-phase bridge rectification at 100 V and 1.5 A ratings.

Parameter Comparison

Engineering Selection Recommendations

All three components—DBLS152G C1G, DF1501S-E3/45, and DFL1501S-E3/45—are active products with identical electrical ratings and mechanical specifications. Selection between these parts is based on availability, supply chain considerations, and manufacturer preference.

Compliance Status: All substitute parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. Moisture sensitivity level 1 (unlimited) indicates no special storage or handling requirements for any of these components.

Electrical Equivalence: The substitute parts from Vishay General Semiconductor - Diodes Division operate within the same voltage and current parameters as the main part. The reverse leakage current specification (5 µA versus 2 µA) remains within acceptable tolerances for standard bridge rectifier applications and does not impact functional compatibility.

Mechanical Compatibility: All parts utilize identical 4-SMD, Gull Wing surface mount packaging, ensuring direct PCB footprint compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can DF1501S-E3/45 or DFL1501S-E3/45 be used as direct replacements for DBLS152G C1G?

A: Yes. Both Vishay parts are parametric equivalents meeting all electrical ratings (100 V, 1.5 A), forward voltage specifications (1.1 V @ 1.5 A), and operating temperature range (-55°C ~ 150°C). The 4-SMD, Gull Wing package is identical across all three parts, enabling direct PCB substitution.

Q: What is the significance of the reverse leakage current difference (2 µA vs. 5 µA)?

A: The reverse leakage current specification indicates the small current flowing through the diode in reverse bias condition. The DBLS152G C1G specifies 2 µA while the Vishay substitutes specify 5 µA, both measured at 100 V. This difference remains within standard bridge rectifier tolerances and does not affect functional performance in typical AC-to-DC conversion applications.

Q: Are all three parts RoHS3 compliant?

A: Yes. DBLS152G C1G, DF1501S-E3/45, and DFL1501S-E3/45 are all ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial applications.

Q: What is the difference between DF1501S-E3/45 and DFL1501S-E3/45?

A: Both parts are manufactured by Vishay General Semiconductor - Diodes Division and share identical electrical specifications and package configurations. The difference in part number designation (DF versus DFL) reflects internal Vishay product line categorization but does not affect electrical or mechanical compatibility. Both are functionally equivalent substitutes for the DBLS152G C1G.

Q: Is the 4-SMD, Gull Wing package compatible with standard PCB assembly equipment?

A: Yes. The 4-SMD, Gull Wing package is a standard surface mount configuration compatible with conventional pick-and-place assembly equipment and reflow soldering processes used in electronics manufacturing.

Q: What is Moisture Sensitivity Level 1 (Unlimited)?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts do not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and supply chain handling.
