DF1501S Bridge Rectifier Equivalent & Substitute Parts

Part Overview

The DF1501S is a single-phase bridge rectifier manufactured by Diodes Incorporated, rated for 100 V peak reverse voltage and 1.5 A average rectified current. It is packaged in a 4-SMD, Gull Wing surface mount configuration (DF-S package) and is currently in active production status. The DF1501S is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when a primary part reaches end-of-life status, experiences supply constraints, or when design flexibility permits component interchange. The DF01S represents a manufacturer-recommended substitute option, though it carries a "Not For New Designs" status from onsemi.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF1501S is determined by electrical and mechanical parameter alignment within the single-phase bridge rectifier category. The critical parameters that define substitutability are:

• Voltage - Peak Reverse (Max): 100 V
• Current - Average Rectified (Io): 1.5 A
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Diode Type: Single Phase
• Technology: Standard

The DF01S from onsemi meets these core electrical specifications and maintains the same surface mount package configuration. Both parts are ROHS3 compliant and carry MSL 1 ratings. The primary distinction is the operating temperature range and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The DF01S is electrically and mechanically compatible with the DF1501S for applications requiring a 100 V, 1.5 A single-phase bridge rectifier in surface mount configuration. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity ratings.

Selection between these parts should be based on:

• Product lifecycle requirements: The DF1501S is in active production status, while the DF01S is designated "Not For New Designs." New designs should prioritize the DF1501S.
• Operating temperature range: The DF1501S supports -65°C to 150°C, while the DF01S supports -55°C to 150°C. Applications requiring operation below -55°C require the DF1501S.
• Reverse leakage characteristics: The DF01S exhibits lower reverse leakage (5 µA vs. 10 µA at 100 V), which may be advantageous in low-leakage applications.
• Supply availability: The DF01S may be selected when DF1501S supply is constrained, provided application temperature and lifecycle requirements permit.

Frequently Asked Questions (FAQ)

Q: Can the DF01S directly replace the DF1501S in existing designs?

A: The DF01S is electrically and mechanically compatible with the DF1501S. However, verify that your application does not require operation below -55°C, as the DF01S minimum operating temperature is -55°C versus -65°C for the DF1501S. Additionally, the DF01S carries a "Not For New Designs" status from onsemi.

Q: What are the key differences between these parts?

A: The primary differences are operating temperature range (-65°C to 150°C for DF1501S versus -55°C to 150°C for DF01S) and reverse leakage current (10 µA for DF1501S versus 5 µA for DF01S at 100 V). All other electrical and mechanical parameters are identical.

Q: Are both parts RoHS compliant?

A: Yes, both the DF1501S and DF01S are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity ratings.

Q: What package configurations are used?

A: Both parts use identical 4-SMD, Gull Wing surface mount packages (DF-S for DF1501S and 4-SDIP for DF01S), ensuring mechanical compatibility on PCBs designed for either part.

Q: Which part should be specified for new designs?

A: The DF1501S should be specified for new designs, as it maintains active production status. The DF01S is suitable only for legacy design updates or supply contingency scenarios where application requirements permit its use.
