Substitute Part Grouping Explanation

Substitute parts for the DF1502S-E3/45 are qualified based on the following electrical and mechanical parameters:

• Diode Type: Single Phase (required match)
• Technology: Standard (required match)
• Voltage - Peak Reverse (Max): 200 V (required match)
• Current - Average Rectified (Io): 1.5 A (required match)
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 1.5 A (required match)
• Mounting Type: Surface Mount (required match)
• Package / Case: 4-SMD, Gull Wing (required match)
• RoHS Status: ROHS3 Compliant (required match)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (required match)

The identified substitute parts DF1502S and DF1502S-T meet all critical electrical specifications and mechanical requirements. Variations in reverse leakage current and operating temperature range represent acceptable parameter tolerances within the bridge rectifier product category.

Parameter Comparison

Engineering Selection Recommendations

Both DF1502S and DF1502S-T are qualified substitutes for the DF1502S-E3/45 based on electrical and mechanical parameter equivalence. All three parts maintain Active product status and ROHS3 compliance. The substitute parts from Diodes Incorporated offer extended operating temperature ranges (-65°C minimum versus -55°C), providing additional thermal margin in low-temperature applications. Selection between substitute options should be based on packaging requirements: DF1502S is supplied in Bulk packaging, while DF1502S-T is available in Cut Tape (CT) & Digi-Reel® format for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: What electrical parameters must match for a part to be considered a substitute for the DF1502S-E3/45?

A: The substitute part must maintain identical Diode Type (Single Phase), Technology (Standard), Voltage - Peak Reverse (200 V), Current - Average Rectified (1.5 A), Voltage - Forward (1.1 V @ 1.5 A), Mounting Type (Surface Mount), and Package / Case (4-SMD, Gull Wing). These parameters define the functional equivalence of the bridge rectifier within the product category.

Q: Are there differences in reverse leakage current between the main part and substitutes?

A: Yes. The DF1502S-E3/45 specifies 5 µA @ 200 V reverse leakage. The DF1502S specifies 10 µA @ 100 V, and the DF1502S-T specifies 10 µA @ 200 V. These variations remain within acceptable tolerances for standard bridge rectifier applications and do not affect functional substitution.

Q: Can the operating temperature range difference impact part selection?

A: The DF1502S-E3/45 operates from -55°C to 150°C, while both substitute parts operate from -65°C to 150°C. The extended low-temperature range of substitute parts provides additional design margin but does not restrict their use in applications requiring the original temperature specification.

Q: What is the difference between the packaging options for substitute parts?

A: DF1502S is supplied in Bulk packaging for manual handling and stocking. DF1502S-T is supplied in Cut Tape (CT) & Digi-Reel® format, optimized for automated pick-and-place assembly equipment. Both contain identical electrical components; packaging selection depends on manufacturing process requirements.

Q: Are all three parts RoHS3 compliant?

A: Yes. The DF1502S-E3/45, DF1502S, and DF1502S-T are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), meeting environmental and regulatory requirements for industrial and commercial applications.
