Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF02SA-E3/45 are identified based on the following critical parameters:

• Voltage - Peak Reverse (Max): 200 V minimum
• Current - Average Rectified (Io): 1 A or greater
• Diode Type: Single Phase
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -55°C to 150°C or wider
• RoHS Status: ROHS3 Compliant

Parts meeting these specifications are electrically and mechanically compatible for direct substitution in applications designed for the DF02SA-E3/45.

Parameter Comparison

Engineering Selection Recommendations

DF02S-E3/45 (Vishay) is the primary parametric equivalent, matching all electrical and mechanical specifications of the DF02SA-E3/45. Both parts are manufactured by Vishay and maintain identical ratings for voltage, current, forward voltage drop, and reverse leakage. Both are active products suitable for new designs and carry ROHS3 compliance.

DF02S (onsemi) is a functional substitute with higher current rating (1.5 A versus 1 A) and slightly elevated reverse leakage (10 µA versus 5 µA). This part is marked "Not For New Designs" and should be used only when existing inventory constraints or legacy system requirements necessitate its use. The higher current rating provides design margin but does not alter the 200 V voltage specification or thermal operating range.

Frequently Asked Questions (FAQ)

Q: Can DF02S-E3/45 replace DF02SA-E3/45 directly?

A: Yes. DF02S-E3/45 is a parametric equivalent with identical electrical specifications, voltage rating, current rating, forward voltage drop, reverse leakage, operating temperature range, and package configuration. Direct substitution is supported.

Q: Is DF02S (onsemi) a suitable replacement?

A: DF02S (onsemi) meets the minimum voltage and current requirements and shares the same package type. However, it carries a "Not For New Designs" status and exhibits higher reverse leakage (10 µA versus 5 µA). Use only when existing inventory or legacy system constraints apply.

Q: What are the key parameters that determine substitution compatibility?

A: Peak reverse voltage (200 V minimum), average rectified current (1 A or greater), forward voltage characteristics, reverse leakage current, operating temperature range (-55°C to 150°C), surface mount packaging, and 4-SMD Gull Wing case style are the primary criteria.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, matching the environmental and regulatory status of the DF02SA-E3/45.

Q: Does the higher current rating of DF02S (onsemi) affect circuit design?

A: No. The 1.5 A rating of DF02S (onsemi) exceeds the 1 A requirement of the original part. This provides additional current capacity without affecting voltage specifications, thermal characteristics, or package footprint. Forward voltage drop remains 1.1 V at the rated current of each part.
