Key Parameters

Substitute Part Grouping Explanation

Substitute selection for the ES 1F diode is strictly based on matching the following key parameters:

• Voltage - DC Reverse (Vr) (Max): 1500 V
• Current - Average Rectified (Io): 500 mA
• Voltage - Forward (Vf) (Max) @ If: 2 V @ 500 mA
• Speed: Standard Recovery >500ns, >200mA (Io)
• Reverse Recovery Time (trr): 1.5 µs
• Current - Reverse Leakage @ Vr: 10 µA @ 1500 V
• Mounting Type: Through Hole
• Package / Case: Axial
• Operating Temperature - Junction: -40°C ~ 150°C
• RoHS Status: RoHS Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Only devices matching all explicit electrical, mechanical, and compliance parameters are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Based on the product status, the ES 1F diode is obsolete while the ES01F remains active. Both parts hold RoHS compliance and identical Moisture Sensitivity Level (MSL) ratings. For direct replacement and ongoing production, selection of ES01F maintains all certified compatibility standards within the defined parameters.

Frequently Asked Questions (FAQ)

Q: What determines if ES01F is a valid substitute for ES 1F?
A: The substitution is valid if all electrical, mechanical, and compliance specifications match, including voltage rating, current rating, reverse recovery time, mounting type, and RoHS status.

Q: Is the package type of ES01F compatible with existing ES 1F board layouts?
A: Both ES 1F and ES01F feature an axial through-hole package, ensuring physical compatibility.

Q: Are the operating temperature ranges the same for both diodes?
A: Yes, both are rated for a junction temperature between -40°C and 150°C.

Q: Does the Moisture Sensitivity Level affect substitution selection?
A: Both components are specified at MSL 1 (Unlimited), allowing unrestricted storage and handling under normal conditions.

Q: Will switching to ES01F impact RoHS compliance?
A: ES01F is documented as RoHS Compliant, matching the ES 1F compliance requirement.
