FR40J02 Equivalent & Substitute Parts Reference

Part Overview

The FR40J02 from GeneSiC Semiconductor is a standard recovery rectifier diode with a maximum reverse voltage of 600 V, an average forward current of 40 A, and a chassis, stud mount DO-203AB (DO-5) package. It is classified as active and RoHS compliant, making it suitable for designs requiring a reliable, RoHS-compliant rectifier solution. Alternative models are required for continued production in cases of supply limitations, multiple sourcing requirements, or manufacturer preference, provided key electrical and mechanical parameters are matched.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GeneSiC Semiconductor FR40J02 are selected strictly based on matches in category (Diodes, Rectifiers), mounting style (Chassis, Stud Mount), package (DO-203AB, DO-5), voltage rating, average forward current, speed (Fast Recovery), reverse recovery time, and RoHS compliance. Electrical and mechanical equivalence across these parameters is necessary for valid substitution within this product category. The list of key parameters used in this grouping includes:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Fast Recovery Characteristics)
• Reverse Recovery Time (trr)
• Current - Reverse Leakage @ Vr
• Mounting Type
• Package / Case
• Operating Temperature - Junction
• RoHS Status

Parameter Comparison

Engineering Selection Recommendations

Select substitute rectifier diodes with the same product status (active), RoHS compliant or ROHS3 compliant designation, and matching Moisture Sensitivity Level (MSL 1 - unlimited). Ensure all inventory is specified as "New Original In Stock" per supplier data for consistent quality and traceability.

Frequently Asked Questions (FAQ)

Q1: Which parameters must be matched when selecting an equivalent for the FR40J02?
A1: The essential parameters are voltage rating, average forward current, recovery speed, reverse recovery time, reverse leakage current, mounting type, package/case, operating temperature, and RoHS compliance.

Q2: Can DO-203AB, DO-5, Stud packages be interchanged directly?
A2: Substitution within the DO-203AB, DO-5, Stud family ensures mechanical and mounting compatibility.

Q3: Is RoHS compliance status identical between substitutes?
A3: Main and substitute parts are RoHS or ROHS3 compliant, both meeting lead-free and hazardous substance requirements.

Q4: Is operating temperature a differentiating factor among these models?
A4: Both the FR40J02 and the VS-40HFL60S02 specify an operating junction temperature range of -40°C to 125°C.

Q5: Are inventory considerations included in substitute selection?
A5: Substitute listing specifies available inventory as "New Original In Stock," supporting procurement reliability within the supplied batch.
