Key Parameters

Substitute Part Grouping Explanation

Substitute or equivalent diode array rectifier parts must have matching electrical, mechanical, and compliance parameters. The following critical parameters were used for equivalence: Diode Configuration, Technology, Voltage - DC Reverse (Vr) (Max), Current - Average Rectified (Io) (per Diode), Voltage - Forward (Vf) (Max) @ If, Current - Reverse Leakage @ Vr, Operating Temperature - Junction, Package / Case, Compliance Certifications, and Mounting Type.

Parameter Comparison

Engineering Selection Recommendations

Both RB238NS-40FHTL and its substitute RB238NS-40TL are classified as active, maintain identical compliance certifications (RoHS3, AEC-Q101, REACH unaffected, ECCN EAR99), and share the same Moisture Sensitivity Level rating. The packaging is the only distinction, with RB238NS-40FHTL available in Cut Tape (CT) & Digi-Reel® and RB238NS-40TL in Tape & Reel (TR). Selection should be based on supply preference, inventory requirements, and automated assembly process compatibility.

Frequently Asked Questions (FAQ)

Q1: Are RB238NS-40FHTL and RB238NS-40TL interchangeable in existing PCB layouts?
A1: Both share the same mechanical dimensions and package (TO-263-3, D2PAK (2 Leads + Tab), TO-263AB) and are mechanically interchangeable.

Q2: What key parameters ensure electrical equivalence between RB238NS-40FHTL and RB238NS-40TL?
A2: Electrical equivalence is ensured by identical diode configuration, technology, voltage ratings, current ratings, forward voltage, reverse leakage, and maximum junction temperature.

Q3: Are there differences in environmental or regulatory compliance?
A3: Both models are RoHS3 compliant, AEC-Q101 qualified, and REACH unaffected.

Q4: Does the choice of packaging (CT, Digi-Reel®, TR) affect functional performance?
A4: Packaging type does not impact electrical or thermal performance. It only affects inventory management and assembly process compatibility.

Q5: What documentation should be consulted to confirm proper substitute selection?
A5: All substitution criteria here are directly supported by explicit manufacturer parameters provided for both RB238NS-40FHTL and RB238NS-40TL.
