Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by matching the following key electrical, mechanical, and compliance parameters:

• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Grade and Qualification: Automotive, AEC-Q101
• Mounting Type and Package / Case
• RoHS and REACH Compliance
• Moisture Sensitivity Level (MSL)
• ECCN and HTSUS code

Only substitute parts that align with these parameters are grouped as viable equivalents.

Parameter Comparison

Engineering Selection Recommendations

The RB511SM-40FHT2R is marked “Not For New Designs.” Selecting a substitute such as NSVR0240V2T1G is supported by equivalent or exceeding electrical ratings (same Vr, higher Io), identical automotive grade and AEC-Q101 qualification, RoHS3 and REACH compliance, same surface mount package, and matching MSL, ECCN, and HTSUS codes. All listed compliance criteria are met by both parts.

Frequently Asked Questions (FAQ)

Q1: What criteria must be satisfied for a diode to serve as a substitute for RB511SM-40FHT2R?
A: Substitute selection requires matching Schottky technology, 40 V maximum reverse voltage, automotive grade, AEC-Q101 qualification, surface mount SOD-523 or SC-79 package, and having RoHS3 and REACH compliance.

Q2: Is the substitute NSVR0240V2T1G identical in package type and mounting?
A: Both RB511SM-40FHT2R and NSVR0240V2T1G feature surface mount SOD-523 (SC-79) packages.

Q3: Do both parts comply with automotive industry standards?
A: Both components are automotive grade and AEC-Q101 qualified.

Q4: Is RoHS3 and REACH status consistent across the listed substitute?
A: Both diodes are RoHS3 compliant and REACH unaffected.

Q5: Are there differences in current handling between the main and substitute part?
A: The substitute part (NSVR0240V2T1G) has a higher average rectified current rating (250mA vs. 100mA). All other key parameters for automotive and electrical compatibility are matched.
