Key Parameters

Substitute Part Grouping Explanation

Substitutes are identified strictly by matching the following parameters: diode configuration, technology, voltage rating, current handling, forward voltage, reverse leakage, speed, operating temperature, grade, qualification, package type, RoHS compliance, moisture sensitivity level, and REACH status. Only products matching all listed criteria are included.

Parameter Comparison

Engineering Selection Recommendations

The RB558WMFHTL is classified as "Not For New Designs," making substitute selection necessary for ongoing engineering, design, and manufacturing. The RB558WMTL meets the same RoHS3 compliance, REACH status, MSL, package, and all critical electrical parameters supplied, with the exception of a specified maximum junction temperature. For applications relying specifically on automotive grade or AEC-Q101 qualification, only the main part RB558WMFHTL lists these parameters.

Frequently Asked Questions (FAQ)

Q1: What electrical and mechanical parameters must match when substituting RB558WMFHTL?
A1: Key parameters include diode configuration, Schottky technology, maximum reverse voltage, average rectified current, forward voltage, reverse leakage current, speed class, package/case type, mounting type, RoHS and REACH compliance, MSL, ECCN, and HTSUS.

Q2: Is package compatibility ensured with RB558WMTL?
A2: Yes. Both RB558WMFHTL and RB558WMTL use the SC-89, SOT-490 (EMD3F) surface-mount package.

Q3: Are there any differences in automotive grade or AEC-Q101 qualification?
A3: Only RB558WMFHTL indicates automotive grade and AEC-Q101 qualification within provided input parameters. RB558WMTL does not specify these fields.

Q4: Is full electrical performance maintained when using RB558WMTL as a substitute?
A4: All explicitly listed electrical parameters (voltage, current, forward voltage, reverse leakage, speed) are matched between RB558WMFHTL and RB558WMTL.

Q5: What compliance certifications apply to the substitute?
A5: Both parts are ROHS3 compliant and REACH unaffected, with an MSL of 1 (unlimited) and ECCN classification EAR99.
