Equivalent & Substitute Parts for RB541VM-40TE-17

Part Overview

The RB541VM-40TE-17 from Rohm Semiconductor is a Schottky diode in the Diodes, Rectifiers category. It is designed for 40 V reverse voltage and 200 mA average rectified current, offered in the surface-mount UMD2 package (SC-90, SOD-323F), RoHS3 compliant, and currently active status. The part is widely used in compact electronic assemblies requiring fast-switching, low leakage, and small-signal rectification. Due to potential inventory constraints, automotive qualification requirements, or product status changes, engineers may need to find alternatives or parametric equivalent models for RB541VM-40TE-17.

Substitute Part Grouping Explanation

The substitute parts are grouped strictly according to the following key parameters: technology (Schottky), package/case format (SC-90, SOD-323F surface mount), supplier device package (UMD2 or SOD-323F), maximum DC reverse voltage (40 V), average rectified current rating (200 mA), maximum forward voltage (Vf), reverse leakage current (@ Vr), operating junction temperature, compliance status (RoHS, REACH), moisture sensitivity level, and product status. Only parts fully matching these critical parameters or with formal automotive qualification, as documented in the input, are designated parametric equivalents or similar substitutes.

Engineering Selection Recommendations

For direct substitution of RB541VM-40TE-17, select RB541VM-40FHTE-17 for applications requiring automotive qualification (AEC-Q101) or when RB541VM-40TE-17 is unavailable, noting its “Not For New Designs” product status. PMEG4002EJ,115 meets Schottky technology, SOD-323F package format, and all specified parametric requirements with additional operating temperature margin and automotive qualification (AEC-Q100), and retains “Active” product status. All listed parts are compliant with ROHS3, have unlimited moisture sensitivity level (MSL 1), and are REACH unaffected. Selection should reflect required qualification, product status, and stocking conditions documented in the input.

Frequently Asked Questions (FAQ)

Q1: What makes RB541VM-40TE-17 interchangeable with RB541VM-40FHTE-17?
Both feature identical technology, package type, electrical ratings, compliance, and mounting specifications. RB541VM-40FHTE-17 adds automotive qualification (AEC-Q101), but is “Not For New Designs”.

Q2: Is PMEG4002EJ,115 a parametric substitute for RB541VM-40TE-17?
Yes; PMEG4002EJ,115 matches critical Schottky technology, package format (SOD-323F), electrical ratings, compliance, and mounting type. It also supports automotive environments per AEC-Q100.

Q3: Are all substitute diodes suitable for surface mount PCB assembly?
Yes; all listed parts are surface mount with the SC-90/SOD-323F package compatibility.

Q4: What compliance standards are covered for these substitutes?
RB541VM-40TE-17, RB541VM-40FHTE-17, and PMEG4002EJ,115 are ROHS3 compliant, have unlimited MSL (1), and are REACH unaffected.

Q5: When should “Not For New Designs” status be considered in substituting?
If long-term supply stability or design lifecycle is critical, select substitutes with “Active” status; otherwise, RB541VM-40FHTE-17 can be used where automotive grade is essential.

Q6: What are the key package and handling similarities for these parts?
All parts use the small footprint SC-90/SOD-323F case for surface mounting, supporting automated pick-and-place assembly and comparable mechanical outline.

Q7: How are voltage, current, and leakage parameters matched for substitution?
Substitution has been strictly based on the voltage - DC reverse (40V), average rectified current (200mA), maximum forward voltage (Vf), and reverse leakage current, as reflected in the comparison table above.
