RB160SS-40T2R Equivalent & Substitute Parts Reference

Part Overview

The RB160SS-40T2R from Rohm Semiconductor is a Schottky diode rated for 40 V reverse voltage and 1 A average rectified current in a surface mount 2-SMD, No Lead (KMD2) package. The product is obsolete, necessitating the identification of compatible substitute models for new designs or maintenance where the original part is no longer available. Alternatives must match critical electrical and mechanical parameters to ensure reliable substitution without affecting circuit performance.

Engineering Selection Recommendations

Substitute selection is supported by full compliance with RoHS3, REACH status, and MSL level 1. Product status indicates RB160SS-40T2R is obsolete, while RB161QS-40T18R and CCS15S40,L3F are active. All listed substitute parts meet the required compliance and certification criteria.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select substitutes for RB160SS-40T2R?
A1: Only parts matching Schottky technology, reverse voltage rating, minimum average rectified current, package type (2-SMD, No Lead), and compliance status (RoHS3, REACH) are considered.

Q2: Are all substitute parts in the same package type as the original RB160SS-40T2R?
A2: All substitute parts feature a surface mount 2-SMD, No Lead package, aligning with the original’s mechanical mounting requirements.

Q3: How do reverse leakage and forward voltage parameters compare among the substitutes?
A3: Substitute parts feature comparable forward voltage and reverse leakage parameters within the specified voltage and current conditions per the provided details.

Q4: Is there any difference in compliance or environmental status among the listed substitutes?
A4: All substitutes are RoHS3 compliant, have REACH Unaffected status, and MSL level 1, matching the original part’s certifications.

Q5: Is there any difference in operating junction temperature?
A5: The RB161QS-40T18R matches the 150°C maximum junction temperature of the RB160SS-40T2R. The CCS15S40,L3F substitute specifies a 125°C maximum junction temperature.
