Equivalent & Substitute Parts Reference for RB481KFSTL

Part Overview

The RB481KFSTL (Rohm Semiconductor) is a surface mount Schottky diode array consisting of 2 independent diodes, specifically designed for small signal rectification under 200mA average current at 30V reverse voltage. The device is housed in a SC-82A, SOT-343 package and is ROHS3 compliant. Its product status is “Not For New Designs,” indicating that design-in of new projects with this part should be avoided in favor of active alternatives. It is essential to identify parametric substitutes for continued production support and inventory risk mitigation.

Substitute Part Grouping Explanation

Substitute parts are identified based on matching values in core functional and compliance parameters, including diode configuration, technology, maximum reverse voltage, average rectified current, forward voltage at rated current, reverse leakage current, package type, mounting style, operating temperature, RoHS and REACH status, and MSL. Only those parts meeting all listed parameters are included as substitutes for RB481KFSTL.

Parameter Comparison

Engineering Selection Recommendations

RB481KFSTL is designated “Not For New Designs”. Substitute part RB481KTL, also from Rohm Semiconductor, is listed as “Active” and maintains full compliance with ROHS3, REACH, and MSL 1 standards. Both parts share an identical parametric profile and package, enabling direct substitution within existing applications requiring compliance with the listed standards and device certifications.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for RB481KFSTL?
A1: Substitutes must match diode configuration, technology, reverse voltage rating, average rectified current, forward voltage at rated current, reverse leakage current, mounting type, package specification, operating temperature, RoHS/REACH compliance, and moisture sensitivity level.

Q2: Is RB481KTL compatible with the same PCB footprint as RB481KFSTL?
A2: Both parts use the SC-82A, SOT-343 package and UMD4 supplier device package, supporting direct footprint compatibility on surface mount assemblies.

Q3: Are there differences in electrical performance between RB481KFSTL and RB481KTL?
A3: All key electrical parameters provided (reverse voltage, forward voltage, current rating, leakage, operating temperature) are identical between RB481KFSTL and RB481KTL.

Q4: Is there any difference in compliance or reliability ratings?
A4: Both diodes are ROHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited), indicating equivalent compliance and reliability in manufacturing and operational environments.

Q5: Can RB481KTL be used for new designs where RB481KFSTL is currently specified?
A5: RB481KTL is designated “Active” and shares all core parametric and compliance ratings with RB481KFSTL, allowing its use in new and legacy designs where these parameters are mandatory.
