RB481KTL Equivalent & Substitute Parts Reference

Part Overview

The RB481KTL, manufactured by Rohm Semiconductor, is a Schottky diode array with 2 independent 30V 200mA diodes in a UMD4 (SC-82A, SOT-343) surface mount package. The device features low forward voltage and low reverse leakage current, targeting small signal rectification applications. The product is currently active and compliant with RoHS3 and REACH regulations with high inventory. Identifying direct substitutes is essential for maintaining supply chain continuity, meeting regulatory requirements, and supporting alternate second-source approvals when identical part performance and compliance are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching or exceeding the following parameters: diode technology (Schottky), reverse voltage (30V), average rectified current (200mA), forward voltage at 200mA, reverse leakage current at specified voltage, surface mount package, and regulatory compliance (RoHS3, REACH). Diodes must align in functionality and key performance limits to qualify as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Moisture Sensitivity Level (MSL 1) and regulatory compliance status are met for both devices based on provided data, supporting their use in applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q1: What are the primary parameters to verify when selecting a substitute for RB481KTL in the Diodes, Rectifiers category?
A1: The primary parameters include diode technology (Schottky), reverse voltage rating, average rectified current, maximum forward voltage, reverse leakage current, surface mount compatibility, and compliance statuses (RoHS3, REACH).

Q2: Is RB521SM-30T2R a direct electrical replacement for RB481KTL?
A2: RB521SM-30T2R matches the key electrical parameters of the RB481KTL including voltage rating, current rating, forward voltage at 200 mA, and reverse leakage current.

Q3: Are there differences in package types that should be considered?
A3: RB481KTL uses SC-82A, SOT-343 (UMD4) while RB521SM-30T2R uses SC-79, SOD-523 (EMD2). Package compatibility must be evaluated based on the PCB footprint.

Q4: Does Moisture Sensitivity Level (MSL) affect substitution?
A4: Both parts are MSL 1, indicating unlimited floor life at ≤30°C/85% RH, which is suitable for most assembly processes as specified.

Q5: Can regulatory compliance parameters help in selecting an appropriate substitute?
A5: Yes, both components are compliant with ROHS3 and are unaffected by REACH, which supports substitution when regulatory requirements are enforced.
