Equivalent & Substitute Parts for RB550SS-30T2R

Part Overview

The RB550SS-30T2R is a Schottky diode in the Diodes, Rectifiers category, manufactured by Rohm Semiconductor. It provides a 30V maximum DC reverse voltage and 500mA average rectified current, designed for surface mount (KMD2 package). The product is classified as obsolete, necessitating the use of equivalent or substitute parts for new designs and ongoing maintenance. Engineering substitution is required to maintain compliance with electrical and mechanical specifications, as well as inventory continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for RB550SS-30T2R are identified strictly by matching core electrical parameters: Schottky technology, 30 V maximum DC reverse voltage, 500 mA average rectified current, rapid switching speed (Fast Recovery =< 500ns), surface mount design, and compliance statuses (ROHS3, REACH, MSL 1). Only products in the Diodes, Rectifiers category with these provided parameters are included. Package and supplier device package differences are noted but do not affect basic electrical substitution.

Parameter Comparison

Engineering Selection Recommendations

Reliance on substitute models such as RB550VM-30TE-17 and BAS3005B02VH6327XTSA1 is advised based on the obsolete status of RB550SS-30T2R. Each substitute part fulfills provided criteria: Schottky technology, matching voltage and current ratings, current product status (Active), ROHS3 compliance, unrestricted moisture sensitivity level (MSL 1), and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q1: What defines a compatible substitute for RB550SS-30T2R?
A1: Compatibility is established by identical Schottky technology, maximum reverse voltage of 30 V, average rectified current of 500mA, fast recovery speed, surface mount configuration, and compliance credentials.

Q2: How do packaging differences (case/package) affect substitution?
A2: Substitute parts in categories such as SC-90 (SOD-323F), SC-79 (SOD-523), and PG-SC79-2 may have physical footprint differences. These must be considered for board design but do not affect electrical equivalence according to supplied parameters.

Q3: Are substitute parts actively supplied and compliant?
A3: RB550VM-30TE-17 and BAS3005B02VH6327XTSA1 are listed as active, with ROHS3 compliance, MSL 1 (Unlimited), and REACH unaffected status matching the original part’s certifications.

Q4: Which parameters are essential for assuring electrical and mechanical compatibility in substitution?
A4: Key parameters are Schottky technology, Vr (30 V), Io (500mA), fast recovery speed, mounting type (Surface Mount), compliance status, and product status.

Q5: Can the substitute parts be directly used without further selection or modification?
A5: Selection is based solely on the provided electrical, mechanical, and compliance parameters for this category. Further considerations regarding package and form factor depend on application requirements outside the provided data.
