Equivalent & Substitute Parts Reference for RF305B6STL

Part Overview

The RF305B6STL, manufactured by Rohm Semiconductor, is a standard fast-recovery rectifier diode rated for 600 V reverse voltage and 3 A average rectified current, supplied in a surface mount TO-252-3 (DPAK/SC-63) package. The product status of RF305B6STL is “Obsolete,” necessitating the identification of direct or similar substitute parts to maintain compatibility in existing designs, support repairs, or ensure long-term manufacturing continuity. The selection of equivalent parts is guided solely by matching the explicit electrical characteristics and physical package parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent parts for the RF305B6STL are determined based strictly on the following parameters: maximum reverse voltage (Vr), average rectified current (Io), recovery speed classification, mounting type, and physical package. All substitute selections retain ROHS3 compliance, MSL 1 unlimited moisture sensitivity, and surface mount compatibility using the TO-252-3 (DPAK/SC-63) footprint. Differences in active/obsolete status and inventory are also considered.

Parameter Comparison

Engineering Selection Recommendations

Selection between the RF305B6STL and substitute parts is based on product lifecycle status. Both substitute options, RF305BM6STL and STTH506B-TR, are listed as “Active.” All parts meet ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level. For applications with REACH certification requirements, verify the explicitly provided REACH status for each device.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to select substitute diodes for the RF305B6STL?
A1: Substitutes are selected based exclusively on maximum reverse voltage (Vr), average rectified current (Io), speed classification, mounting type, and physical package consistency.

Q2: Are there any differences in packaging or mounting between these substitutes?
A2: All options are surface mount devices using the TO-252-3, DPAK package with 2 leads and a tab, ensuring compatibility with the same board layouts.

Q3: Should product lifecycle status affect the choice of substitute?
A3: The main part, RF305B6STL, is obsolete. Substitute parts RF305BM6STL and STTH506B-TR are both active, favoring their use for ongoing or new designs.

Q4: Do substitute parts have equivalent compliance certifications?
A4: All substitutes are specified as ROHS3 compliant and have MSL 1 (Unlimited). RF305B6STL and RF305BM6STL are listed as REACH unaffected; confirm REACH status for STTH506B-TR if needed.

Q5: Do substitute parts have stricter or differing electrical limits?
A5: The substitute parts meet or exceed the original electrical parameters specified for reverse voltage, current capacity, and speed classification.
