Key Parameters

Substitute Part Grouping Explanation

Substitute identification is strictly based on the following key allowed parameters within the Diodes, Rectifiers category: technology (Schottky), maximum reverse voltage, average rectified current, forward voltage at test current, reverse recovery time, reverse leakage current, mounting type, package/case, product status, and compliance certifications. Only models matching these explicit parameters are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both BAT54A RF and BAT54A RFG are listed as Active products from the same manufacturer with identical compliance certifications, including ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited). Selection between these options can be based on product availability and stock levels, as both meet the required regulatory and environmental criteria specified.

Frequently Asked Questions (FAQ)

Q1: What parameters must be matched when substituting BAT54A RF in a design?
A1: Substitute selection requires matching technology, maximum DC reverse voltage, average rectified current rating, forward voltage at specified current, reverse recovery time, reverse leakage current, mounting type, package/case, product status, and compliance certifications.

Q2: Are BAT54A RF and BAT54A RFG compatible for direct interchange in PCB layouts?
A2: Both models share the same surface mount package type (TO-236-3, SC-59, SOT-23-3) and supplier device package (SOT-23), ensuring compatibility in PCBs designed for this footprint.

Q3: Is there any difference in regulatory compliance between the main and substitute parts?
A3: Both BAT54A RF and BAT54A RFG are RoHS3 compliant, REACH Unaffected, and Moisture Sensitivity Level (MSL) classified as 1 (Unlimited).

Q4: Why is it necessary to verify product status when choosing substitutes?
A4: Active product status ensures ongoing manufacturer support and supply availability.

Q5: What mounting considerations should be accounted for during substitution?
A5: Mounting type must remain Surface Mount and the package/case should match TO-236-3, SC-59, SOT-23-3 for assembly and automated placement compatibility.
