Equivalent & Substitute Parts for CMFSH-3I TR TIN/LEAD

Part Overview

The CMFSH-3I TR TIN/LEAD is a diode array containing two independent Schottky diodes, each with a maximum DC reverse voltage rating of 30 V and an average rectified current rating of 100 mA (DC). The package type is SOT-143 (TO-253-4, TO-253AA) and the mounting style is surface mount. This product is currently listed as Obsolete, making it necessary to identify equivalent and substitute rectifier diode arrays with matching electrical and mechanical parameters for continued application support and design maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is based strictly on matching the key electrical and mechanical parameters: diode configuration, Schottky technology, maximum DC reverse voltage, average rectified current per diode, forward voltage at specified current, speed/class, reverse recovery time, maximum reverse leakage current, operating temperature range, mounting type, package/case, supplier device package, RoHS/REACH compliance, ECCN, and HTSUS classification. Only parts that conform to these listed criteria are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Due to the obsolete status of CMFSH-3I TR TIN/LEAD, selection of a substitute part such as BAT74,235 is based on matching electrical ratings, package compatibility, and regulatory compliance (ROHS3, REACH, ECCN, HTSUS). BAT74,235 is currently active, conforms to the required compliance standards, and is available in a compatible surface-mount package for Diodes, Rectifiers applications.

Frequently Asked Questions (FAQ)

Q1: What technical parameters must match to substitute the CMFSH-3I TR TIN/LEAD?
A1: Diode configuration, technology, maximum DC reverse voltage, average rectified current per diode, forward voltage at specified current, speed/class, reverse recovery time, maximum reverse leakage, operating temperature, mounting type, package/case, and device package must match.

Q2: Are SOT-143 and SOT-143B packages interchangeable for this category?
A2: Both SOT-143 and SOT-143B are associated with TO-253-4, TO-253AA mechanical footprints for Diodes, Rectifiers, allowing physical compatibility for surface mount assembly.

Q3: Does ROHS3 and REACH compliance affect substitute selection?
A3: ROHS3 and REACH compliance are required for substitute selection in compliance-driven applications. Substitute parts must carry equivalent compliance certification.

Q4: Is it necessary for substitute rectifier diodes to match reverse recovery time and leakage current exactly?
A4: Substitute evaluation is strictly based on provided parameters. Reverse recovery time and maximum reverse leakage must not exceed the values specified in the main part for compatibility.

Q5: Why is a substitute needed for obsolete diode rectifier models?
A5: Obsolete status indicates the manufacturer does not supply or support the product. Substitutes are selected to maintain continuous operation, assembly, or repair without deviation from the required specifications.

Q6: How is package compatibility ensured during substitution?
A6: Substitution is limited to parts specifying the same package/case and supplier device package code, ensuring direct mechanical and footprint compatibility for surface mounting.
