Substitute Part Grouping Explanation

Substitute parts are selected by strictly matching essential parameters required for compatibility within the Diodes, Rectifiers category. The following criteria are used for equivalency:

Voltage - DC Reverse (Vr) (Max)
Current - Average Rectified (Io)
Voltage - Forward (Vf) (Max) @ specified If
Recovery Speed and Reverse Recovery Time (trr)
Reverse Leakage Current @ Vr
Mounting Type and Package / Case
RoHS and REACH compliance
Moisture Sensitivity Level (MSL)
Operating Temperature - Junction

Only parts whose datasheet and specifications match or exceed these parameters are considered as substitutes.

Engineering Selection Recommendations

Based on the product status "Not For New Designs" for RFX10TF6S, alternatives must maintain RoHS and REACH compliance and meet or exceed the provided MSL where possible. Substitute parts listed meet these compliance requirements and match the specified electrical/mechanical parameters. Only devices explicitly matching these compliance and certification criteria are included.

Frequently Asked Questions (FAQ)

Q1: What essential criteria must be matched when substituting RFX10TF6S with alternate diodes or rectifiers?
A1: Substitution requires exact correspondence in maximum reverse voltage, average rectified current, maximum forward voltage at rated current, reverse recovery time, reverse leakage current, mechanical package, mounting style, and environmental compliance (RoHS, REACH, MSL).

Q2: Are all listed substitute parts form-fit-function compatible for through-hole TO-220 applications?
A2: All listed substitutes use through-hole mounting and TO-220-derived packages. Physical footprint variation may exist in tab isolation or full pack/isolated tab versions—details are provided for direct pin compatibility.

Q3: How does RoHS or REACH compliance factor into substitute selection?
A3: Only parts that are specifically stated as RoHS and REACH compliant are included to adhere to regulatory and environmental requirements in applicable markets.

Q4: Can substituting with a part of different average rectified current result in functional differences?
A4: Substitution with a higher current-rated device is designed to meet or exceed the main part's current handling without compromising function, as long as all other electrical and mechanical parameters match per section guidelines.

Q5: Is MSL (Moisture Sensitivity Level) relevant in through-hole rectifier replacement?
A5: MSL is provided for full compliance. All listed devices meet MSL 1 or are marked not applicable for through-hole devices, aligning with the requirements specified in the main part.
