Key Parameters

Substitute Part Grouping Explanation

The equivalent and substitute part RFUH20TB4SNZC9 is identified strictly based on following parameters:

• Voltage - DC Reverse (Vr) (Max)
• Current - Average Rectified (Io)
• Voltage - Forward (Vf) (Max) @ If
• Speed (Reverse Recovery Time)
• Current - Reverse Leakage @ Vr
• Mounting Type
• Package / Case
• RoHS Status
• Moisture Sensitivity Level (MSL)
• REACH Status
• ECCN

All selection criteria are matched according to these parameters, ensuring that electrical performance, mounting, package type, and compliance status are equivalent or within specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RF2001T4S and RFUH20TB4SNZC9 are active, RoHS3 compliant, REACH unaffected, and have a Moisture Sensitivity Level (MSL) of 1, meeting unrestricted use requirements. Both devices meet EAR99 ECCN classification, suitable for most global commercial applications. Product replacement based on these attributes is valid for maintaining process and compliance standards, provided specified electrical and mechanical parameters are observed.

Frequently Asked Questions (FAQ)

Q1: What parameters are used to determine equivalency or substitution for diodes, rectifiers like RF2001T4S?
A1: Substitution is based on Voltage - DC Reverse (Vr) (Max), Average Rectified Current (Io), Forward Voltage (Vf), Reverse Recovery Time (trr), Reverse Leakage Current, mounting type, package/case, environmental compliance (RoHS, REACH), and ECCN.

Q2: Are the RF2001T4S and RFUH20TB4SNZC9 compatible in terms of electrical characteristics?
A2: Both models match in rated current, have similar reverse and forward voltage ratings, comparable reverse recovery times, and equivalent speed classifications as defined.

Q3: What is the significance of package and mounting differences?
A3: RF2001T4S uses a TO-220-3 Full Pack, while RFUH20TB4SNZC9 uses a TO-220-2 Full Pack. Both are through-hole and full-pack types; comparison should ensure mechanical layout compatibility based on these formats.

Q4: How does compliance status affect substitution?
A4: Both parts are RoHS3 compliant, REACH unaffected, and have MSL 1, ensuring global environmental and manufacturing process compliance.

Q5: Are there differences in product status or inventory that impact substitution?
A5: Both diodes are in active production status. It is essential to monitor inventory for timely procurement within engineering requirements.
