Key Parameters

Substitute Part Grouping Explanation

Substitution of the FES16CT is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Voltage - DC Reverse (Vr) (Max): 150V
• Current - Average Rectified (Io): 16A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 35 ns
• Current - Reverse Leakage @ Vr: 10 µA @ 150V
• Operating Temperature - Junction: -65°C to 150°C

Mechanical Equivalence Criteria:

• Mounting Type: Through Hole
• Package / Case: TO-220-2

The substitute part FES16CT-E3/45 meets all specified electrical parameters and maintains identical mechanical compatibility through the TO-220-2 package designation. Both components are classified as Standard technology rectifier diodes with matching thermal and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FES16CT-E3/45 manufactured by Vishay General Semiconductor - Diodes Division is a direct functional equivalent for the obsolete FES16CT. Selection of this substitute part is supported by the following factors:

Electrical Compatibility: All critical electrical parameters match or exceed the original specification, including reverse voltage rating, average rectified current capacity, reverse recovery time, and reverse leakage current. Forward voltage characteristics remain within acceptable operating margins.

Mechanical Compatibility: Both components utilize identical Through Hole mounting and TO-220-2 package configurations, ensuring direct board-level substitution without layout modifications.

Product Status: The FES16CT-E3/45 maintains Active product status with current manufacturing availability, addressing the obsolescence of the original FES16CT. Current inventory of 860 pieces is available.

Compliance and Certifications: The FES16CT-E3/45 is ROHS3 Compliant and maintains REACH Unaffected status, consistent with the original part's regulatory classification. Both components share identical ECCN (EAR99) and HTSUS (8541.10.0080) designations.

Thermal Performance: Operating temperature range remains -65°C to 150°C, maintaining full thermal compatibility across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the FES16CT-E3/45 be used as a direct replacement for the FES16CT?

A: Yes. The FES16CT-E3/45 meets all electrical and mechanical specifications of the FES16CT. Both components share identical voltage ratings (150V), current ratings (16A), reverse recovery time (35 ns), and package configuration (TO-220-2 Through Hole). Direct substitution is supported without circuit modification.

Q: What is the difference between the TO-220-2 and TO-220AC package designations listed for the substitute part?

A: The Package / Case specification for both components is TO-220-2. The Supplier Device Package designation of TO-220AC for the FES16CT-E3/45 refers to the manufacturer's internal packaging classification and does not affect electrical or mechanical compatibility. The functional package remains TO-220-2.

Q: Are there any thermal or performance differences between the FES16CT and FES16CT-E3/45?

A: No thermal or performance differences exist within the specified parameters. Both components operate across -65°C to 150°C, feature identical reverse recovery time (35 ns), and maintain the same reverse leakage current (10 µA @ 150V). Forward voltage characteristics are compatible across the rated current range.

Q: Why is the FES16CT classified as obsolete?

A: The FES16CT is listed as obsolete by the original manufacturer onsemi. The FES16CT-E3/45 from Vishay maintains Active product status and provides equivalent electrical and mechanical performance for ongoing design support.

Q: What compliance certifications apply to the FES16CT-E3/45?

A: The FES16CT-E3/45 is ROHS3 Compliant and REACH Unaffected. Both the original FES16CT and substitute share identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications.

Q: Is the FES16CT-E3/45 available in the same packaging format?

A: The FES16CT-E3/45 is supplied in Tube packaging, while original inventory status for the FES16CT is not specified. Both components utilize identical Through Hole TO-220-2 package configuration for board-level installation. Packaging format does not affect component functionality or compatibility.
