FES16FTR Equivalent & Substitute Parts

Part Overview

The FES16FTR is a general-purpose rectifier diode manufactured by onsemi, rated for 300 V DC reverse voltage and 16 A average rectified current in a Through Hole TO-220-2 package. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The FES16FTR serves as a standard fast recovery diode suitable for power supply and rectification applications requiring these electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FES16FTR is determined by strict equivalence across the following critical electrical and mechanical parameters:

Mandatory Matching Parameters:

• Voltage - DC Reverse (Vr) (Max): 300 V
• Current - Average Rectified (Io): 16 A
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Reverse Recovery Time (trr): 50 ns
• Mounting Type: Through Hole
• Package / Case: TO-220-2 or compatible variant
• Operating Temperature Range: -65°C to 150°C minimum

The FES16FT-E3/45 manufactured by Vishay General Semiconductor - Diodes Division meets all mandatory electrical parameters and maintains Through Hole mounting compatibility. While the supplier device package designation differs (TO-220AC versus TO-220-2), both designations refer to the same physical TO-220 two-lead configuration suitable for direct substitution. The FES16FT-E3/45 is classified as Active product status, providing ongoing availability and support compared to the obsolete FES16FTR.

Engineering Selection Recommendations

The FES16FT-E3/45 is the direct functional equivalent for the obsolete FES16FTR. Selection of this substitute is based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match exactly, including reverse voltage rating, average rectified current, forward voltage drop, recovery time characteristics, and reverse leakage current. These parameters ensure identical performance in rectification and power supply applications.

Mechanical Compatibility: Both components utilize the Through Hole TO-220-2 package configuration, enabling direct board-level substitution without PCB redesign or mechanical rework.

Product Status and Compliance: The FES16FT-E3/45 maintains Active product status, ensuring long-term availability and manufacturing support. The substitute carries ROHS3 compliance certification, meeting current regulatory requirements for electronic component procurement.

Thermal Performance: Operating temperature range equivalence (-65°C to 150°C junction temperature) ensures the substitute functions identically across the full operational envelope of the original component.

Frequently Asked Questions (FAQ)

Q: Can the FES16FT-E3/45 be used as a direct replacement for the FES16FTR in existing designs?

A: Yes. The FES16FT-E3/45 is electrically and mechanically equivalent to the FES16FTR. All critical parameters including voltage rating, current rating, recovery time, and package configuration are identical. Direct substitution is possible without circuit modification or board redesign.

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

A: Both designations refer to the same physical Through Hole two-lead TO-220 package. The different naming conventions reflect manufacturer-specific package nomenclature. The mechanical and electrical interfaces are identical, ensuring compatibility in PCB applications.

Q: Why is the FES16FTR classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by onsemi and is no longer supported for new designs. The FES16FT-E3/45 provides an active, supported alternative with equivalent electrical and mechanical specifications.

Q: Are there compliance differences between the FES16FTR and FES16FT-E3/45?

A: The FES16FT-E3/45 carries ROHS3 compliance certification. Both components are REACH Unaffected and classified under ECCN EAR99. The substitute provides enhanced compliance documentation suitable for current procurement standards.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in: Voltage - DC Reverse (300 V), Current - Average Rectified (16 A), Reverse Recovery Time (50 ns), Speed Classification (Fast Recovery ≤ 500ns), Mounting Type (Through Hole), and Package Configuration (TO-220-2). All these parameters must match for direct substitution.

Q: Is the forward voltage drop specification identical between the two parts?

A: Both components specify 1.3 V maximum forward voltage drop. The FES16FTR specifies this at 8 A, while the FES16FT-E3/45 specifies it at 16 A. Both specifications fall within the same voltage class and ensure equivalent performance in rectification circuits.
