Key Parameters

Substitute Part Grouping Explanation

Substitution of the FEP16DT is determined by strict equivalence across the following critical parameters: diode configuration (1 Pair Common Cathode), reverse voltage rating (200 V maximum), average rectified current per diode (16 A), forward voltage characteristics (950 mV @ 8 A), fast recovery speed classification (≤ 500ns, > 200mA), reverse recovery time (35 ns), reverse leakage current (10 µA @ 200 V), operating junction temperature range (-55°C to 150°C), and through-hole mounting in TO-220-3 package.

Substitute parts are classified into two categories:

Direct Manufacturer Equivalent: FEP16DT-E3/45 matches all electrical and mechanical parameters identically to the main part, with active product status and RoHS3 compliance.

Parametric Equivalent: ER1602CT_T0_00001 maintains identical electrical specifications and package configuration, with active product status and RoHS3 compliance.

Similar Substitute: STTH1602CT provides functional substitution with the same diode configuration, reverse voltage rating, and package type, but operates at reduced average rectified current (10 A per diode) and exhibits different forward voltage and reverse recovery characteristics.

Parameter Comparison

Engineering Selection Recommendations

FEP16DT-E3/45 is the primary direct equivalent for FEP16DT replacement. This part maintains identical electrical specifications across all critical parameters including 16 A average rectified current, 950 mV forward voltage at 8 A, and 35 ns reverse recovery time. The device carries active product status and RoHS3 compliance certification, supporting modern procurement and environmental regulatory requirements.

ER1602CT_T0_00001 provides parametric equivalence with identical electrical performance and active product status. This part demonstrates superior reverse leakage characteristics (1 µA @ 200 V versus 10 µA @ 200 V) and carries RoHS3 compliance. The operating temperature range extends to -50°C minimum, which is acceptable for applications requiring -55°C operation only at the lower boundary.

STTH1602CT functions as a similar substitute for applications where 10 A average rectified current per diode is acceptable. This part exhibits superior reverse recovery time (26 ns versus 35 ns) and lower reverse leakage current (6 µA @ 200 V). However, the reduced current rating and elevated forward voltage (1.1 V @ 8 A) require circuit-level evaluation. The maximum junction temperature of 175°C provides extended thermal headroom compared to the 150°C maximum of the main part.

All substitute parts maintain TO-220-3 through-hole packaging, 200 V reverse voltage rating, fast recovery speed classification, and REACH compliance status, ensuring mechanical and regulatory compatibility with the original FEP16DT design.

Frequently Asked Questions (FAQ)

Q: Can FEP16DT-E3/45 be used as a direct replacement for FEP16DT?

A: Yes. FEP16DT-E3/45 is a direct manufacturer equivalent with identical electrical specifications, diode configuration, package type, and operating temperature range. The part carries active product status and RoHS3 compliance.

Q: What is the primary difference between FEP16DT and STTH1602CT?

A: The STTH1602CT operates at 10 A average rectified current per diode, compared to 16 A for FEP16DT. Additionally, STTH1602CT exhibits higher forward voltage (1.1 V @ 8 A versus 950 mV @ 8 A) and faster reverse recovery time (26 ns versus 35 ns). These differences require circuit-level analysis to determine suitability for specific applications.

Q: Are all substitute parts available in the same TO-220-3 package?

A: Yes. FEP16DT-E3/45, STTH1602CT, and ER1602CT_T0_00001 are all packaged in TO-220-3 through-hole configuration, ensuring mechanical compatibility with existing PCB layouts and thermal management designs.

Q: Which substitute part has the lowest reverse leakage current?

A: ER1602CT_T0_00001 exhibits the lowest reverse leakage current at 1 µA @ 200 V, compared to 10 µA @ 200 V for FEP16DT and FEP16DT-E3/45, and 6 µA @ 200 V for STTH1602CT.

Q: Do all substitute parts meet RoHS3 compliance?

A: FEP16DT-E3/45, STTH1602CT, and ER1602CT_T0_00001 all carry RoHS3 compliance certification. The original FEP16DT does not specify RoHS status.

Q: What is the operating temperature range difference between ER1602CT_T0_00001 and FEP16DT?

A: ER1602CT_T0_00001 operates from -50°C to 150°C, while FEP16DT operates from -55°C to 150°C. The 5°C difference at the lower boundary may be significant for applications requiring full -55°C operation.

Q: Can STTH1602CT be used in high-current applications designed for FEP16DT?

A: STTH1602CT is rated for 10 A average rectified current per diode, compared to 16 A for FEP16DT. Applications requiring the full 16 A rating must use FEP16DT-E3/45 or ER1602CT_T0_00001 to maintain design specifications.
