Substitute Part Grouping Explanation

Substitution of the RJK5014DPP-E0#T2 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss) rating must equal or exceed 500V
• Continuous drain current (Id) must meet or exceed 19A at 25°C
• On-state resistance (Rds On) must not significantly degrade circuit performance
• Gate charge (Qg) and input capacitance (Ciss) must be compatible with existing gate drive circuitry
• Maximum junction temperature rating of 150°C or higher
• Through-hole mounting configuration with TO-220 package family compatibility

Identified Substitute Parts:

1. FDPF20N50FT (onsemi) — Meets voltage and current requirements with improved on-state resistance and active product status
2. TK14A55D(STA4,Q,M) (Toshiba Semiconductor and Storage) — Exceeds voltage rating with comparable current handling and active product status

Both substitute parts maintain N-Channel MOSFET technology, through-hole mounting, and TO-220 package family compatibility while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

FDPF20N50FT (onsemi UniFET™ Series)

The FDPF20N50FT is the primary substitute for the RJK5014DPP-E0#T2. This part maintains identical 500V voltage rating and exceeds the 19A current requirement with 20A continuous drain current. The on-state resistance is improved at 260mOhm compared to 390mOhm, resulting in lower power dissipation and improved thermal performance. The FDPF20N50FT carries active product status with 20,360 units in stock, ensuring long-term availability. Both devices are ROHS3 compliant and carry EAR99 classification. The TO-220F-3 package is mechanically compatible with TO-220FP footprints in through-hole applications.

TK14A55D(STA4,Q,M) (Toshiba π-MOSVII Series)

The TK14A55D(STA4,Q,M) serves as an alternative substitute with a higher 550V voltage rating, providing additional design margin for overvoltage conditions. Continuous drain current is rated at 14A, which is lower than the original 19A specification but remains suitable for applications where the full 19A is not required. On-state resistance of 370mOhm is comparable to the original part. Gate charge is optimized at 40nC, lower than both the original and FDPF20N50FT, reducing gate drive power requirements. The TK14A55D(STA4,Q,M) is active with 872 units in stock and maintains ROHS3 compliance and EAR99 classification. The TO-220SIS package is mechanically compatible with TO-220 through-hole applications.

Selection Criteria:

• Select FDPF20N50FT when full 19A+ current capacity and improved on-state resistance are required
• Select TK14A55D(STA4,Q,M) when higher voltage margin (550V) and lower gate charge are beneficial, and continuous current requirements are 14A or less
• Both substitutes support identical gate voltage (±30V) and maximum junction temperature (150°C) specifications
• All three parts maintain through-hole mounting and TO-220 package family compatibility

Frequently Asked Questions (FAQ)

Q: Can the FDPF20N50FT directly replace the RJK5014DPP-E0#T2 in existing PCB designs?

A: The FDPF20N50FT is mechanically and electrically compatible with the RJK5014DPP-E0#T2 in through-hole TO-220 applications. Both devices share identical 500V voltage rating, ±30V gate voltage range, and 150°C maximum junction temperature. The FDPF20N50FT provides 20A continuous current versus 19A, and improved on-state resistance of 260mOhm versus 390mOhm. The TO-220F-3 package footprint is compatible with TO-220FP mounting. No circuit modifications are required for substitution.

Q: What are the key differences between the FDPF20N50FT and TK14A55D(STA4,Q,M)?

A: The FDPF20N50FT maintains the 500V voltage rating of the original part with 20A current capacity and 260mOhm on-state resistance. The TK14A55D(STA4,Q,M) provides a higher 550V voltage rating with 14A current capacity and 370mOhm on-state resistance. Gate charge differs significantly: FDPF20N50FT at 65nC versus TK14A55D(STA4,Q,M) at 40nC. Input capacitance is higher in the FDPF20N50FT at 3390pF versus 2300pF. Select based on whether your application requires the full 19A+ current (FDPF20N50FT) or benefits from higher voltage margin and lower gate charge (TK14A55D).

Q: Are there package compatibility concerns when substituting these parts?

A: All three parts use through-hole TO-220 package variants: the original uses TO-220FP, FDPF20N50FT uses TO-220F-3, and TK14A55D(STA4,Q,M) uses TO-220SIS. These package variants share identical pin configurations and mounting hole spacing, making them mechanically interchangeable in standard TO-220 through-hole PCB layouts. No PCB redesign is necessary.

Q: What is the impact of higher input capacitance in the FDPF20N50FT?

A: The FDPF20N50FT has input capacitance (Ciss) of 3390pF at 25V compared to 1800pF in the original RJK5014DPP-E0#T2. Higher input capacitance increases gate charge requirements and may increase switching losses in high-frequency applications. Gate drive circuitry must supply sufficient current to charge this capacitance within the required switching time. Verify that existing gate drive circuits can accommodate the 65nC gate charge specification of the FDPF20N50FT.

Q: Which substitute part offers the best thermal performance?

A: The FDPF20N50FT provides the best thermal performance with the lowest on-state resistance of 260mOhm at 10A, 10V, compared to 390mOhm in the original and 370mOhm in the TK14A55D(STA4,Q,M). Lower on-state resistance reduces conduction losses and heat generation. The FDPF20N50FT also has the highest power dissipation rating at 38.5W. For applications prioritizing thermal efficiency, the FDPF20N50FT is the optimal choice.

Q: Are all substitute parts compliant with current regulatory standards?

A: Both substitute parts are ROHS3 compliant and carry EAR99 export classification, matching the compliance profile of the original RJK5014DPP-E0#T2. The FDPF20N50FT is REACH unaffected, while the TK14A55D(STA4,Q,M) is REACH affected. Both parts maintain identical HTSUS classification (8541.29.0095). Verify REACH compliance requirements for your specific application and end-use region.

Q: What is the availability status of these substitute parts?

A: The FDPF20N50FT has 20,360 units in stock with active product status, ensuring long-term availability and supply chain stability. The TK14A55D(STA4,Q,M) has 872 units in stock and active product status. The original RJK5014DPP-E0#T2 is obsolete with 1,058 units remaining in stock. For new designs and long-term support, the FDPF20N50FT is the recommended choice due to superior availability and active manufacturer support.
