Substitute Part Grouping Explanation

Substitution of the SFT1350-TL-H is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

Drain-to-Source Voltage (Vdss): Must equal or exceed 40V
FET Type: Must be P-Channel
Technology: Must be MOSFET (Metal Oxide)
Gate Voltage Range (Vgs Max): Must accommodate ±20V
Package Type: Must be TO-252-3 (DPAK) surface mount

Current Rating Consideration: The SFT1350-TL-H provides 19A continuous drain current. Substitute parts with lower current ratings (7.2A and 6.6A) operate within the same voltage class and package but with reduced current capacity. These substitutes are applicable only in applications where the actual circuit current demand does not exceed the substitute part's rated continuous drain current.

Thermal and Switching Characteristics: On-resistance, gate charge, and input capacitance values are provided for each part. These parameters influence switching speed, power dissipation, and thermal performance but do not preclude substitution when electrical ratings are met.

Engineering Selection Recommendations

Primary Substitutes (Active Status):

All three substitute parts—DMP4051LK3-13, DMP4051LK3Q-13, and ZXMP4A16KTC—are manufactured by Diodes Incorporated and carry active product status. Each meets the electrical requirements for voltage class (40V Vdss), FET type (P-Channel), technology (MOSFET), and package configuration (TO-252-3 DPAK surface mount).

Compliance and Certification:

DMP4051LK3-13 and ZXMP4A16KTC are available in standard commercial packaging (Cut Tape and Tape & Reel). DMP4051LK3Q-13 is qualified to AEC-Q101 automotive standards and is supplied in Tape & Reel packaging, making it suitable for applications requiring automotive-grade components.

All substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Current Rating Consideration:

The substitute parts provide reduced continuous drain current ratings (7.2A for DMP4051 variants, 6.6A for ZXMP4A16KTC) compared to the SFT1350-TL-H (19A). Selection of a substitute part must be based on the actual circuit current requirements. If the application circuit operates at or below the substitute part's rated continuous drain current, the part is electrically suitable. If circuit current exceeds the substitute part's rating, alternative solutions must be evaluated.

Thermal Performance:

The substitute parts provide comparable or superior on-resistance characteristics (51–60 mOhm versus 59 mOhm for the main part), which influences thermal performance. Gate charge and input capacitance values are slightly elevated in the substitute parts, affecting switching speed and drive requirements.

Inventory and Availability:

DMP4051LK3-13 (72,800 pcs), ZXMP4A16KTC (24,100 pcs), and DMP4051LK3Q-13 (2,400 pcs) are in stock. The SFT1350-TL-H (167,000 pcs) remains available as an obsolete part.

Frequently Asked Questions (FAQ)

Q: Can DMP4051LK3-13, DMP4051LK3Q-13, and ZXMP4A16KTC be used interchangeably with the SFT1350-TL-H?

A: These parts share identical voltage ratings (40V Vdss), FET type (P-Channel), technology (MOSFET), and package configuration (TO-252-3 DPAK). They are electrically compatible at the pin level. However, the substitute parts have lower continuous drain current ratings (7.2A and 6.6A versus 19A). Interchangeability depends on whether the circuit current demand does not exceed the substitute part's rating.

Q: What is the difference between DMP4051LK3-13 and DMP4051LK3Q-13?

A: Both parts have identical electrical specifications (40V, 7.2A, 51 mOhm Rds On). DMP4051LK3Q-13 is qualified to AEC-Q101 automotive standards and is supplied in Tape & Reel packaging. DMP4051LK3-13 is available in Cut Tape and Digi-Reel packaging. Selection depends on application requirements and packaging preferences.

Q: How do the gate charge and input capacitance differences affect circuit design?

A: The SFT1350-TL-H has lower gate charge (12 nC) and input capacitance (590 pF) compared to the substitute parts. DMP4051 variants have 14 nC gate charge and 674 pF capacitance; ZXMP4A16KTC has 29.6 nC gate charge and 965 pF capacitance. These differences affect gate drive requirements and switching speed. Higher values require stronger gate drive circuits and may increase switching losses. Circuit validation is necessary if gate drive circuits are marginal.

Q: Are all substitute parts RoHS and REACH compliant?

A: All substitute parts are ROHS3 compliant and REACH unaffected. The SFT1350-TL-H compliance status is not specified in the provided data. Substitute parts meet current environmental and regulatory requirements for new designs.

Q: What is the operating temperature range for each part?

A: The SFT1350-TL-H is rated to 150°C junction temperature (TJ). All substitute parts are rated from -55°C to 150°C TJ, providing a wider operating range. This does not preclude substitution; the substitute parts simply offer extended low-temperature capability.

Q: Can I use a substitute part with lower current rating in a high-current application?

A: No. The substitute parts are rated for 7.2A (DMP4051 variants) or 6.6A (ZXMP4A16KTC) continuous drain current. If the circuit requires 19A or higher current, these substitutes are not suitable. The circuit must operate within the substitute part's rated current to prevent thermal stress and device failure.

Q: What packaging options are available for each substitute part?

A: DMP4051LK3-13 is supplied in Cut Tape (CT) and Digi-Reel packaging. DMP4051LK3Q-13 is supplied in Tape & Reel (TR). ZXMP4A16KTC is supplied in Tape & Reel (TR). All parts use TO-252-3 (DPAK) surface mount package configuration, ensuring mechanical compatibility with the SFT1350-TL-H footprint.
