Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMG3418L-13 is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Drain-to-Source Voltage (Vdss): 30V minimum
• Continuous Drain Current (Id): 4A minimum at 25°C
• Gate Threshold Voltage (Vgs(th)): Compatible with 1.5V @ 250µA
• On-State Resistance (Rds On): 60 mOhm or lower @ 4A, 10V
• Package: SOT-23-3 surface mount configuration
• Operating Temperature: -55°C to 150°C minimum
• Compliance: ROHS3 compliant

Parametric Equivalent Classification: The DMG3418L-7 is a parametric equivalent manufactured by Diodes Incorporated. It maintains identical electrical specifications and package configuration, with the primary difference being packaging format (Cut Tape & Digi-Reel® versus Tape & Reel).

Manufacturer Recommended Substitute Classification: The SI2304-TP is a manufacturer-recommended substitute from Micro Commercial Co. This part operates within the same voltage class (30V) and package family (SOT-23), but with reduced continuous drain current (2.5A) and lower power dissipation (250mW). This substitute is applicable only in applications where the 2.5A current rating is sufficient.

Parameter Comparison

Engineering Selection Recommendations

DMG3418L-7 (Parametric Equivalent): The DMG3418L-7 is a direct parametric equivalent to the DMG3418L-13. Both parts are manufactured by Diodes Incorporated and maintain identical electrical specifications across all critical parameters including Vdss, Id, Rds On, Vgs(th), and power dissipation. The parts are functionally interchangeable in all applications. The primary distinction is packaging format: DMG3418L-7 is supplied in Cut Tape & Digi-Reel® format, while DMG3418L-13 is supplied in standard Tape & Reel format. Both parts are Active status and ROHS3 compliant with MSL 1 rating.

SI2304-TP (Manufacturer Recommended Substitute): The SI2304-TP is a manufacturer-recommended substitute suitable for applications where the reduced continuous drain current specification (2.5A versus 4A) is acceptable. This part maintains the 30V Vdss rating and operates within the same temperature range. However, the SI2304-TP exhibits higher gate threshold voltage (3V versus 1.5V), higher on-state resistance (90 mOhm @ 2.2A, 4.5V), and significantly lower power dissipation capability (250mW versus 1.4W). The SI2304-TP is Active status and ROHS3 compliant with MSL 1 rating. Selection of this substitute requires confirmation that application current requirements do not exceed 2.5A continuous drain current.

Frequently Asked Questions (FAQ)

Q: Can DMG3418L-7 be used as a direct replacement for DMG3418L-13?

A: Yes. The DMG3418L-7 is a parametric equivalent with identical electrical specifications. Both parts are N-Channel MOSFETs rated for 30V, 4A continuous drain current, with 60 mOhm on-state resistance and 1.5V gate threshold voltage. The parts are functionally interchangeable. The difference is packaging format only: DMG3418L-7 is supplied in Cut Tape & Digi-Reel® while DMG3418L-13 is supplied in standard Tape & Reel.

Q: Under what conditions can SI2304-TP be substituted for DMG3418L-13?

A: The SI2304-TP can be substituted only in applications where the continuous drain current requirement does not exceed 2.5A. The SI2304-TP is rated for 2.5A maximum continuous drain current compared to 4A for the DMG3418L-13. Both parts maintain 30V Vdss rating and operate across the same temperature range. Applications requiring higher current capacity or lower on-state resistance must use DMG3418L-13 or DMG3418L-7.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The DMG3418L-13, DMG3418L-7, and SI2304-TP are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Both are surface mount packaging formats suitable for automated assembly. Tape & Reel (TR) is standard continuous reel packaging. Cut Tape & Digi-Reel® is a format where tape is cut into smaller segments for reduced minimum order quantities and improved inventory management. The electrical and mechanical specifications of the component remain identical regardless of packaging format.

Q: Does the SI2304-TP have different gate drive requirements?

A: Yes. The SI2304-TP has a higher gate threshold voltage (Vgs(th)) of 3V @ 250µA compared to 1.5V for the DMG3418L-13. Additionally, the SI2304-TP requires 10V gate charge specification versus 4.5V for the DMG3418L-13. Gate drive circuits must be verified for compatibility with these higher threshold voltage requirements.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: The DMG3418L-13 and DMG3418L-7 are interchangeable in high-frequency applications due to identical gate charge (5.5 nC @ 4.5V) and input capacitance (464.3 pF @ 15V). The SI2304-TP exhibits higher gate charge (10 nC @ 10V) and lower input capacitance (240 pF @ 15V), which may affect switching performance and should be evaluated for specific frequency requirements.
