Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Mandatory Matching Criteria:

• Drain to Source Voltage (Vdss): 30V minimum
• Package Type: SOT-23-3 surface mount configuration
• FET Type: P-Channel
• Technology: MOSFET (Metal Oxide)
• Operating Temperature Range: -55°C to 150°C minimum
• RoHS3 Compliance and MSL 1 rating

Performance Compatibility Criteria:

• Continuous Drain Current (Id): Equal to or greater than 3.3A
• On-Resistance (Rds On): Lower or equivalent values ensure thermal performance
• Gate Threshold Voltage (Vgs(th)): Within compatible drive voltage ranges
• Power Dissipation: Sufficient thermal capability for application requirements

Substitute parts are grouped into two categories: Parametric Equivalents (identical electrical specifications) and Manufacturer Recommended Alternatives (functionally compatible with minor parameter variations within acceptable operating margins).

Parameter Comparison

Engineering Selection Recommendations

DMP3068L-7 (Diodes Incorporated)

This part is a parametric equivalent to the DMP3068L-13, offering identical electrical specifications across all measured parameters. Both devices share the same base product number (DMP3068) and differ only in packaging designation. The DMP3068L-7 is suitable for direct substitution in all applications where the DMP3068L-13 is specified. Both parts maintain Active product status, ROHS3 compliance, and MSL 1 rating. Inventory availability is significantly higher for the DMP3068L-7 (65,300 units versus 730 units).

PJA3401A_R1_00001 (Panjit International Inc.)

This part exceeds the DMP3068L-13 in continuous drain current (3.6A versus 3.3A) and on-resistance performance (54mOhm versus 72mOhm at rated conditions). Power dissipation capability is higher at 1.25W. The gate threshold voltage matches at 1.3V, enabling compatible drive circuitry. This part is suitable for applications requiring enhanced current handling or thermal margin. All compliance certifications (ROHS3, MSL 1) are maintained. Gate charge is slightly elevated at 19nC, which may affect switching speed in high-frequency applications.

SI2307BDS-T1-GE3 (Vishay Siliconix)

This part operates within acceptable parameters for applications where continuous drain current requirements do not exceed 2.5A. The on-resistance of 78mOhm is comparable to the DMP3068L-13 at its rated current. Gate threshold voltage is elevated to 3.0V, requiring higher drive voltage levels. Power dissipation at 750mW is marginally higher. This part is suitable for lower-current applications or where Vishay device qualification is required. All compliance certifications are maintained.

FDN360P (onsemi)

This part is suitable only for applications where continuous drain current does not exceed 2.0A. The reduced current rating and lower power dissipation (500mW) indicate this device is intended for lower-power circuit implementations. Gate threshold voltage is elevated to 3.0V. On-resistance at 80mOhm is acceptable for the reduced current specification. This part is not recommended for direct substitution in circuits designed for the full 3.3A rating of the DMP3068L-13. All compliance certifications are maintained.

Frequently Asked Questions (FAQ)

Q: Can DMP3068L-7 be used as a direct replacement for DMP3068L-13?

A: Yes. The DMP3068L-7 is a parametric equivalent with identical electrical and thermal specifications. Both parts share the same base product number and differ only in packaging designation. No circuit modifications are required.

Q: What is the primary difference between the DMP3068L-13 and PJA3401A_R1_00001?

A: The PJA3401A_R1_00001 offers higher continuous drain current (3.6A versus 3.3A) and superior on-resistance performance (54mOhm versus 72mOhm). Power dissipation capability is also higher at 1.25W. Gate threshold voltage remains compatible at 1.3V. This part is suitable for applications requiring enhanced current handling or thermal margin.

Q: Can FDN360P replace the DMP3068L-13 in all applications?

A: No. The FDN360P is rated for a maximum continuous drain current of 2.0A, which is below the DMP3068L-13 specification of 3.3A. This part is suitable only for applications where current requirements do not exceed 2.0A. Additionally, the gate threshold voltage is elevated to 3.0V, requiring higher drive voltage levels.

Q: Are all substitute parts available in the same package configuration?

A: All substitute parts are available in SOT-23-3 surface mount package, which is mechanically and electrically compatible with the DMP3068L-13. Pin assignments and footprints are identical, enabling direct PCB substitution without layout modifications.

Q: What compliance certifications apply to all listed substitute parts?

A: All substitute parts maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity) rating. All parts operate across the -55°C to 150°C temperature range. REACH status is unaffected for all parts, and all carry EAR99 export classification.

Q: How does gate threshold voltage affect substitution compatibility?

A: Gate threshold voltage (Vgs(th)) determines the minimum gate-source voltage required to turn the device on. The DMP3068L-13 and DMP3068L-7 both specify 1.3V, while PJA3401A_R1_00001 also specifies 1.3V. FDN360P and SI2307BDS-T1-GE3 specify 3.0V, requiring higher drive voltage levels. Circuits designed for 1.3V threshold devices may not fully activate devices with 3.0V thresholds using the same gate drive voltage.

Q: Which substitute part offers the best on-resistance performance?

A: The PJA3401A_R1_00001 offers the lowest on-resistance at 54mOhm when measured at 3.6A and 10V gate-source voltage. This results in lower power dissipation and reduced thermal generation compared to the DMP3068L-13 at equivalent current levels.

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

A: Gate charge (Qg) affects switching speed and power loss in high-frequency applications. The DMP3068L-13 specifies 15.9nC, while PJA3401A_R1_00001 specifies 19nC (higher), and FDN360P specifies 9nC (lower). For applications operating above 1MHz, gate charge differences may impact efficiency and thermal performance. Verify switching frequency requirements before substitution.

Q: What inventory considerations apply to these substitute parts?

A: DMP3068L-7 offers the highest inventory availability at 65,300 units. PJA3401A_R1_00001 has 7,180 units available. SI2307BDS-T1-GE3 has 23,157 units available. FDN360P has 50,100 units available. The original DMP3068L-13 has 730 units in stock. Inventory levels should be considered for long-term supply chain planning.
