Key Parameters

Substitute Part Grouping Explanation

Substitution of the DMP4025LSDQ-13 is determined by equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Drain to Source Voltage (Vdss): 40V minimum
• Configuration: Dual P-Channel MOSFET array
• Operating Temperature Range: -55°C to 150°C minimum
• Package Type: 8-SOIC surface mount form factor with 0.154" (3.90mm) width

Regulatory & Compliance Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status
• Active product status

The SI4909DY-T1-GE3 manufactured by Vishay Siliconix meets all substitution criteria. This part maintains identical voltage rating, dual P-channel configuration, compatible 8-SOIC package dimensions, and equivalent regulatory compliance. The substitute part demonstrates enhanced current capability (8A versus 5.8A) and higher power dissipation rating (3.2W versus 1.25W), positioning it as a direct functional replacement with performance margin.

Engineering Selection Recommendations

Primary Selection: DMP4025LSDQ-13

The DMP4025LSDQ-13 remains the primary component choice when original manufacturer specification and AEC-Q101 automotive qualification are required. This part is Active status with 2600 units in stock inventory.

Substitute Selection: SI4909DY-T1-GE3

The SI4909DY-T1-GE3 is a qualified substitute when:

• Equivalent 40V voltage rating and dual P-channel configuration are required
• Surface mount 8-SOIC package compatibility is maintained
• RoHS3 and MSL Level 1 compliance requirements are satisfied
• Active product status and continuous availability are necessary

The SI4909DY-T1-GE3 provides enhanced electrical performance with 8A continuous drain current (versus 5.8A) and 3.2W maximum power dissipation (versus 1.25W). This substitute carries higher gate charge (63nC versus 33.7nC) and input capacitance (2000pF versus 1640pF) specifications. The substitute part is available with 4532 units in stock inventory.

Both parts maintain identical operating temperature range (-55°C to 150°C), identical package dimensions, and equivalent regulatory compliance status. Selection between these parts is determined by application-specific current and power requirements, inventory availability, and original design qualification constraints.

Frequently Asked Questions (FAQ)

Q: Can the SI4909DY-T1-GE3 directly replace the DMP4025LSDQ-13 in existing designs?

A: The SI4909DY-T1-GE3 is mechanically and electrically compatible as a substitute. Both parts feature identical 8-SOIC package dimensions (0.154", 3.90mm width), dual P-channel configuration, and 40V voltage rating. Pin-to-pin compatibility is maintained. However, design validation is required to confirm that the higher gate charge (63nC versus 33.7nC) and input capacitance (2000pF versus 1640pF) do not impact circuit timing or switching performance in the target application.

Q: What are the key electrical differences between these two parts?

A: The SI4909DY-T1-GE3 provides higher continuous drain current (8A versus 5.8A) and greater power dissipation capability (3.2W versus 1.25W). The DMP4025LSDQ-13 features lower gate charge (33.7nC versus 63nC) and lower input capacitance (1640pF versus 2000pF), which may provide advantages in high-frequency switching applications. Both parts maintain identical 40V voltage rating and -55°C to 150°C operating temperature range.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DMP4025LSDQ-13 and SI4909DY-T1-GE3 are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited). Both parts carry REACH Unaffected status.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (Small Outline Integrated Circuit) package is a surface mount form factor with standardized 0.154" (3.90mm) width. Both substitute parts use this identical package type, ensuring mechanical compatibility with existing printed circuit board layouts and assembly processes. No PCB redesign is required for package substitution.

Q: How do gate charge specifications affect circuit design?

A: Gate charge (Qg) determines the amount of charge required to switch the MOSFET on or off. The DMP4025LSDQ-13 requires 33.7nC at 10V, while the SI4909DY-T1-GE3 requires 63nC at 10V. Higher gate charge increases switching time and power dissipation in the gate drive circuit. Applications with tight switching frequency requirements or limited gate drive current capacity may require circuit analysis to confirm compatibility with the substitute part's higher gate charge specification.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. These parts can be stored indefinitely without desiccant packaging and do not require baking before reflow soldering. This classification simplifies inventory management and assembly processes.

Q: Are there any temperature operating range differences?

A: No. Both the DMP4025LSDQ-13 and SI4909DY-T1-GE3 operate across identical temperature ranges: -55°C to 150°C (TJ). Temperature performance is equivalent between these parts.
