Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSD223P L6327 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Drain to Source Voltage (Vdss): 20V
• Configuration: 2 P-Channel (Dual)
• Package / Case: SOT-363
• FET Feature: Logic Level Gate
• Mounting Type: Surface Mount
• Power - Max: 250mW

Allowable Parameter Variations:

• Current - Continuous Drain (Id): Substitute must equal or exceed 390mA
• Rds On (Max): Substitute must equal or be lower than 1.2 Ohm at rated conditions
• Operating Temperature Range: Substitute must encompass or exceed -55°C to 150°C

The DMP2004DWK-7 from Diodes Incorporated meets all mandatory matching parameters and demonstrates improved electrical performance characteristics within allowable variation limits.

Engineering Selection Recommendations

DMP2004DWK-7 as Primary Substitute:

The DMP2004DWK-7 is classified as an active product with ROHS3 compliance and REACH unaffected status. This substitute demonstrates electrical performance improvements over the obsolete BSD223P L6327, including lower on-resistance (0.9 Ohm versus 1.2 Ohm) and higher continuous drain current capability (430mA versus 390mA). The extended operating temperature range (-65°C to 150°C) provides additional thermal margin.

Both components share identical voltage ratings, power dissipation limits, package geometry, and logic-level gate configuration. The SOT-363 package footprint and pinout are directly compatible, enabling drop-in replacement without circuit board redesign.

The DMP2004DWK-7 is available in Tape & Reel packaging with substantial inventory levels, supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the DMP2004DWK-7 directly replace the BSD223P L6327 without circuit modifications?

A: Yes. Both components feature identical Vdss (20V), configuration (dual P-channel), package (SOT-363), and power rating (250mW). The DMP2004DWK-7 provides equal or superior electrical performance across all critical parameters. No circuit modifications are required for direct substitution.

Q: What is the significance of the lower Rds On value in the DMP2004DWK-7?

A: The DMP2004DWK-7 exhibits lower on-resistance (0.9 Ohm versus 1.2 Ohm) at comparable gate voltage and current levels. This results in reduced power dissipation during conduction, improved switching efficiency, and lower thermal stress on the component and surrounding circuitry.

Q: Are there package compatibility concerns between these components?

A: No. Both the BSD223P L6327 and DMP2004DWK-7 utilize the SOT-363 package (also designated as 6-VSSOP or 6-TSSOP). The physical footprint, lead spacing, and pinout are compatible, enabling direct board-level substitution.

Q: What is the product status difference between these parts?

A: The BSD223P L6327 is classified as obsolete, indicating discontinued manufacturing and limited availability. The DMP2004DWK-7 is classified as active, ensuring ongoing production, supply availability, and manufacturer support for technical documentation and quality assurance.

Q: Does the DMP2004DWK-7 meet the same compliance standards?

A: Both components are REACH unaffected and assigned EAR99 export classification. The DMP2004DWK-7 carries ROHS3 compliance certification. Both components have MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the impact of the extended temperature range in the DMP2004DWK-7?

A: The DMP2004DWK-7 operates from -65°C to 150°C, compared to -55°C to 150°C for the BSD223P L6327. This 10°C extension at the lower temperature limit provides additional operational margin for applications in extreme cold environments or with stringent thermal specifications.
