Key Parameters

Substitute Part Grouping Explanation

Substitution of the BSD223P is determined by strict equivalence across the following critical parameters:

Mandatory Matching Criteria:

• Dual P-channel MOSFET configuration
• Drain-source voltage rating of 20V or greater
• Continuous drain current rating of 390mA or greater per channel
• Logic level gate operation
• SOT-363 package compatibility
• Surface mount technology
• Maximum power dissipation of 250mW or greater

Acceptable Parameter Variations:

• On-resistance (Rds On) may be lower (improved performance)
• Gate threshold voltage may be lower (improved switching characteristics)
• Gate charge may be higher (acceptable for most applications)
• Input capacitance may be higher (acceptable for most applications)
• Operating temperature range may be wider (improved reliability margin)

The substitute part DMP2004DWK-7 meets all mandatory matching criteria and demonstrates improved electrical characteristics in on-resistance and gate threshold voltage while maintaining package and functional compatibility.

Engineering Selection Recommendations

DMP2004DWK-7 as Primary Substitute:

The DMP2004DWK-7 from Diodes Incorporated is the qualified substitute for the obsolete BSD223P. This substitution is supported by the following factors:

Functional Compatibility: The DMP2004DWK-7 maintains identical voltage and package specifications while providing superior electrical performance. The reduced on-resistance (0.9 Ohm versus 1.2 Ohm) and lower gate threshold voltage (1.0V versus 1.2V) result in improved switching efficiency and reduced power dissipation in typical applications.

Product Status and Availability: The DMP2004DWK-7 is classified as an active product with confirmed inventory availability of 35,200 units. This ensures long-term supply continuity and support for production requirements.

Regulatory and Compliance Status: The DMP2004DWK-7 carries RoHS3 compliance certification, exceeding the regulatory requirements of the obsolete BSD223P. Both devices maintain REACH Unaffected status and identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment.

Thermal Performance: The DMP2004DWK-7 supports an extended operating temperature range (-65°C to 150°C) compared to the BSD223P (-55°C to 150°C), providing additional thermal margin for demanding applications.

Package Compatibility: Both devices utilize the SOT-363 package with identical pin configurations and footprints, enabling direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the DMP2004DWK-7 be used as a direct replacement for the BSD223P in existing designs?

A: Yes. The DMP2004DWK-7 is functionally compatible with the BSD223P across all critical parameters. Both devices feature identical voltage ratings, package types, and logic-level gate operation. The improved electrical characteristics of the DMP2004DWK-7 (lower on-resistance and gate threshold voltage) provide enhanced performance without requiring circuit modifications.

Q: What are the key differences between the BSD223P and DMP2004DWK-7?

A: The primary differences are: (1) Product status—the BSD223P is obsolete while the DMP2004DWK-7 is active; (2) On-resistance—the DMP2004DWK-7 offers 0.9 Ohm versus 1.2 Ohm, reducing conduction losses; (3) Gate threshold voltage—the DMP2004DWK-7 specifies 1.0V versus 1.2V, improving switching speed; (4) Operating temperature range—the DMP2004DWK-7 extends to -65°C versus -55°C; (5) RoHS compliance—the DMP2004DWK-7 is RoHS3 compliant.

Q: Are there any package compatibility concerns when substituting the DMP2004DWK-7 for the BSD223P?

A: No. Both devices are packaged in the SOT-363 (6-pin) configuration with identical pin assignments and footprints. The BSD223P uses a 6-VSSOP variant while the DMP2004DWK-7 uses a 6-TSSOP variant, but both are mechanically and electrically compatible with standard SOT-363 land patterns. No PCB layout modifications are required.

Q: Will the improved on-resistance of the DMP2004DWK-7 affect circuit operation?

A: The lower on-resistance of the DMP2004DWK-7 (0.9 Ohm versus 1.2 Ohm) results in reduced conduction losses and lower junction temperatures during operation. This represents an improvement over the original BSD223P specification and does not introduce any compatibility issues. Circuits designed for the BSD223P will operate with equal or superior performance using the DMP2004DWK-7.

Q: What is the significance of the higher input capacitance in the DMP2004DWK-7?

A: The DMP2004DWK-7 specifies an input capacitance of 175pF at 16V compared to 56pF at 15V for the BSD223P. This higher capacitance value is acceptable for most logic-level switching applications and does not prevent substitution. Applications with stringent high-frequency switching requirements should verify gate drive circuit performance through simulation or testing.

Q: Are both devices suitable for new design applications?

A: The DMP2004DWK-7 is the appropriate choice for new designs. The BSD223P is classified as obsolete and should not be specified for new applications. The DMP2004DWK-7 provides superior electrical characteristics, active product status, confirmed long-term availability, and RoHS3 compliance, making it the preferred selection for all new development.

Q: What compliance certifications apply to both devices?

A: Both the BSD223P and DMP2004DWK-7 maintain REACH Unaffected status and identical ECCN (EAR99) and HTSUS (8541.21.0095) classifications. The DMP2004DWK-7 additionally carries RoHS3 compliance certification. Both devices feature MSL 1 (Unlimited) moisture sensitivity ratings, indicating no special handling requirements.
