• Power Dissipation: Must equal or exceed 250mW
• Operating Temperature Range: Must encompass -55°C to 150°C
• Channel Type: Must be P-Channel MOSFET

Mechanical Compatibility Requirements:

• Package: SOT-323 (SC-70) surface mount only
• Mounting Type: Surface mount configuration

Compliance Requirements:

• RoHS3 compliance mandatory
• MSL rating of 1 (Unlimited) required

The BSS223PWH6327XTSA1 meets all substitution criteria within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The BSS223PWH6327XTSA1 from Infineon Technologies is a qualified substitute for the DMP2004WK-7 based on the following engineering criteria:

Electrical Equivalence: Both devices maintain identical Vdss (20V), power dissipation (250mW), and operating temperature range (-55°C to 150°C). The continuous drain current of the substitute (390mA) remains within acceptable tolerance of the primary part specification (400mA), representing a 2.5% reduction in current capacity.

Mechanical Compatibility: Both parts utilize the SOT-323 (SC-70) surface mount package with identical pinout and footprint requirements. No PCB layout modifications are required for substitution.

Compliance Status: Both devices carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.

Product Status: Both parts maintain active production status with established supply chains. The substitute part carries manufacturer designation as part of the OptiMOS™ series from Infineon.

Frequently Asked Questions (FAQ)

Q: Can the BSS223PWH6327XTSA1 be used as a direct replacement for the DMP2004WK-7 in existing designs?

A: Yes, the BSS223PWH6327XTSA1 is a direct substitute for surface mount applications. Both devices share identical SOT-323 package geometry, pinout, and electrical ratings within specified tolerances. No PCB modifications are required.

Q: What is the difference in drain current between these two parts?

A: The DMP2004WK-7 is rated for 400mA continuous drain current, while the BSS223PWH6327XTSA1 is rated for 390mA. This represents a 2.5% reduction in current capacity. Applications requiring the full 400mA specification should evaluate circuit margin before substitution.

Q: Are there differences in on-resistance between these devices?

A: Yes. The DMP2004WK-7 specifies 900mOhm maximum on-resistance at 430mA and 4.5V gate-source voltage. The BSS223PWH6327XTSA1 specifies 1.2Ohm maximum on-resistance at 390mA and 4.5V gate-source voltage. The substitute exhibits higher on-resistance, which may result in increased power dissipation in high-current applications.

Q: Do both parts have the same gate voltage rating?

A: No. The DMP2004WK-7 is rated for ±8V maximum gate-source voltage, while the BSS223PWH6327XTSA1 is rated for ±12V. The substitute part provides higher gate voltage tolerance. Designs operating within ±8V are compatible with both devices.

Q: Are there differences in input capacitance?

A: Yes. The DMP2004WK-7 specifies 175pF maximum input capacitance at 16V, while the BSS223PWH6327XTSA1 specifies 56pF maximum input capacitance at 15V. The substitute part has significantly lower input capacitance, which may affect switching speed and gate drive requirements in high-frequency applications.

Q: What compliance certifications apply to both parts?

A: Both the DMP2004WK-7 and BSS223PWH6327XTSA1 carry ROHS3 compliance certification and are classified as MSL 1 (Unlimited) for moisture sensitivity. Both parts are REACH Unaffected and carry EAR99 ECCN classification.

Q: Are there any temperature operating range differences?

A: No. Both devices operate across the identical temperature range of -55°C to 150°C junction temperature, ensuring equivalent thermal performance across all operating conditions.
