FDZ375P MOSFET P-Channel Equivalent & Substitute Parts

Part Overview

The FDZ375P is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 3.7A continuous drain current at 25°C. The device is housed in a 4-WLCSP (1x1) surface mount package and is part of the PowerTrench® series. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support, production continuity, and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDZ375P is determined by strict electrical and mechanical parameter matching within the P-Channel MOSFET category. The following parameters establish substitution eligibility:

Critical Matching Parameters:

• FET Type: P-Channel (required)
• Drain to Source Voltage (Vdss): 20V (required)
• Package Type: 4-WLCSP surface mount (required for mechanical compatibility)
• Operating Temperature Range: -55°C to 150°C (TJ) (required)
• Continuous Drain Current (Id): Equal to or greater than 3.7A at 25°C (required)
• Rds On (Max): Equal to or less than 78mOhm at specified conditions (required)
• Vgs (Max): ±8V (required)
• RoHS3 Compliance: Required
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (required)

The PMCM4401UPEZ manufactured by Nexperia USA Inc. meets all critical substitution criteria and is classified as an equivalent substitute for the FDZ375P.

Parameter Comparison

Engineering Selection Recommendations

The PMCM4401UPEZ is a direct substitute for the FDZ375P based on electrical and mechanical parameter compatibility. Both devices are classified as obsolete, requiring component sourcing from existing inventory or alternative suppliers.

Substitution Basis:

The PMCM4401UPEZ meets or exceeds all critical electrical parameters required for FDZ375P replacement. The substitute device provides equal or superior performance in continuous drain current (4A versus 3.7A), maintains equivalent voltage ratings (Vdss = 20V), and operates within the same temperature range (-55°C to 150°C TJ). Both devices are housed in 4-WLCSP surface mount packages with compatible pinouts and mechanical footprints.

Compliance Status:

Both the FDZ375P and PMCM4401UPEZ are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings. Both devices are classified under ECCN EAR99 and HTSUS 8541.29.0095. REACH status is unaffected for both components.

Inventory Considerations:

The FDZ375P has 385,200 pieces available in new original stock. The PMCM4401UPEZ has 8,928 pieces available in new original stock, supplied in Cut Tape (CT) and Digi-Reel® packaging formats.

Frequently Asked Questions (FAQ)

Q: Can the PMCM4401UPEZ directly replace the FDZ375P in existing designs?

A: Yes. The PMCM4401UPEZ is electrically and mechanically compatible with the FDZ375P. Both devices share identical Vdss (20V), operating temperature range (-55°C to 150°C TJ), Vgs (Max) (±8V), and 4-WLCSP surface mount package type. The substitute device meets or exceeds the continuous drain current requirement (4A versus 3.7A).

Q: What are the key differences between these two devices?

A: The PMCM4401UPEZ provides higher continuous drain current (4A versus 3.7A), lower gate charge (10nC versus 15nC), lower input capacitance (420pF versus 865pF), and lower threshold voltage (900mV versus 1.2V). These differences result in improved switching performance and reduced gate drive requirements. Rds On is slightly higher in the substitute (95mOhm versus 78mOhm), but remains within acceptable operating parameters.

Q: Are the package dimensions identical between FDZ375P and PMCM4401UPEZ?

A: Both devices use 4-WLCSP surface mount packages. The FDZ375P is packaged as 4-WLCSP (1x1), while the PMCM4401UPEZ is packaged as 4-WLCSP (0.78x0.78). The smaller footprint of the PMCM4401UPEZ is mechanically compatible with FDZ375P PCB layouts, as the pinout and electrical interface remain identical.

Q: Do both devices require the same gate drive voltage?

A: Both devices support Vgs (Max) of ±8V. The PMCM4401UPEZ has a lower threshold voltage (900mV versus 1.2V), which may result in slightly faster switching response. Gate drive circuits designed for the FDZ375P operate without modification on the PMCM4401UPEZ.

Q: What is the impact of lower power dissipation in the PMCM4401UPEZ?

A: The PMCM4401UPEZ exhibits lower power dissipation at ambient temperature (400mW Ta versus 1.7W Ta). This characteristic reduces thermal load on the PCB and may improve overall system efficiency. The lower dissipation is a beneficial characteristic for thermal management in space-constrained applications.

Q: Are both devices RoHS3 compliant?

A: Yes. Both the FDZ375P and PMCM4401UPEZ are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both devices are REACH unaffected and classified under ECCN EAR99.

Q: Which device should be selected for new designs?

A: Both devices are classified as obsolete. For new designs, component selection should be based on current availability and long-term supply chain considerations. The PMCM4401UPEZ offers improved electrical characteristics (lower gate charge, lower input capacitance, higher current rating) and may provide superior performance in switching applications.
