FDZ193P MOSFET P-Channel Equivalent & Substitute Parts

Part Overview

The FDZ193P is a P-Channel MOSFET manufactured by onsemi, rated for 20V drain-to-source voltage with 3A continuous drain current. This device is packaged in a 6-WLCSP (1x1.5mm) surface mount configuration and is classified as obsolete. Due to its obsolete product status, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDZ193P is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• FET Type: P-Channel topology must be maintained
• Drain to Source Voltage (Vdss): Minimum 20V rating required
• Continuous Drain Current (Id): Minimum 3A at 25°C required
• Gate Voltage (Vgs Max): Must accommodate circuit drive voltage requirements
• Operating Temperature Range: Must support -55°C to 150°C (TJ) or equivalent

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount required
• Package Type: WLCSP (Wafer Level Chip Scale Package) preferred for form factor compatibility

The substitute part PMCM4402UPEZ meets the electrical requirements with a higher continuous drain current rating (4.2A) and equivalent 20V Vdss rating. However, the package footprint differs (4-WLCSP 0.78x0.78mm versus 6-WLCSP 1x1.5mm), requiring PCB layout evaluation.

Parameter Comparison

Engineering Selection Recommendations

Compliance and Regulatory Status: Both the FDZ193P and PMCM4402UPEZ are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. Both devices carry EAR99 ECCN classification and are subject to the same HTSUS tariff code (8541.29.0095).

Product Status Consideration: Both parts are classified as obsolete. Selection between these devices should prioritize long-term availability and inventory status. The PMCM4402UPEZ currently maintains higher inventory levels (17,137 pcs) compared to the FDZ193P (9,010 pcs), providing greater supply security for future production requirements.

Electrical Performance: The PMCM4402UPEZ provides superior continuous drain current capability (4.2A versus 3A), making it suitable for applications requiring higher current handling. The lower gate charge (6.2nC versus 10nC) reduces driver circuit complexity. However, the reduced maximum gate voltage (±8V versus ±12V) and lower power dissipation rating (0.4W versus 1.9W) must be evaluated against specific circuit requirements.

Physical Form Factor: The PMCM4402UPEZ employs a smaller 4-WLCSP package (0.78x0.78mm) compared to the FDZ193P 6-WLCSP package (1x1.5mm). This reduction in footprint requires PCB layout redesign and may impact thermal management characteristics. Pin configuration differences necessitate schematic and layout verification before implementation.

Frequently Asked Questions (FAQ)

Q: Can the PMCM4402UPEZ directly replace the FDZ193P without PCB modifications?

A: No. While both devices are P-Channel MOSFETs with 20V Vdss ratings, the package types differ significantly. The FDZ193P uses a 6-WLCSP (1x1.5mm) package, while the PMCM4402UPEZ uses a 4-WLCSP (0.78x0.78mm) package. PCB footprint redesign is required. Pin-to-pin compatibility must be verified against the respective datasheets before implementation.

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

A: The PMCM4402UPEZ offers higher continuous drain current (4.2A versus 3A) and lower gate charge (6.2nC versus 10nC). However, it has a lower maximum gate voltage rating (±8V versus ±12V) and reduced power dissipation capability (0.4W versus 1.9W). Circuit design must accommodate these parameter differences.

Q: Are both devices suitable for the same operating temperature range?

A: Both devices support a maximum junction temperature of 150°C. The FDZ193P specifies an operating range of -55°C to 150°C (TJ). The PMCM4402UPEZ datasheet specifies 150°C maximum. Minimum operating temperature for the PMCM4402UPEZ should be verified against the manufacturer's datasheet before thermal design finalization.

Q: What is the significance of the different Rds On specifications?

A: The FDZ193P specifies Rds On (Max) of 90mOhm at 1A, 4.5V gate voltage. The PMCM4402UPEZ does not provide Rds On specifications in the available data. This parameter directly affects power dissipation and switching losses. Detailed datasheet review is required to compare on-resistance characteristics under equivalent test conditions.

Q: Why do both devices have obsolete product status?

A: Both the FDZ193P and PMCM4402UPEZ are classified as obsolete by their respective manufacturers. This status indicates that new production has ceased. Component selection should prioritize devices with active production status where possible. Current inventory availability should be confirmed with authorized distributors before design commitment.

Q: How does the package size reduction affect thermal performance?

A: The PMCM4402UPEZ 4-WLCSP package (0.78x0.78mm) is significantly smaller than the FDZ193P 6-WLCSP package (1x1.5mm). Smaller packages typically exhibit higher thermal resistance. The PMCM4402UPEZ lower power dissipation rating (0.4W versus 1.9W) reflects this thermal constraint. Thermal management and PCB copper area allocation must be re-evaluated for the smaller package.

Q: What compliance certifications apply to both devices?

A: Both devices are ROHS3 compliant, REACH unaffected, and classified under EAR99 ECCN. Both carry HTSUS code 8541.29.0095. Moisture sensitivity level (MSL) is 1 (Unlimited) for both devices, indicating no special moisture control requirements during storage or handling.
