FDG6332C Equivalent & Substitute Parts

Part Overview

The FDG6332C is an active MOSFET array featuring integrated N-channel and P-channel transistors in a compact surface mount package. Manufactured by onsemi under the PowerTrench® series, this component operates at 20V drain-to-source voltage with continuous drain current ratings of 700mA and 600mA. The device is housed in a 6-TSSOP (SC-88, SOT-363) package and is designed for logic-level gate applications requiring low on-resistance performance.

Substitute parts become necessary when the primary component experiences extended lead times, inventory constraints, or when design flexibility permits selection from qualified alternatives that meet identical electrical and mechanical specifications. The FDG6332C maintains active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FDG6332C is determined by strict alignment across the following critical parameters:

Package Compatibility: All substitute parts must use the 6-TSSOP (SC-88, SOT-363) surface mount package to ensure mechanical and electrical compatibility with existing PCB layouts and solder reflow processes.

Voltage Rating: Substitute parts must maintain a minimum drain-to-source voltage (Vdss) rating of 20V to support the same circuit operating conditions.

Configuration: Substitute parts must feature integrated N-channel and P-channel transistor arrays to match the dual-channel functionality of the primary device.

Gate Feature: Substitute parts must incorporate logic-level gate operation to maintain compatibility with standard digital control signals.

Operating Temperature Range: Substitute parts must support the full -55°C to 150°C junction temperature range to ensure reliability across identical thermal environments.

Compliance Standards: All substitute parts must maintain RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1) to satisfy regulatory and manufacturing requirements.

Current and Power Ratings: While substitute parts may exhibit variations in continuous drain current and on-resistance specifications, these variations must remain within acceptable design margins for the target application. Drain current ratings of 630mA to 725mA and power dissipation ratings of 270mW to 300mW represent acceptable performance envelopes.

Parameter Comparison

Engineering Selection Recommendations

NTJD4105CT1G (onsemi): This substitute maintains identical manufacturer origin and shares the PowerTrench® technology platform with the FDG6332C. The NTJD4105CT1G provides equivalent 20V drain-to-source voltage rating and logic-level gate operation. Continuous drain current specifications of 630mA and 775mA remain within acceptable operating margins relative to the primary device. The component is active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Gate charge specification of 3nC represents a measurable increase compared to the primary device, which may impact switching speed characteristics in high-frequency applications. This substitute is suitable for direct replacement in standard switching and logic-level applications.

PMGD290UCEAX (Nexperia USA Inc.): This substitute provides equivalent 20V drain-to-source voltage and logic-level gate functionality with identical package configuration. The PMGD290UCEAX is qualified to AEC-Q100 automotive standards, providing additional qualification assurance for applications requiring automotive-grade components. Continuous drain current of 725mA exceeds the primary device specification, while on-resistance of 380mOhm remains comparable. Gate charge specification of 0.68nC is significantly lower than the primary device, enabling faster switching transitions in applications sensitive to gate charge performance. This substitute is active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. The automotive qualification provides enhanced reliability documentation for mission-critical applications.

Both substitute parts satisfy all mandatory substitution criteria: identical package type, equivalent voltage ratings, matching configuration, logic-level gate operation, full temperature range support, and regulatory compliance. Selection between substitutes depends on application-specific requirements regarding gate charge performance and automotive qualification status.

Frequently Asked Questions (FAQ)

Q: Can the NTJD4105CT1G be used as a direct replacement for the FDG6332C in existing designs?

A: Yes. The NTJD4105CT1G shares identical package configuration (6-TSSOP, SC-88, SOT-363), drain-to-source voltage rating (20V), and logic-level gate operation. Both components feature N-channel and P-channel configuration with equivalent operating temperature ranges (-55°C to 150°C). The substitute maintains RoHS3 compliance and unlimited moisture sensitivity rating. Differences in gate charge (3nC versus 1.5nC) and on-resistance (375mOhm versus 300mOhm) must be evaluated within specific circuit requirements.

Q: What are the key differences between the PMGD290UCEAX and the FDG6332C?

A: The PMGD290UCEAX provides equivalent 20V voltage rating and package configuration but differs in gate charge specification (0.68nC versus 1.5nC) and on-resistance (380mOhm versus 300mOhm). The PMGD290UCEAX includes AEC-Q100 automotive qualification, which the FDG6332C does not specify. Both components support identical operating temperature ranges and maintain full RoHS3 compliance.

Q: Are all three parts (FDG6332C, NTJD4105CT1G, PMGD290UCEAX) mechanically interchangeable?

A: Yes. All three components use the 6-TSSOP (SC-88, SOT-363) surface mount package with identical pin configurations. PCB layouts designed for the FDG6332C accommodate both substitute parts without modification. Solder reflow profiles and assembly processes remain unchanged.

Q: Does gate charge variation affect circuit performance?

A: Gate charge influences switching speed and driver current requirements. The FDG6332C specifies 1.5nC gate charge, the NTJD4105CT1G specifies 3nC, and the PMGD290UCEAX specifies 0.68nC. Applications operating at high switching frequencies or with current-limited gate drivers must account for these variations. Lower gate charge (PMGD290UCEAX) enables faster switching transitions, while higher gate charge (NTJD4105CT1G) requires proportionally higher driver current.

Q: Which substitute is recommended for automotive applications?

A: The PMGD290UCEAX is qualified to AEC-Q100 automotive standards, providing documented reliability assurance for automotive-grade applications. The FDG6332C and NTJD4105CT1G do not specify automotive qualification. Selection of the PMGD290UCEAX is appropriate when automotive qualification documentation is required by design specifications or supply chain requirements.

Q: Can these parts be used interchangeably in high-frequency switching applications?

A: Gate charge and input capacitance specifications must be evaluated for high-frequency operation. The PMGD290UCEAX features the lowest gate charge (0.68nC) and moderate input capacitance (83pF), supporting faster switching transitions. The NTJD4105CT1G exhibits higher gate charge (3nC) and lower input capacitance (46pF), which may limit switching frequency performance. The FDG6332C provides intermediate characteristics (1.5nC gate charge, 113pF input capacitance). Application-specific frequency requirements determine optimal part selection.

Q: Are all substitute parts available in the same packaging options?

A: All three components are available in Cut Tape (CT) and Digi-Reel® packaging formats, supporting both manual and automated assembly processes. Packaging format selection does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to all three parts?

A: All three components maintain RoHS3 compliance, unlimited moisture sensitivity rating (MSL 1), REACH unaffected status, and EAR99 export classification. The PMGD290UCEAX additionally carries AEC-Q100 automotive qualification. All parts are classified under HTSUS code 8541.21.0095.
