FDG6323L Equivalent & Substitute Parts

Part Overview

The FDG6323L is a power switch/driver IC manufactured by onsemi, designed for high-side P-channel switching applications. This component operates across a 2.5V to 8V load voltage range with a maximum output current of 600mA and typical on-resistance of 410mOhm. The device is packaged in a 6-TSSOP SC-88 (SOT-363) surface mount configuration.

The FDG6323L is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure availability for new production runs or system updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FDG6323L is determined by the following critical parameters:

• Package Compatibility: Both the main part and substitute must use the 6-TSSOP SC-88 SOT-363 surface mount package to ensure PCB footprint compatibility.
• Voltage Rating: The substitute must support the load voltage range of 2.5V to 8V and supply voltage range of 1.5V to 8V.
• Current Capability: The substitute must support a minimum continuous drain current of 600mA at the specified operating conditions.
• On-Resistance: The substitute's Rds On must not significantly exceed the typical 410mOhm specification to maintain circuit performance.
• Operating Temperature Range: The substitute must support the full -55°C to 150°C (TJ) operating range.
• Mounting Type: Surface mount technology is required for PCB assembly compatibility.

The NTJD1155LT1G meets these substitution criteria as an active, in-stock alternative from onsemi.

Engineering Selection Recommendations

The NTJD1155LT1G is the qualified substitute for the obsolete FDG6323L. Selection is based on the following factors:

• Active Product Status: The NTJD1155LT1G is an active product with confirmed inventory availability (41,400 pcs in stock), ensuring long-term supply continuity compared to the obsolete FDG6323L.
• Regulatory Compliance: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance requirements.
• Package Equivalence: Identical 6-TSSOP SC-88 SOT-363 packaging ensures direct PCB footprint compatibility without layout modifications.
• Enhanced Performance: The NTJD1155LT1G provides superior electrical characteristics, including higher continuous drain current (1.3A vs. 600mA) and lower on-resistance (175mOhm max vs. 410mOhm typical), delivering improved thermal performance and reduced power dissipation.
• Temperature Range Alignment: Full operating temperature range compatibility (-55°C to 150°C TJ) ensures performance across all specified environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the NTJD1155LT1G be used as a direct replacement for the FDG6323L without PCB modifications?

A: Yes. Both components use the identical 6-TSSOP SC-88 SOT-363 package, enabling direct pin-for-pin substitution without PCB layout changes.

Q: What are the key electrical differences between these parts?

A: The NTJD1155LT1G provides higher current capability (1.3A continuous vs. 600mA) and lower on-resistance (175mOhm max vs. 410mOhm typical). These improvements result in reduced power dissipation and better thermal performance in the same package.

Q: Are there any compliance or certification concerns when switching to the NTJD1155LT1G?

A: No. Both components maintain identical REACH and ECCN classifications, ensuring regulatory compliance is preserved during the substitution.

Q: Why is the FDG6323L classified as obsolete?

A: The FDG6323L has been discontinued by onsemi. The NTJD1155LT1G represents the active alternative that meets or exceeds the original specifications.

Q: Does the NTJD1155LT1G support the same voltage operating ranges as the FDG6323L?

A: Yes. The NTJD1155LT1G supports the required load voltage range (2.5V to 8V) and supply voltage range (1.5V to 8V) specified for the FDG6323L.

Q: What is the moisture sensitivity level for the NTJD1155LT1G?

A: The NTJD1155LT1G has an MSL rating of 1 (Unlimited), matching the FDG6323L and indicating no moisture sensitivity constraints for storage or handling.
