Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the NCT6793D are identified based on the following criteria:

Primary Substitution Parameters:

• Category: Interface
• Functional Application: Controller or specialized interface functionality
• Compliance: ROHS3 Compliant and REACH Unaffected status
• Mounting Type: Surface Mount
• Package Type: LQFP (Leadless Quad Flat Package)

The NCT6796D-E represents a direct manufacturer evolution within the Nuvoton product line, offering embedded controller functionality with enhanced specifications. The AD9985ABSTZ-110, while from a different manufacturer (Analog Devices Inc.), provides interface specialization in the video domain with compatible electrical and mechanical parameters.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original component.

Parameter Comparison

Engineering Selection Recommendations

NCT6796D-E Selection Criteria: The NCT6796D-E is the preferred substitute when direct functional replacement within the Nuvoton controller interface ecosystem is required. This part maintains active product status, ensuring long-term availability and supply chain stability. The 128-LQFP package provides expanded pin count compared to the original NCT6793D, offering enhanced functionality for embedded controller applications. ROHS3 compliance and REACH unaffected status align with regulatory requirements.

AD9985ABSTZ-110 Selection Criteria: The AD9985ABSTZ-110 serves as an alternative interface solution for applications requiring video interface specialization. This part is currently in Last Time Buy status, indicating limited remaining availability. Selection of this substitute should be evaluated based on specific application requirements for video interface functionality. The 80-LQFP package and specified voltage supply range (2.2V ~ 3.45V) must be verified for compatibility with system design parameters.

Compliance Assurance: Both substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with environmental and hazardous substance directives applicable to the original NCT6793D.

Frequently Asked Questions (FAQ)

Q: Can the NCT6796D-E directly replace the NCT6793D in existing designs? A: The NCT6796D-E is a Nuvoton manufacturer substitute offering controller interface functionality with active product status. Pin-to-pin compatibility and functional equivalence must be verified against specific application requirements and PCB layout constraints. The 128-LQFP package specification should be confirmed against the original design.

Q: What is the difference between the two substitute parts? A: The NCT6796D-E is a Nuvoton embedded controller interface in 128-LQFP package with active product status. The AD9985ABSTZ-110 is an Analog Devices video interface IC in 80-LQFP package with Last Time Buy status. Selection depends on application-specific interface requirements (controller versus video functionality).

Q: Are both substitute parts RoHS and REACH compliant? A: Yes. Both the NCT6796D-E and AD9985ABSTZ-110 are ROHS3 compliant and REACH unaffected, matching the compliance status of the original NCT6793D.

Q: What does "Last Time Buy" status mean for the AD9985ABSTZ-110? A: Last Time Buy indicates limited remaining inventory availability. This part is in the final phase of its product lifecycle. Procurement decisions should account for potential supply constraints.

Q: Are there package compatibility considerations? A: Yes. The NCT6796D-E uses 128-LQFP (14x14) packaging, while the AD9985ABSTZ-110 uses 80-LQFP (14x14) packaging. Both share the same footprint dimensions (14x14mm) but differ in pin count. PCB layout and schematic compatibility must be verified before substitution.

Q: What voltage supply ranges are specified for the substitute parts? A: The NCT6796D-E operates at 1.71V ~ 1.89V and 3.135V ~ 3.465V. The AD9985ABSTZ-110 operates at 2.2V ~ 3.45V. System power supply specifications must be verified for compatibility.
