GS9077-CNE3 Equivalent & Substitute Parts

Part Overview

The GS9077-CNE3 is a Cable Driver IC manufactured by Semtech Corporation in a 16-QFN (4x4) surface mount package. This component is classified as an interface device within the HD-LINX® III series and is designated as obsolete. Due to its obsolete status, identifying functionally equivalent substitute parts is essential for ongoing system support, design updates, and procurement continuity. The substitutes listed maintain compatibility through matching package specifications, mounting type, and core driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GS9077-CNE3 is determined by the following critical parameters:

• Package Compatibility: Both substitute parts maintain the 16-VQFN Exposed Pad package with 16-QFN (4x4) supplier device package specification, ensuring PCB footprint and assembly process compatibility.
• Mounting Type: Surface mount configuration is preserved across all substitute options.
• Manufacturer Consistency: All parts are manufactured by Semtech Corporation, maintaining design ecosystem compatibility.
• Moisture Sensitivity Level: MSL 3 (168 Hours) is maintained across all parts, ensuring equivalent handling and storage requirements.
• HTSUS Classification: All parts share the same tariff code (8542.39.0001), confirming functional category alignment.

The two substitute parts (GS2988-INE3 and GS1678-INE3) are classified as driver ICs with video cable driver functionality, representing the active and legacy alternatives to the obsolete GS9077-CNE3.

Parameter Comparison

Engineering Selection Recommendations

GS2988-INE3 is the primary substitute option. This part carries Active product status, indicating ongoing manufacturer support and availability. It maintains ROHS3 compliance, representing the most current regulatory standard. With 22,571 units in stock, procurement reliability is established. This part is suitable for both legacy system maintenance and new design implementations.

GS1678-INE3 is a secondary substitute option designated as Not For New Designs. While it maintains full package and mounting compatibility with the GS9077-CNE3, its restricted design status indicates limited future support. This part is appropriate only for sustaining existing systems where the GS9077-CNE3 is currently deployed. With 1,953 units available, inventory is more limited than the primary substitute.

Both substitutes preserve the 16-QFN (4x4) package footprint and MSL 3 moisture sensitivity specification, enabling direct replacement in existing PCB layouts without redesign.

Frequently Asked Questions (FAQ)

Q: Can GS2988-INE3 and GS1678-INE3 be used interchangeably with GS9077-CNE3?

A: Both parts share identical package specifications (16-VQFN Exposed Pad, 16-QFN 4x4), mounting type (Surface Mount), and moisture sensitivity level (MSL 3). PCB footprint compatibility is confirmed. However, functional equivalence depends on application-specific requirements not detailed in the component specifications provided. Electrical interface verification is required before implementation.

Q: Why is GS9077-CNE3 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. GS2988-INE3 (Active status) and GS1678-INE3 (Not For New Designs status) represent the current product line alternatives from Semtech Corporation.

Q: What is the difference between ROHS3 and RoHS compliance?

A: ROHS3 represents the most current version of the Restriction of Hazardous Substances directive. GS2988-INE3 meets ROHS3 standards, while GS9077-CNE3 and GS1678-INE3 meet RoHS Compliant standards. Both certifications restrict hazardous materials; ROHS3 reflects the latest regulatory requirements.

Q: Are there inventory considerations for substitute selection?

A: GS2988-INE3 has 22,571 units in stock, providing strong procurement availability. GS1678-INE3 has 1,953 units available. For long-term production requirements, GS2988-INE3 offers superior supply chain reliability.

Q: Does MSL 3 (168 Hours) affect handling procedures?

A: MSL 3 specifies that the component can be exposed to moisture for up to 168 hours at 85°C and 85% relative humidity before soldering. All three parts share this specification, so existing handling and storage procedures remain valid across substitutes.
