Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GS1574-CNE3 is determined by strict alignment of the following critical parameters:

• Functional equivalence: Equalizer function for professional video applications
• Standards compliance: SMPTE standard adherence
• Electrical specifications: Supply voltage range 3.135V ~ 3.465V
• Control interface: Serial control capability
• Package compatibility: 16-QFN (4x4) surface mount with exposed pad
• Mounting type: Surface mount configuration

The GS2994-INE3 meets all substitution criteria as a manufacturer-recommended equivalent part from Semtech Corporation, maintaining identical functional, electrical, and mechanical specifications while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GS2994-INE3 is the manufacturer-recommended substitute for the obsolete GS1574-CNE3. Both components share identical functional, electrical, and mechanical specifications, ensuring direct compatibility in professional video applications requiring SMPTE-compliant serial-controlled equalization.

The GS2994-INE3 offers the following advantages for new designs and production continuity:

• Active product status ensures ongoing availability and manufacturer support
• ROHS3 compliance and REACH unaffected status meet current environmental and regulatory requirements
• Moisture Sensitivity Level 1 (Unlimited) provides superior handling flexibility compared to higher MSL ratings
• Identical 16-QFN (4x4) package and electrical specifications eliminate redesign requirements

Selection of the GS2994-INE3 is appropriate for applications where the GS1574-CNE3 was previously specified, provided that the identical electrical and mechanical parameters are confirmed for the target application.

Frequently Asked Questions (FAQ)

Q: Can the GS2994-INE3 directly replace the GS1574-CNE3 in existing designs?

A: Yes. Both components share identical supply voltage (3.135V ~ 3.465V), serial control interface, SMPTE standards compliance, and 16-QFN (4x4) package configuration. No circuit modifications are required for substitution.

Q: What is the primary reason for substituting the GS1574-CNE3?

A: The GS1574-CNE3 has reached obsolete product status. The GS2994-INE3 is the active equivalent part from the same manufacturer, ensuring continued supply chain availability and manufacturer support.

Q: Are there any compliance differences between these parts?

A: The GS2994-INE3 provides ROHS3 compliance and REACH unaffected status, which are not specified for the obsolete GS1574-CNE3. These certifications meet current environmental and regulatory requirements for professional video equipment.

Q: What does Moisture Sensitivity Level 1 (Unlimited) mean?

A: MSL 1 indicates the component can be stored indefinitely without moisture absorption concerns, providing maximum handling flexibility during manufacturing and assembly processes.

Q: Are the package dimensions identical?

A: Yes. Both components use the 16-VQFN Exposed Pad package in 4x4 millimeter configuration, ensuring identical PCB footprint and assembly compatibility.

Q: Is the GS2994-INE3 available in the same packaging format?

A: The GS2994-INE3 is supplied in Tray packaging, while the original GS1574-CNE3 packaging format is not specified. Confirm packaging requirements with your procurement department for production planning.
