Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GS1574ACTE3 is determined by the following critical parameters:

• Supply voltage range: 3.135V ~ 3.465V
• Package type: 16-pin QFN with 4x4mm footprint and exposed pad
• Control interface: Serial
• Mounting type: Surface Mount
• Pin count and physical dimensions compatibility

The LMH0044SQ/NOPB from Texas Instruments meets these core electrical and mechanical requirements. Both components operate within the same supply voltage specification, utilize compatible 16-pin QFN packages with exposed pads, and support serial control interfaces. The functional application differs (data transport interface versus video equalizer), but the electrical and physical compatibility parameters align, enabling substitution in designs where the specific signal processing characteristics of the LMH0044SQ/NOPB are suitable for the intended application.

Parameter Comparison

Engineering Selection Recommendations

The GS1574ACTE3 is in Last Time Buy status, making substitute identification critical for ongoing production. The LMH0044SQ/NOPB is an Active product from Texas Instruments with established supply availability (5088 pcs in stock versus 990 pcs for the GS1574ACTE3).

Both components share identical supply voltage specifications (3.135V ~ 3.465V) and compatible 16-pin QFN package geometries with exposed pads. The LMH0044SQ/NOPB carries ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. The moisture sensitivity level of 1 (Unlimited) indicates robust handling characteristics.

Selection between these components should be based on functional requirements specific to the application. While the GS1574ACTE3 is optimized for video equalization, the LMH0044SQ/NOPB is designed for data transport interface applications. Electrical and mechanical compatibility is established; functional suitability must be validated against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the LMH0044SQ/NOPB directly replace the GS1574ACTE3 in existing designs?

A: Electrical and mechanical compatibility is confirmed through matching supply voltage ranges, package types, and serial control interfaces. However, functional compatibility depends on whether the data transport interface characteristics of the LMH0044SQ/NOPB align with the signal processing requirements of your application. Circuit-level validation is necessary.

Q: Are the QFN package variants (VQFN vs WQFN) interchangeable?

A: Both the 16-VQFN and 16-WQFN packages maintain the same 4x4mm footprint and exposed pad configuration. Pin assignments and electrical characteristics are compatible for substitution purposes. Verify PCB layout compatibility with your design specifications.

Q: What is the significance of the Last Time Buy status for the GS1574ACTE3?

A: Last Time Buy indicates that Semtech Corporation will no longer manufacture this component after a specified cutoff date. Identifying and qualifying substitute parts is essential for designs requiring continued production beyond this date.

Q: How do the supply voltage specifications compare?

A: Both components operate within the identical 3.135V ~ 3.465V supply voltage range, eliminating voltage regulation modifications in substitution scenarios.

Q: What compliance certifications should be considered?

A: The LMH0044SQ/NOPB carries ROHS3 compliance and REACH Unaffected status. Verify that your application requirements align with these regulatory standards.
