Key Parameters

Substitute Part Grouping Explanation

Substitution of the GS1574-CTE3 is determined by the following critical parameters:

• Functional equivalence as a video cable equalizer
• SMPTE standards compliance for professional video applications
• Serial control interface compatibility
• Identical supply voltage range (3.135V ~ 3.465V)
• Identical package specification (16-VQFN Exposed Pad / 16-QFN 4x4)
• Surface mount mounting type
• Manufacturer continuity (Semtech Corporation)

The GS2994-INTE3Z meets all substitution criteria as the manufacturer-recommended equivalent, with the additional advantage of active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The GS2994-INTE3Z is the direct substitute for the obsolete GS1574-CTE3. Both components share identical electrical specifications, package geometry, and functional characteristics for SMPTE-compliant professional video applications.

The GS2994-INTE3Z provides additional advantages:

• Active product status ensures continued availability and manufacturing support
• ROHS3 compliance certification
• Moisture Sensitivity Level 1 rating indicates superior handling characteristics
• Higher inventory availability (3532 units in stock versus 921 units for the obsolete part)

For new designs and system replacements, the GS2994-INTE3Z is the appropriate selection. For legacy system maintenance requiring the GS1574-CTE3, the GS2994-INTE3Z provides full functional and mechanical compatibility.
