Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GS1574ACNE3 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Electrical Compatibility:

• Voltage supply range: 3.135V ~ 3.465V (must match exactly)
• Function: Video equalizer IC
• Standards compliance: SMPTE

Mechanical Compatibility:

• Package type: 16-VQFN Exposed Pad
• Supplier device package: 16-QFN (4x4)
• Mounting type: Surface Mount

Substitution Logic: Parts meeting all electrical and mechanical parameters listed above are classified as direct substitutes. The GS2994-INTE3Z and GS1674-INE3 both satisfy these core compatibility requirements, enabling them to function as equivalent components in applications originally designed for the GS1574ACNE3.

Parameter Comparison

Engineering Selection Recommendations

GS2994-INTE3Z is the primary recommended substitute. This part maintains full electrical and mechanical compatibility with the GS1574ACNE3 while offering superior product status (Active) and improved moisture sensitivity characteristics (MSL 1 vs. MSL 3). The GS2994-INTE3Z is suitable for both ongoing production and new design implementations.

GS1674-INE3 is a secondary substitute option. While electrically and mechanically compatible, this part carries a "Not For New Designs" status designation, limiting its application to legacy system maintenance and existing production lines only. The GS1674-INE3 supports both DVB-ASI and SMPTE standards, providing broader standard compliance than the primary part.

Selection between these substitutes should be based on design phase requirements and long-term supply chain strategy. Active product status and improved handling characteristics favor the GS2994-INTE3Z for new implementations.

Frequently Asked Questions (FAQ)

Q: Can GS2994-INTE3Z be used as a direct replacement for GS1574ACNE3 in existing designs?

A: Yes. Both parts share identical electrical specifications (3.135V ~ 3.465V supply), package configuration (16-VQFN Exposed Pad, 16-QFN 4x4), mounting type (Surface Mount), and SMPTE standard compliance. Pin-to-pin compatibility and functional equivalence are established through these matching parameters.

Q: What is the difference between GS2994-INTE3Z and GS1674-INE3?

A: Both are electrically and mechanically compatible with GS1574ACNE3. Key differences include: GS2994-INTE3Z has Active product status and MSL 1 rating (unlimited moisture exposure), while GS1674-INE3 has "Not For New Designs" status and MSL 3 rating (168 hours). GS1674-INE3 additionally supports DVB-ASI standard compliance.

Q: Why is GS1574ACNE3 in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer has discontinued production and is accepting final orders. This necessitates identifying and qualifying substitute parts to maintain supply continuity for ongoing applications.

Q: Are there any compliance differences between the substitute parts?

A: GS2994-INTE3Z and GS1574ACNE3 are both ROHS3 Compliant. GS1674-INE3 is RoHS Compliant. All three parts are REACH Unaffected and share identical HTSUS classification (8542.39.0001).

Q: What is the significance of MSL rating differences?

A: Moisture Sensitivity Level (MSL) indicates maximum exposure time to moisture before component degradation. GS2994-INTE3Z (MSL 1, Unlimited) requires less stringent moisture control during storage and handling compared to GS1574ACNE3 and GS1674-INE3 (both MSL 3, 168 Hours).

Q: Can GS1674-INE3 be used in new product designs?

A: No. The "Not For New Designs" designation restricts GS1674-INE3 to legacy system support and existing production lines only. GS2994-INTE3Z is the appropriate choice for new design implementations.
