GS2974BCNTE3 Equivalent & Substitute Parts

Part Overview

The GS2974BCNTE3 is a video cable equalizer IC manufactured by Semtech Corporation, designed for professional video applications supporting DVB-ASI and SMPTE standards. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing system maintenance. The part operates within a 3.135V to 3.465V supply voltage range and is housed in a 16-QFN (4x4) surface mount package with exposed pad.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the GS2974BCNTE3 is determined by the following critical parameters:

• Package Compatibility: 16-QFN (4x4) or 16-WQFN (4x4) surface mount packages with exposed pad
• Voltage Supply Range: 3.135V ~ 3.465V
• Interface Type: Serial control interface
• Mounting Type: Surface mount
• Application Domain: Professional video and data transport

The substitute parts listed below meet these core electrical and mechanical requirements. GS2994-INTE3 is the manufacturer-recommended direct replacement from Semtech Corporation. The Texas Instruments and National Semiconductor alternatives (LMH0044SQ/NOPB, LMH0074SQ/NOPB, LMH0074SQE/NOPB) provide functional equivalence through compatible packaging, voltage specifications, and serial interface architecture, though they serve broader interface applications including data transport and displays.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: GS2994-INTE3 is the manufacturer-recommended substitute from Semtech Corporation. This part maintains identical electrical specifications, package dimensions, and functional classification as the obsolete GS2974BCNTE3. The GS2994-INTE3 carries active product status and RoHS compliance certification, making it the preferred choice for new designs and direct replacement applications.

Alternative Selections: The Texas Instruments LMH0044SQ/NOPB and LMH0074SQ/NOPB, along with the National Semiconductor LMH0074SQE/NOPB, provide functional equivalence through matching voltage supply ranges, serial interface architecture, and compatible 16-QFN/16-WQFN packaging. These alternatives are suitable for applications where the broader interface classification (data transport and displays) aligns with system requirements. All three alternatives maintain active product status and superior moisture sensitivity ratings (MSL 1 vs. MSL 3).

Frequently Asked Questions (FAQ)

Q: Can GS2994-INTE3 be used as a direct replacement for GS2974BCNTE3?

A: Yes. GS2994-INTE3 is the manufacturer-recommended substitute with identical voltage supply specifications (3.135V ~ 3.465V), matching package configuration (16-QFN 4x4 with exposed pad), and equivalent serial control interface. Both parts are classified as linear equalizers for professional video applications.

Q: What is the difference between 16-VQFN and 16-WQFN packages?

A: Both designations refer to 16-pin quad flat no-lead packages in 4x4mm form factor with exposed thermal pads. The VQFN and WQFN variants are mechanically and electrically compatible for surface mount applications. Pin pitch and pad dimensions remain consistent across these package types.

Q: Are the Texas Instruments LMH parts suitable for DVB-ASI and SMPTE video applications?

A: The LMH0044SQ/NOPB and LMH0074SQ/NOPB are classified as interface components for data transport and displays respectively, rather than dedicated video equalizers. While they meet the electrical and mechanical substitution criteria (voltage range, package, serial interface), their functional classification differs from the GS2974BCNTE3. Application-specific validation is required to confirm compatibility with DVB-ASI and SMPTE standards.

Q: What does MSL 3 (168 Hours) mean for the GS2974BCNTE3?

A: Moisture Sensitivity Level 3 indicates the component requires controlled storage conditions with a maximum floor life of 168 hours after exposure to ambient humidity. The substitute parts with MSL 1 (Unlimited) offer superior moisture tolerance and reduced handling constraints during manufacturing and assembly.

Q: Is RoHS compliance required for my application?

A: RoHS compliance depends on your end-market and regulatory jurisdiction. GS2994-INTE3, LMH0044SQ/NOPB, and LMH0074SQ/NOPB all carry RoHS certification. If RoHS compliance is mandatory, these three options are suitable; the original GS2974BCNTE3 does not specify RoHS status.

Q: What inventory availability should I expect?

A: GS2974BCNTE3 (obsolete) has 1045 units in stock. GS2994-INTE3 (active) has 1706 units available. LMH0044SQ/NOPB has 5088 units, LMH0074SQ/NOPB has 2300 units, and LMH0074SQE/NOPB has 4671 units in stock. Availability of active parts ensures long-term supply continuity.
