GS2974BCNE3 Equivalent & Substitute Parts

Part Overview

The GS2974BCNE3 is a video cable equalizer IC manufactured by Semtech Corporation, designed for professional video applications utilizing DVB-ASI and SMPTE standards. This component operates as a serial-controlled equalizer in a 16-QFN (4x4) surface mount package with exposed pad. The part is currently classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs requiring similar video equalization capabilities.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the GS2974BCNE3 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Voltage supply range: 3.135V ~ 3.465V (exact match required)
• Package type: 16-QFN or 16-WQFN with exposed pad (4x4 footprint)
• Mounting type: Surface mount
• Control interface: Serial
• Application domain: Professional video or displays
• Standards support: SMPTE and/or DVB-ASI compatibility

Qualified Substitutes:

1. GS2994-INE3 (Semtech Corporation) – Manufacturer recommended substitute. Active product status. Maintains identical supply voltage range and package footprint. Improved moisture sensitivity (MSL 1 vs. MSL 3). ROHS3 and REACH compliant.

2. LMH0074SQ/NOPB (Texas Instruments) – Active product. Identical supply voltage and 16-WQFN package with exposed pad. Serial interface. Displays application focus with SMPTE standard support. ROHS3 and REACH compliant.

3. LMH0074SQE/NOPB (National Semiconductor) – Active product. Matches supply voltage and package specifications. Serial interface. Displays application with SMPTE 259M / 344M adaptive capability. Identical ECCN and HTSUS classifications.

Parameter Comparison

Engineering Selection Recommendations

GS2994-INE3 is the primary substitute option. As a Semtech Corporation product with active status, it maintains design continuity with the original GS2974BCNE3. The identical supply voltage range and package footprint ensure direct compatibility. Superior moisture sensitivity rating (MSL 1 vs. MSL 3) and confirmed ROHS3 / REACH compliance provide enhanced reliability and regulatory alignment for new production.

LMH0074SQ/NOPB and LMH0074SQE/NOPB serve as secondary alternatives when GS2994-INE3 availability is constrained. Both maintain the required supply voltage and serial interface specifications. The transition from VQFN to WQFN package variant requires PCB layout verification to confirm footprint compatibility, as these packages have identical pin counts and pitch but differ in body dimensions. Both alternatives carry active product status and ROHS3 compliance.

Selection between LMH0074SQ/NOPB (Texas Instruments) and LMH0074SQE/NOPB (National Semiconductor) depends on supply chain availability and existing vendor relationships, as electrical and mechanical specifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Can GS2994-INE3 be used as a direct replacement for GS2974BCNE3?

A: Yes. Both parts share identical supply voltage specifications (3.135V ~ 3.465V), package type (16-QFN with exposed pad, 4x4 footprint), mounting method (surface mount), and serial control interface. GS2994-INE3 is the manufacturer-recommended substitute with active product status.

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

A: Both are 16-pin QFN packages with 4x4mm footprint and identical pin pitch. VQFN and WQFN designations indicate different body dimensions and thermal characteristics. PCB layout compatibility must be verified before substituting between these package variants, as land pattern dimensions differ.

Q: Are the Texas Instruments and National Semiconductor LMH0074 variants interchangeable?

A: LMH0074SQ/NOPB and LMH0074SQE/NOPB share identical electrical specifications, supply voltage range, package type, and serial interface. Both are qualified substitutes. Selection is based on supply availability and procurement preferences.

Q: What does MSL 3 (168 Hours) mean for the original GS2974BCNE3?

A: Moisture Sensitivity Level 3 indicates the component requires baking at 125°C for up to 168 hours before reflow soldering if exposed to moisture. Substitute parts with MSL 1 (unlimited shelf life) eliminate this handling requirement, reducing production complexity.

Q: Are all substitute parts ROHS3 compliant?

A: GS2994-INE3 and LMH0074SQ/NOPB carry confirmed ROHS3 compliance. LMH0074SQE/NOPB compliance status is not specified in available documentation. Verify with the supplier for regulatory requirements.

Q: Do all parts share the same ECCN and HTSUS classifications?

A: Yes. All four parts (GS2974BCNE3, GS2994-INE3, LMH0074SQ/NOPB, and LMH0074SQE/NOPB) carry identical ECCN 5A991B1 and HTSUS 8542.39.0001 classifications for export and tariff purposes.
