Substitute Part Grouping Explanation

The GS2988-INE3 qualifies as a direct substitute for the GS2978-CNE3 based on the following critical parameters:

• Identical manufacturer (Semtech Corporation)
• Identical package type (16-VQFN Exposed Pad, 16-QFN 4x4)
• Identical mounting type (Surface Mount)
• Identical control interface (Serial)
• Identical standards compliance (SMPTE)
• Identical application domain (Professional Video)
• Identical moisture sensitivity level (MSL 3, 168 Hours)
• Identical export classification (ECCN 5A991B1)
• Identical tariff classification (HTSUS 8542.39.0001)
• Enhanced compliance status (ROHS3 Compliant, REACH Unaffected)

The GS2988-INE3 is actively manufactured and maintains full compatibility with the electrical and mechanical specifications of the obsolete GS2978-CNE3.

Parameter Comparison

Engineering Selection Recommendations

The GS2988-INE3 is the appropriate substitute for the obsolete GS2978-CNE3. Selection is based on:

• Identical mechanical compatibility (16-QFN 4x4 package, surface mount configuration)
• Identical electrical interface specifications (serial control, SMPTE standard compliance)
• Identical supply voltage range (3.135V ~ 3.465V)
• Identical functional classification (video cable driver for professional applications)
• Enhanced regulatory compliance (ROHS3 Compliant, REACH Unaffected status)
• Active production status ensuring long-term availability and supply chain continuity

The GS2988-INE3 maintains full pin and functional compatibility with the GS2978-CNE3, enabling direct substitution in existing designs without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the GS2988-INE3 be used as a direct replacement for the GS2978-CNE3?

A: Yes. Both parts share identical package geometry (16-QFN 4x4), mounting type (surface mount), control interface (serial), supply voltage range (3.135V ~ 3.465V), and functional specifications for SMPTE-compliant professional video applications. Pin-for-pin compatibility is maintained.

Q: What is the primary reason for substitution?

A: The GS2978-CNE3 is classified as obsolete. The GS2988-INE3 is an active production part from the same manufacturer, ensuring continued availability and supply chain reliability.

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

A: The GS2988-INE3 carries enhanced compliance certifications (ROHS3 Compliant and REACH Unaffected status) compared to the GS2978-CNE3 (RoHS Compliant). Both maintain identical ECCN and HTSUS classifications.

Q: Is the packaging format identical?

A: Yes. Both parts use 16-VQFN Exposed Pad packaging in a 16-QFN (4x4) configuration with identical moisture sensitivity levels (MSL 3, 168 Hours).

Q: Are there any electrical parameter differences?

A: The supply voltage range (3.135V ~ 3.465V) is identical. Both parts operate under identical SMPTE standards for professional video applications with serial control interfaces.
