Frequently Asked Questions (FAQ)

Q: Can KSZ9477STXI-TR be used as a direct replacement for KSZ9567STXI-TR?

A: Yes. Both parts share identical electrical specifications, package type (128-TQFP-EP 14x14), supply voltage range (1.8V to 3.3V), operating temperature range (-40°C to 85°C), interface protocols (I2C, SPI), and compliance certifications (ROHS3, REACH). The primary difference is packaging format: KSZ9567STXI-TR uses Tape & Reel, while KSZ9477STXI-TR uses Cut Tape & Digi-Reel®.

Q: What is the difference between STXI and RTXI variants?

A: The provided data specifies both STXI and RTXI variants for KSZ9567 and KSZ9897 base product numbers. All variants maintain identical electrical and mechanical parameters. Packaging format differs: STXI variants are supplied in Tape & Reel or Cut Tape & Digi-Reel®, while RTXI variants are supplied in Cut Tape & Digi-Reel® format.

Q: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the identical 128-TQFP Exposed Pad package with 14x14mm dimensions, enabling direct PCB layout compatibility without redesign.

Q: What is the Moisture Sensitivity Level (MSL) rating, and why does it matter?

A: All parts carry MSL 3 (168 Hours) rating, indicating the component can be exposed to ambient conditions of 30°C and 85% relative humidity for up to 168 hours before soldering. This specification is critical for supply chain handling and assembly process planning.
