YINGHUA KSZ9031RNXCA Ethernet IC QFN-48-EP semiconductor

YINGHUA KSZ9031RNXCA Ethernet IC

The YINGHUA KSZ9031RNXCA is a new Ethernet integrated circuit packaged in a QFN-48-EP footprint. It functions as a physical-layer transceiver for wired network connections in electronic designs. Engineers and procurement specialists source this component for manufacturing or repairing network-enabled hardware. The part entered the manufacturer listing on 21 February 2025.

Suits PCB designs needing a 48-pin Ethernet PHY

This component suits hardware developers implementing wired Ethernet on a printed circuit board with space for a QFN-48-EP package. It is not suitable for projects requiring a different pin count, a ball-grid array package, or an integrated MAC controller. Buyers needing managed switch functionality or multi-port integration in a single die should evaluate alternative devices.

QFN-48-EP package with 48 pins

The decisive specification is the QFN-48-EP package providing 48 connection pads including an exposed thermal pad. This footprint dictates the PCB land pattern, solder stencil design, and thermal dissipation path. Verify the package outline against your board layout before ordering, as pin-compatible substitutes in other packages will not fit the same pads.
