Product details

What this Ethernet switch is and where it fits

The NXP SJA1105SELY is an automotive-grade Ethernet switch IC controlled over an SPI host interface. It complies with IEEE 802.3 standards and is qualified to AEC-Q100, making it suitable for in-vehicle networks that must survive under-hood temperatures from -40°C to 125°C. The 159-LFBGA package (12x12 mm) keeps the footprint compact for ECU integration.

Lifecycle and sourcing reality

The SJA1105SELY carries an Active lifecycle status and is ROHS3 compliant. No last-time-buy or end-of-life notice is in effect, so it remains a safe choice for new production builds.

Frequently asked questions

Is SJA1105SELY AEC-Q100 qualified?

Yes, the SJA1105SELY is AEC-Q100 qualified, confirming its suitability for automotive applications.

Is SJA1105SELY RoHS compliant?

Yes, the SJA1105SELY is ROHS3 compliant.

Can SJA1105SELY replace SJA1105SEL?

The SJA1105SELY is a variant of the SJA1105SEL family. The 'Y' suffix typically indicates a specific package or tape-and-reel option. Pin compatibility should be verified against the respective datasheets, but functionally they share the same Ethernet switch core.

What is the difference between SJA1105SELY and SJA1105SEL?

The SJA1105SELY is listed with a Tape & Reel (TR) and Cut Tape (CT) packaging option, while the SJA1105SEL may differ in packaging. Both are automotive Ethernet switch ICs with the same core function.
