Pricing and stock are confirmed at quote time against an RFQ; lead time is quoted per order.
No direct replacement or second-source alternate is listed. The CYPD2122-24LQXIT is a different device (USB Type-C controller with Cortex-M0 and 32 KB Flash) and is not a functional equivalent for the FX3S USB 3.0 peripheral controller. For dual-sourcing, qualify a second FX3S variant from the same series.
The CYUSB3035-BZXI is rated for -40°C to 85°C, which qualifies it for industrial environments such as factory automation, outdoor telecom, and test equipment.
