Procurement Notes

Verify the specific suffix 'X' indicates industrial grade specifications compared to standard commercial variants. Confirm that the 'OCT' packaging designation aligns with reel or cut tape requirements for automated assembly processes. Ensure compatibility with existing board layouts regarding the 100-SMD footprint dimensions.

Selection Notes

Select this component when dual-band Wi-Fi and Bluetooth are required in a single form factor. The industrial temperature range distinguishes it from commercial alternatives like the WL1831MODGBMOCT. Consider the 2x2 MIMO capability if higher throughput and reliability are necessary for the application design.

Part Context

This module belongs to the Texas Instruments WiLink 8 family, designed for high-performance wireless connectivity.
