Procurement Notes

This component has reached end-of-life status and is no longer manufactured by NXP Semiconductors. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Engineers should prioritize evaluating the documented replacement parts to ensure long-term supply chain stability and design continuity.

Selection Notes

Designers requiring this specific functionality must account for the component's discontinuation. Selection should focus on verifying pin compatibility and electrical parameters against the recommended substitute, PCA9952TW/Q900,118. Ensure that the alternative meets all system requirements regarding channel count, current drive capability, and interface protocols before finalizing the bill of materials.

Part Context

The PCA9955 belongs to NXP's PCA995x series of LED drivers designed for high-performance lighting applications. This series is characterized by its ability to handle multiple channels with individual PWM control. The TW/Q900 suffix indicates the specific package type and tape-and-reel packaging configuration used for automated assembly processes in manufacturing environments.
