Procurement Notes
This component is officially marked as obsolete and no longer manufactured by NXP USA Inc. Verification of availability should focus on surplus or distributor stock rather than direct production orders. Confirm the specific package variant and revision level against legacy documentation before integration into new designs.
Selection Notes
Designers seeking current alternatives should evaluate newer NXP LED drivers with similar pin counts and output capabilities. Consider factors such as updated efficiency standards, enhanced protection features, and long-term supply stability when selecting replacement parts for existing products.
Part Context
The PCA9622 series belongs to NXP's portfolio of LED controllers designed for low-power applications. This specific part number represents the tape-and-reel packaging version of the PCA9622, facilitating automated assembly processes in manufacturing environments.
Replacement Considerations
NXP recommends the PCA9955BTWJ as a manufacturer-recommended substitute. Verify compatibility regarding pinout, electrical specifications, and software configuration tools before transitioning to this alternative.
