Specialized Procurement Notes

This component is officially listed as End of Life or No Longer Manufactured by NXP Semiconductors. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm the specific suffix /G,118 matches their design requirements, as this variant may have different lead times or availability compared to other PCA9559 versions. Due to its discontinued status, long-term supply stability cannot be guaranteed.

Specialized Selection Notes

Designers requiring this part should evaluate alternative NXP I2C interface solutions due to the End of Life status. Verify that the 3V to 3.6V supply voltage range meets system specifications. Ensure the 20-TSSOP footprint is compatible with existing PCB layouts. Consider the /G,118 suffix specifics regarding environmental compliance if sourcing from secondary markets.

Specialized Part Context

The PCA9559 series includes multiple variants such as the PW,112 and PW,118. The /G,118 suffix indicates a specific manufacturing lot or environmental compliance version within the TSSOP20 package family. While functionally similar to other PCA9559 parts, the /G designation often relates to halogen-free or specific RoHS compliance certificates. Cross-referencing datasheets is essential to confirm pinout and electrical characteristics match the design intent.

Specialized Replacement Considerations

No direct public substitute part numbers are confirmed for the PCA9559PW/G,118. Engineers should consult NXP documentation for recommended obsolescence replacements within the PCA95xx family.
