The tube packaging option was discontinued last year. The PCA9555DWR is exactly the same chip packaged on a reel.

Kapil,

I assume you are talking about packaging options Clemens' response answers this question.

If your question is not directed to the difference between PCA9555DW and PCA9555DWR, then I can say that PCA9555DWR is still in the ACTIVE status with no business case to stop production of this part. The longevity of this part looks to be secure for the upcoming years due to customer usage of this device.

If you are concerned with using an old device, consider the TCA9555 which is the pin to pin compatible upgrade to the PCA9555 device.

Regards,

Tyler

The TCA9555 is not available in the SOIC package.

If you ever change the board, consider switching to the (T)SSOP or VQFN package so that you have more options.

Hi Tyler,

No not about package, I am talking about the part. I am using this part (PCA9555DW) in my design. So clarify if this part is in production or end of life?

If this part is obsolete then let me know the drop-in replacement for this part PCA9555DW. i need to revise the PCB acordingly.

Hi Kapil,

PCA9555DW is in production an ACTIVE.

Part is not obsolete, but it is an older part. Consider making the switch to TCA9555 in a different package type.
