DPFE EGR Pressure Feedback Sensor

[BTR]

2000 Explorer 4.0L SOHC JOB1 Engine. My OEM DPFE is stamped F77E-9J460-AB. I just installed a new DPFE whose box is stamped F77Z-9J460-AB. My CEL is still on. Usually the CEL turns off immediately when the DPFE is working, i.e., a code reset is not required in order for the CEL to turn off. Based on the stamps I listed, is the "Z" a problem?

It's no biggie I've successfully interchanged aluminum and plastic dpfe's from Lincolns Taurus's and put them on my ex's and they were working fine
