I've read the datasheet and looked at the NXP product page and I'm still none the wiser.
What is the difference between MPXH6400AC6T1 and MPXHZ6400AC6T1 ? i.e. what does the Z in the part number mean?
They both have upwards facing nipples, both are identical electrically, both are absolute 400kPa, both are tape and reel?
I did a search on the letter Z in the datasheet and the only occurences are on the first page.
From Farnell, the Z part is a few pence cheaper? Why?
