Issues with Inhibit functionality on PTH08T240WAZ

Hello,

Before getting into the circuit implementation, I'd like to know if there is any inherent difference between these parts:

  1. PTH08T240WAZ-411474V
  2. PTH08T240WAZ-531830V

I have two identical circuit implementations on two different boards, and I am able to enable/disable the supply using part #1. On the second board, I notice that the PN is identical, but there is a trailing sequence that is different than that of board #1.

Does anyone know if there are any inherent differences between the two parts above? I can't seem to find any information on the datasheet or the TI website.

Thanks!
