I did some part # checking Toyota/Lexus made a total mess of this, multiple parts change up multiple times. Depending on the year and model you may or may not get the same pressure rating.

15.6 vs 16 is a small difference and the stated pressure is when the relief valve kicks in. The working psi is typically a safe distance away.
I would measure the diagram of the seal and the locking mechanism [it should not fit loose].
