ATL432LI: working in noisy environment

Part Number: ATL432LI
Other Parts Discussed in Thread: ATL431LI, TL431

We're wondering to know if ATL431LI with less IKA current in noisy environment is more sensitive than TL431 with higher IKA current? 

Since customer application is in very noisy environment as motor applilcation..., RD would like to know if TL431 is better to use in noisy enviroment. Could you help to suggest what is good one from noisy's point of view! thanks.
