Part Number: TL432LI
My client wants to use TL432LI for LA431, IKA parameters are as follows, will there be any side effects?
TL432LI IKA: 1mA~15mA
LA431 IKA: 0.3mA~100mA
I cannot comment on side affects without knowing the application and schematic. In most situations the TL431LI can be a drop in replacement but if they require lower Ika then they can use a ATL431LI.
Can you give us more information on the use case?
Is this being used as a reference to an ADC or as optocoupler feedback in PD?

If you are using the TL431, check out the new TL431LI and its low Iq counterpart ATL431LI for improved system performance in a p2p package.
