Product Number: LT3502, LT8609
I'm designing a circuit and I chose LT3502 and LT8609 as my power converter. However, these parts are recommended XAL5020-222MEB and LQH43CN6R8M03L as inductor. However, the mentioned parts are obsolete and NRND. Can you please confirm if I can use 78438366022 as an alternate to XAL5020-222MEB;
