hi
i have a radio which use CXA1619BS IC.problem is radio selectivity.strong local stations didn't let to receive adjacent channels so i want to use another filter
i extract schematic from radio board and i want to replace SFU455B ceramic filter with CFWLA455KGFA-B0
can i do this?and just replace new filter with the old filter? or circuit need chanes?
here is extracted schematic(just IF parts)(NPN transistor is S9018):

here is SFU455B datasheet:

here is CFWLA455KGFA-B0 datasheet:
