Sambhu,
Please dont be so formal! hi hi
Here is some info.
Quadrature coils / ceramic discriminators for NBFM receiver chips

MC3359 - 7MC-8128Z(TOKO) - 7MC-13546Z(TOKO) - CDA455C49 (Toko)
MC3361 - 7MC-8128Z(TOKO) - 7MC-13546Z(TOKO) - CDA455C49 (Toko)
MC3362 - 680uf/180pf
MC3371 - Quad Coil TOKO 2A6597 HK (10 mm) or 7MC–8128Z (7 mm) - CBD455C16 (Murata)
MC3372 - Quad Coil TOKO 2A6597 HK (10 mm) or 7MC–8128Z (7 mm) - CBD455C18 (Murata)
