good!
IEC61347-2-2 A1[2006-06-04] clause 8.2
In the case of capacitors which are connected between SELV-equivlent output and primary circiuts,one capacitor Y1 or two capaciors Y2 in series with the same value specified and tested according to Tables 2 and 3 respectively of IEC 60384-14 are to be used.
从这段可以知道是可以使用1个Y1电容来代替2个Y2电容的
