W1 and W2 are both 2 pin headers but different parts
W1 is according to EDA-04509-V1-0_pcb-mat.xls a HARWIN M20-9990246 (2 Contacts SIL Vertical Pin Header, Pitch 2.54mm, Mating Height 6.1mm, Insulator 2.54mm, Finish Tin).
W2 is according to EDA-04509-V1-0_pcb-mat.xls a SAMTEC MTLW-102-07-L-S-250 (2 Contacts, Pitch 2.54mm, Single Row Through Mount Straight Header (Post Lead = 6.35mm, Tail Lead 3.05mm, Insulator 1.52mm))
