Principal Component Analysis technique is the most used method for Factor
analysis.  However there are other methods like, Unweighted least squares,
Generalized least square, maximum likelihood, principal axis factoring etc.
I don't think the two are synonymous in true sense.  However if someone
mentions that thay have used PCA (principal Component Analysis) it is true
that they are talking about Factor Analysis but not necessarily vice-versa.
Hope it helps.
