They are different Jimmy. Heres some info lifted straight from wiki- Mash ingredients
Crystal malts are prepared separately from pale malts. They are high-nitrogen malts that are wetted and roasted in a rotating drum before kilning. They produce strongly sweet toffee-like flavors and are sufficiently converted that they can be steeped without mashing to extract their flavor. Crystal malts are available in a range of colors, with darker-colored crystal malts; that is, those kilned at higher temperatures, producing stronger, more caramel-like overtones. Some of the sugars in crystal malts caramelize during kilning and become unfermentable; hence, addition of crystal malt will increase the final sweetness of a beer. They contain no enzymes. ASBC 50-165/EBC 90-320; the typical British crystal malt used in pale ale and bitter is around ASBC 70-80.
Pilsner malt, the basis of pale lager, is quite pale and strongly flavored. Invented in the 1840s, Pilsner malt is the lightest-colored generally-available malt, and also carries a strong, sweet malt flavor. Usually a pale lager's grain bill consists entirely of this malt, which has enough enzymatic power to be used as a base malt. The commercial desirability of light-colored beers has also led to some British brewers adopting Pilsner malt (sometimes described simply as "lager malt" in Britain) in creating golden ales. In Germany, Pilsner malt is also used in some interpretations of the Klsch style. ASBC 1-2/EBC 3-4, DP 60 Lintner.
