No Federal Reserve Notes or any other related forms of US paper money have ever carried an expiration date. They can be spent at face value no matter how old they are. It might not be a good idea to do that, though, because many old bills are worth more than face value to a collector or dealer.
Since 1914, gold certificates have been the only US bills officially removed from circulation. That action was taken in 1933 when the US went off the gold standard due to the Depression.
The Federal Reserve Charter does not contain an expiration date for various reasons. However, the charter is subject to revocation by Congress.
