Please try more reliable code

CREATE BELOW FUNCTION

CREATE FUNCTION dbo.UFN_SEPARATES_COLUMNS(
 @TEXT      varchar(8000)
,@COLUMN    tinyint
,@SEPARATOR char(1)
)RETURNS varchar(8000)
AS
  BEGIN
       DECLARE @POS_START  int = 1
       DECLARE @POS_END    int = CHARINDEX(@SEPARATOR, @TEXT, @POS_START)

       WHILE (@COLUMN >1 AND @POS_END> 0)
         BEGIN
             SET @POS_START = @POS_END + 1
             SET @POS_END = CHARINDEX(@SEPARATOR, @TEXT, @POS_START)
             SET @COLUMN = @COLUMN - 1
         END 

       IF @COLUMN > 1  SET @POS_START = LEN(@TEXT) + 1
       IF @POS_END = 0 SET @POS_END = LEN(@TEXT) + 1 

       RETURN SUBSTRING (@TEXT, @POS_START, @POS_END - @POS_START)
  END
GO

AND Then try below code

DECLARE @STRING VARCHAR(20) ='1-668-333'
SELECT
  dbo.UFN_SEPARATES_COLUMNS(@STRING, 1, '-') AS VALUE1,
  dbo.UFN_SEPARATES_COLUMNS(@STRING, 2, '-') AS VALUE2,
  dbo.UFN_SEPARATES_COLUMNS(@STRING, 3, '-') AS VALUE3
