+ is a reserved character. From RFC 3986 section 2.2 "Reserved Characters":

"""
   Percent-
   encoding a reserved character, or decoding a percent-encoded octet
   that corresponds to a reserved character, will change how the URI is
   interpreted by most applications.
"""

From RFC 2616 section 3.2.3 "URI Comparison" (note that RFC 3986
supersedes the referenced RFC 2396):

"""
   Characters other than those in the "reserved" and "unsafe" sets (see
   RFC 2396 [42]) are equivalent to their ""%" HEX HEX" encoding.
"""

So, no, those two are not equivalent. "+" is a reserved character, so it
cannot be translated to or from "%2B" without changing the URL's meaning.
