The Electronic Industries Alliance (EIA; until 1997 Electronic Industries Association) was a standards and trade organization composed as an alliance of trade associations for electronics manufacturers in the United States. They developed standards to ensure the equipment of different manufacturers was compatible and interchangeable. The EIA ceased operations on February 11, 2011, but the former sectors continue to serve the constituencies of EIA.[1]


In 1924 United States-based radio manufacturers formed a trade group called the Associated Radio Manufacturers. Later that same year, the group renamed itself the Radio Manufacturers Association (RMA). Over time, new electronic technologies brought new members and name changes, including Radio Television Manufacturers Association (RTMA) (1950), Radio Electronics Television Manufacturers (RETMA) (1953) and Electronics Industries Association (EIA) (1957). The group renamed itself for the last time in 1997, when the Electronics Industry Association became the Electronics Industries Alliance (EIA), reflecting the changing membership of the group, including non-manufacturer members.

The organization's headquarters were in Arlington, Virginia. The EIA divided its activities into the following sectors:

The EIA announced in 2007 that it would be dissolved into its constituent divisions,[2] and transferred operations soon after. The Alliance formally ceased to exist on February 11, 2011.[1] EIA designated ECA to continue to develop standards for interconnect, passive and electro-mechanical (IP&E) electronic components under the ANSI-designation of EIA standards. All other electronic components standards will be managed by their respective sectors. ECA is expected to merge with the National Electronic Distributors Association (NEDA) to form the Electronic Components Industry Association (ECIA). However, the EIA standards brand will continue for IP&E standards within ECIA.[3]

EIA standards[edit]

With the changing names of the EIA, the naming convention of the standards was also adapted. For example, a standard defining serial communication between computers and modems e.g. was originally drafted as a recommended standard, thus the "RS" RS-232. Later it was taken over by the EIA as EIA-232. Later this standard was managed by the TIA and the name was changed to the current TIA-232. Because the EIA was accredited by ANSI to help develop standards in its areas, the standards are often described as e.g. ANSI TIA-232 (or formerly as ANSI EIA/TIA-232). As currently authorized, any ANSI standard designated at ANSI EIA-xxx is developed and/or managed by ECA (and, in the future, ECIA).
