Alternate part number
An alternate part number is a different part number approved as interchangeable with the one requested, for example a newer dash number, an OEM equivalent, or a PMA part. Interchangeability is defined by the manufacturer's Illustrated Parts Catalog and related documentation, never by guesswork. Checking alternates is a routine quoting step, because a desk that only searches the exact number requested misses stock it could legitimately offer.
