      Reference numbers the Federal Logistics Information System records against the same National Stock Number. A supply-catalog cross-reference, not an engineering-approved interchangeability: confirm against the controlling drawing or spec before substituting. Only equivalents marked cited have a manufacturer or government document, linked with each.
