The part number is A19390, and several sources link it to the National Stock Number 5998-01-424-6739, identifying it precisely as a Circuit Card Assembly produced by Avtron Aerospace Inc. Some listings reference A19390 in REV F, signaling a revision level that preserves the original form factor and connector layout while updating internal components. Marketed as a replacement part, the A19390 is used to restore or refurbish Avtron equipment that relies on this circuit board to manage a subassembly or subsystem within the device. As a circuit board, it consolidates circuitry onto a single printed circuit board with mounted components and edge connectors that interface with the surrounding hardware and backplane, enabling targeted functionality within supported Avtron systems. Because exact electrical specifications, pinouts, mounting dimensions, and compatibility can vary by model and revision, prospective buyers should confirm the precise fit for their Avtron device and reference the board’s revision level (for example REV F) to ensure proper integration with the intended system.\u003c\/p\u003e\u003c\/div\u003e","brand":"AVTRON","offers":[{"title":"New","offer_id":51660438307118,"sku":null,"price":179.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_2f449b68-0a33-48c7-94cf-f6c2488c704c.jpg?v=1769537570","url":"https:\/\/plgautomation.com\/products\/avtron-a19390-circuit-board","provider":"PLG Automation ","version":"1.0","type":"link"}
