845-090-544-208

Edgeboard Connectors Overview

The EDAC Inc. model 845-090-544-208 is a standard card edge connector from the 845 High Temp series, designed for panel mounting applications. It features a single row of 90 positions with a .100 inch (2.54 mm) contact spacing. The connector utilizes solder pin termination and gold-plated copper alloy contacts to ensure reliable electrical performance. Constructed with a diallyl phthalate (DAP) insulator, it supports a PCB thickness of 1.57 mm. The component is rated for a current of 3 A per contact and offers an insulation resistance of 5 GOhms. It operates within a temperature range of -40 C to +125 C.

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with existing board layouts. Ensure that the solder pin termination style matches the target PCB fabrication capabilities. Confirm that the operating temperature requirements align with the specified -40 C to +125 C range before finalizing procurement decisions.

Edgeboard Connectors Selection Notes

Select this connector when a robust, high-temperature solution is required for vertical or straight panel mounting. The 90-position count suits applications needing substantial I/O density in a single row. Verify that the 1.57 mm PCB thickness specification matches the design constraints. Consider the DAP material properties for environmental stability during selection.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 series, which specializes in high-temperature card edge connectors. The series is engineered for rugged applications where standard connectors may fail due to thermal stress. The 845-090-544-208 variant specifically addresses needs for higher pin counts while maintaining the series' durability standards.

Edgeboard Connectors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other EDAC 845 series models only if pin count and termination type match exactly.
