Edgeboard Connectors Procurement Notes

Verify the specific manufacturer datasheet for the 842-056-542-101 to confirm current RoHS compliance status and any recent product change notifications. Ensure that the receiving facility's handling procedures align with the specified operating temperature range and mechanical stress limits defined in the official documentation before deployment.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 56-position card edge interface is required for panel-mounted systems. The 2.54 mm pitch and 1.37–1.78 mm board thickness compatibility are critical constraints. Verify that the application environment remains within the -40°C to +125°C operational window and that wire wrap termination methods are utilized for electrical connections.

Edgeboard Connectors Part Context

This connector belongs to the EDAC standard card edge series, specifically engineered for robust vertical mounting solutions. The 842 series designation indicates a single-row receptacle format optimized for high-density interconnects. The model integrates durable PPS housing to maintain structural integrity under thermal cycling conditions common in industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

No publicly confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 56-position count, 2.54 mm pitch, single-row orientation, and wire wrap termination style. Any alternative must support the same board thickness tolerance and environmental rating.
