Edgeboard Connectors Procurement Notes

Verify that the specific suffix 278 corresponds to the required flange characteristics, such as threaded inserts or diameter specifications, as these details define the mechanical mounting configuration. Confirm compliance with RoHS3 standards and ensure the selected variant matches the intended PCB thickness tolerance of 1.37mm to 1.78mm for proper engagement.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-row interface is required for vertical panel mounting. Ensure the design accommodates the 0.156-inch pitch and supports the necessary polarizing key integration. Verify that the application environment remains within the specified operating temperature range of -40°C to +105°C for reliable performance.
