Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact mechanical dimensions and contact specifications. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status through official documentation prior to procurement to meet regulatory requirements.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for dual-row card edge interfaces. The 3.96 mm pitch accommodates specific spacing requirements not met by finer pitches. Verify that the application environment falls within the operational temperature range and that the gold-plated contacts meet the necessary conductivity standards.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in panel mounting styles and compatibility with various PCB thicknesses. The 305 series is widely utilized across industrial and specialized sectors where reliable, high-cycle connectivity is essential for system performance.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants sharing identical pitch and row count but differing in housing color or guide style. Ensure substitute parts maintain the same 1.57 mm PCB thickness tolerance and vertical mounting orientation to preserve mechanical fit.
