Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, flange dimensions, and mounting variations. Ensure compatibility with target PCB hole sizes and panel cutouts before procurement. Cross-reference RoHS compliance status with the latest manufacturer datasheet to meet regional regulatory requirements. Confirm availability through authorized distributors as supply levels may fluctuate.

Edgeboard Connectors Selection Notes

Select this model when a 20-position dual-row connector with 3.96 mm pitch is required for panel mounting applications. Consider the 1.57 mm board thickness constraint and verify that the 5 A current rating meets circuit demands. Evaluate the -40°C to +105°C operating range against environmental conditions. Compare with other 305 series variants if different row counts or termination styles are needed.
