Edgeboard Connectors Procurement Notes

Verify the specific suffix against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB card thickness within the 1.37 mm to 1.78 mm range. Confirm that the 5 A current rating meets system requirements under maximum operating temperature conditions of +105°C. Check for RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this component when a 70-position dual-edge interface is required for panel-mounted assemblies. The 3.96 mm pitch accommodates standard card edge layouts. Verify that the housing material, typically thermoplastic, suits the environmental exposure levels. Consider the vertical orientation for space-constrained panel installations. Ensure the polarizing key acceptance feature aligns with mechanical assembly constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for diverse electronic applications. The 305 series is characterized by robust construction suitable for industrial environments. Components in this line generally support solder pin termination and panel mounting styles.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for verified substitutes. Alternative parts must match the 70-position count, 3.96 mm pitch, and dual-edge female configuration. Verify identical current ratings and voltage withstand capabilities before substitution.
