Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, housing material variants, and mounting hardware configurations. Ensure compatibility with target PCB panel thickness specifications before procurement. Cross-reference RoHS compliance status with the latest manufacturer declarations to meet regulatory requirements for the intended deployment region.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with a 3.96 mm pitch is required for panel-mounted installations. Confirm that the application environment stays within the specified -40°C to +105°C operational range. Verify that the target circuit board thickness aligns with the 1.57 mm design parameter to ensure proper mechanical engagement and electrical continuity during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, providing modular solutions for high-reliability interconnect needs. The 305 series is characterized by its robust thermoplastic construction and consistent 3.96 mm spacing, suitable for demanding industrial and commercial electronic assemblies requiring durable signal transmission.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-020-555-504 and 305-020-500-203, provided they match the required 20-position count and 3.96 mm pitch. Verify that alternative suffixes correspond to identical mounting styles and contact materials before substitution.
