Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or verified platforms. Confirm that the specific suffix matches the required pin count and termination style. Check for RoHS3 compliance documentation if environmental regulations apply. Ensure the receiving facility can handle the manufacturer's standard lead time. Validate that the package quantity aligns with project requirements before finalizing orders.

Edgeboard Connectors Selection Notes

Select this model when a vertical, dual-row card edge interface is required. The 3.96 mm pitch accommodates standard edge boards within the specified thickness range. Gold plating ensures longevity in demanding operational cycles. Consider the 5 A current rating for power distribution needs. Verify compatibility with polarizing keys if system security against misalignment is necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and termination options tailored for diverse industrial and commercial applications. The 305-018 variant specifically addresses the need for 18-position connectivity in a compact vertical form factor, supporting both signal and low-power data transmission tasks.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series parts sharing identical pitch and row configuration. Verify mechanical dimensions and electrical ratings match exactly. Ensure alternative models support the same solder lug termination type. Confirm that substitute components maintain the required gold plating specifications for contact reliability.
