Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination style. Ensure compatibility with the target printed circuit board thickness of 1.57 mm. Confirm that the gold plating specification meets the required environmental durability standards for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required. Consider the vertical panel mount style and solder pin termination method for assembly constraints. Evaluate the 5 A current rating and operating temperature range against the system's thermal and electrical load requirements to ensure long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options. The 305-026-555-258 specifically denotes a 26-position dual-row variant. This series is widely used in modular electronic systems requiring robust mechanical and electrical connections between edgeboard connectors and headers.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-026-555-208 or 305-026-555-201 if different termination or housing variations are needed. Verify that substitute parts maintain the same 3.96 mm pitch and 26-position dual-row layout to ensure mechanical fit.
