Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the dual-row layout aligns with the design requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 44 positions is required. The 3.96 mm pitch accommodates standard board layouts while the 1.57 mm thickness tolerance ensures proper engagement. Consider the vertical mounting angle and panel mount style for enclosure integration. Verify that the 5 A current rating meets the electrical load requirements of the application circuitry.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting options. The series is characterized by its robust construction and standardized dimensions. Similar models in the series include variants with different row counts or termination styles, allowing for flexible design integration across multiple product lines within the same family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include part numbers such as 305-044-520-558 and 305-044-520-202, which share identical mechanical specifications and positioning. Verify that any alternative part maintains the same 44-position count and 3.96 mm pitch to ensure physical compatibility.
