• High-density electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required flange features and termination style. Confirm compatibility with the target PCB thickness of 1.57 mm. Ensure the polarizing key requirements align with the system design specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a 44-position dual-row interface is required with a 3.96 mm pitch. Consider the 5 A current rating and high-temperature tolerance for demanding environments. Verify that the panel-mount vertical configuration fits the mechanical enclosure constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations. The 305-044-521-208 specifically provides a 44-position solution with gold-plated contacts and thermoplastic insulation.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-044-520-558 or 305-044-521-201 for similar specifications. Verify that alternative parts maintain the same 3.96 mm pitch and 1.57 mm board thickness compatibility.
