Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm pin count, contact plating, and mounting style match the design requirements. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the dual-edge female termination type aligns with the system's mechanical constraints. Cross-reference the manufacturer datasheet for environmental ratings and compliance certifications before finalizing the procurement order.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection with 76 positions is required in a dual-row arrangement. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the vertical mounting orientation and solder pin termination for panel or PCB integration. Evaluate the operating temperature range of -40°C to +105°C against the application environment to ensure long-term reliability under thermal stress.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series is characterized by its versatility in position counts and mounting styles, catering to various industrial and commercial applications. The 305 series connectors are known for their low profile and durable construction, making them suitable for space-constrained designs requiring reliable electrical connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with similar position counts and pitch, such as the 305-072-555-203 or 305-080-555-203, provided the mechanical fit and electrical specifications remain compatible. Verify that any alternative maintains the dual-edge female configuration and gold plating to ensure equivalent performance characteristics.
