Edgeboard Connectors Procurement Notes

Verify the specific suffix '212' against official EDAC documentation to confirm the exact termination style and flange configuration. Ensure compatibility with the target PCB thickness range of 0.054 to 0.070 inches. Confirm that the right-angle panel mount orientation aligns with the mechanical assembly requirements. Cross-reference the 72-position count with the design schematic to prevent pinout mismatches during integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for high-density applications within the 333 series family. The 3.96 mm pitch suits designs needing fewer connections than finer pitches but higher capacity than smaller formats. Consider the right-angle form factor for constrained panel layouts. Verify that the 3 A current rating meets the electrical load requirements of the specific circuit traces.

Edgeboard Connectors Part Context

This part belongs to the EDAC 333 series, which specializes in standard card edge connectors. The series is characterized by its 0.156-inch pitch and durable construction suitable for industrial environments. The 333-072-521-212 variant specifically addresses needs for dual-edge connectivity with a 72-position footprint, offering a balance between density and mechanical reliability for panel-mounted installations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and pitch, such as the 333-072-521-212 equivalent configurations. Verify that any alternative maintains the dual-edge female interface and right-angle panel mount style. Ensure the replacement matches the 0.156-inch pitch and compatible PCB thickness specifications to guarantee mechanical fit.
