Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating specifications, and insulation material properties. Ensure compatibility with target PCB thickness tolerances before procurement. Cross-reference manufacturer datasheets for precise mechanical dimensions and mating force requirements to prevent assembly issues.

Edgeboard Connectors Selection Notes

Select this model when a dual-row female interface is required for straddle mounting on standard thickness boards. Consider the 0.156-inch pitch and vertical orientation constraints. Evaluate thermal operating ranges and insulation resistance specifications against environmental conditions. Confirm that the low-profile body fits within available spatial 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 mounting styles. The 305-052 variant specifically addresses needs for moderate-density connections requiring robust mechanical retention through straddle mounting techniques.

Edgeboard Connectors Replacement Considerations

Consult official EDAC cross-reference guides for verified substitute part numbers. Generic equivalents may not match critical dimensional tolerances or contact plating specifications required for reliable performance.
