Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 66-position count and 0.156-inch pitch specifications before procurement. Confirm that the target application supports the vertical panel mounting orientation and the specified board thickness of 0.062 inches. Ensure environmental requirements align with the stated operating temperature range and RoHS3 compliance status to guarantee compatibility with assembly processes.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female interface is required for vertical panel integration. The 0.156-inch pitch accommodates standard board layouts while the 66-position capacity provides substantial connectivity. Verify that the thermoplastic insulation and gold contact finish meet the electrical and durability needs of the intended operational environment compared to alternative series options.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various position counts and mounting configurations. The series utilizes a consistent 0.156-inch contact spacing across models. The 305-066-555-503 variant specifically addresses applications requiring a higher pin count within the dual-row format while maintaining the standard dimensional profile associated with the product line.

Edgeboard Connectors Replacement Considerations

Cross-reference other 305-series parts with identical 66-position counts and dual-row female configurations. Ensure replacement units maintain the same 0.156-inch pitch and vertical mounting orientation to preserve mechanical fit.
