305-084-500-268

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-268 is a standard card edge connector featuring 84 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). Designed for dual-edge mating, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The component utilizes gold-plated copper alloy contacts to ensure reliable signal transmission and corrosion resistance. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing electrical insulation and mechanical stability for panel or PCB mounting applications.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact plating thickness, termination style, and housing color variations. Ensure compatibility with existing PCB layout dimensions, particularly regarding the 1.57 mm board thickness constraint. Cross-reference the 84-position count and 3.96 mm pitch with schematic requirements before finalizing procurement orders to prevent integration errors.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge interface is required for 84-position connectivity with a 3.96 mm pitch. The 5 A current rating and wide operating temperature range suit environments with moderate thermal stress. Consider the vertical or straight mounting orientation options available within the series if panel integration is necessary. Confirm that the target application does not require specialized high-frequency shielding beyond standard card edge capabilities.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose electronic interconnections. The series offers various position counts and termination styles to accommodate diverse board designs. The 305-084-500-268 variant specifically addresses high-density applications requiring dual-edge access while maintaining standard mechanical tolerances for widespread industry adoption.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 84-position counts and 3.96 mm pitch, such as the 305-084-500-201, provided the termination style matches the assembly requirements. Verify that any alternative maintains the same 1.57 mm board thickness acceptance and gold plating specifications to ensure functional equivalence.
