305-080-556-268

Edgeboard Connectors Overview

The EDAC Inc. 305-080-556-268 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 80 positions with a 0.156-inch (3.96 mm) pitch and supports PCB thicknesses between 0.054 and 0.070 inches (1.37–1.78 mm). The contacts are gold-plated copper alloy with a 10.0 µin (0.25 µm) thickness, utilizing semi-spring terminals. Rated for 5 A current, it operates within -40°C to +105°C. The housing is green thermoplastic polyester, and it employs panel mount vertical solder pin termination.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified card types
• Gold-plated copper alloy contacts with semi-spring terminal design
• Thermoplastic polyester insulation housing
• Panel mount vertical installation style

Edgeboard Connectors Applications

• Panel-mounted electronic interconnects
• Card cage systems requiring dual-edge access
• Industrial control board interfaces
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating thickness, flange characteristics, and termination type. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Confirm that the application environment remains within the -40°C to +105°C operating temperature limits. Check for RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-density 80-position dual-edge interface is required for panel mounting. The 3.96 mm pitch accommodates standard card edge layouts. Verify compatibility with the mating card's thickness and the available panel space for the vertical header profile. Consider the thermal rating and current capacity relative to the signal load requirements of the specific circuit design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options for dual-edge applications. The 305-080 variant specifically provides an 80-position configuration, distinguishing it from lower-count models like the 305-048 or higher-count variants in the same family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing the same 80-position count and dual-edge female specification. Verify identical pitch, PCB thickness tolerance, and mounting style before substitution. Consult the manufacturer's ordering guide for direct equivalents with modified termination or flange features.
