306-028-420-178

Overview

The EDAC Inc. 306-028-420-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight installation angle. It features 56 positions arranged in a dual female configuration with a 0.156-inch (3.96 mm) contact spacing. The connector utilizes copper alloy contacts with tin plating and terminates via solder eyelets. Constructed with a green thermoplastic polyester insulator, it supports a current rating of 5 A.

Feature Summary

• Dual-edge female receptacle design for non-specified card edge applications
• Through-hole termination using solder eyelet connection method
• Copper alloy contacts with tin surface plating for reliable conductivity
• Green thermoplastic polyester housing material

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• General electronic assemblies needing high-density signal routing

Procurement Notes

Verify the specific ordering suffix to confirm contact plating and housing color variations. Confirm that the tin-plated variant meets environmental requirements if lead-free compliance is mandatory. Ensure the through-hole solder eyelet termination style aligns with the target PCB fabrication capabilities and assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required for through-hole assembly. The tin-plated contacts offer cost-effective conductivity suitable for general-purpose applications. Verify that the 56-position count matches the circuit design needs and that the straight mounting orientation fits within the available mechanical envelope constraints.

Part Context

This part belongs to the EDAC 306 series, which provides standard card edge connectors with 0.156-inch spacing. The series offers various position counts and termination styles to support diverse electronic interconnection requirements across industrial and commercial sectors.

Replacement Considerations

Cross-reference with other 306-series variants for different position counts or plating options. Verify compatibility with existing PCB layouts and mating card edge specifications before substituting.
