306-018-421-178

Edgeboard Connectors Overview

The EDAC Inc. part number 306-018-421-178 is a standard card edge connector receptacle from the 306 series. It features 18 positions with a contact spacing of 0.156 inches (3.96 mm). The connector is designed for dual-edge, non-specified card types and utilizes female cantilever contacts. It supports a nominal printed circuit board thickness of 0.062 inches (1.57 mm) and employs solder pin termination. The housing is constructed from thermoplastic polyester, providing a low-profile insulator body suitable for panel mount installation.

Edgeboard Connectors Feature Summary

• Accepts nominal 0.062 inch (1.57 mm) thick PCBs
• Low profile insulator body design
• Female cantilever contact type for reliable engagement

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Communication equipment utilizing standard module form factors
• Consumer electronics assemblies needing high-density connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct contact plating, insulation material grade, and mounting flange configuration. Confirm that the target application requires the 0.156 inch pitch specification. Check regional availability status as distribution may vary by location. Ensure compatibility with the intended PCB thickness tolerance before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 3.96 mm pitch is required for dual-edge card applications. The 18-position count fits specific board width constraints. Verify that the panel mount style aligns with the enclosure design. Consider the thermal rating of the polyester insulator if operating in elevated temperature environments compared to standard nylon variants.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 306 series, which focuses on standard card edge solutions. The series offers various position counts and pitch options. The 306-018 variant specifically addresses mid-range density needs. It complements other EDAC products like the 302 series for finer pitches or the 316 series for different mechanical configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 306-018-421-102 and 306-018-421-112. These parts share the 18-position count and 0.156 inch pitch but may differ in housing color or specific flange features. Cross-series replacement requires verifying pitch and board thickness compatibility.
