306-009-521-178

Edgeboard Connectors Overview

The EDAC Inc. 306-009-521-178 is a standard card edge connector designed for dual-edge PCB insertion. It features 18 positions with a 0.156-inch (3.96mm) contact spacing arranged in a single centerline row. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contacts are gold-plated to ensure reliable signal transmission and corrosion resistance. The unit utilizes a low-profile insulator body finished in green, providing a compact form factor suitable for space-constrained electronic assemblies.

Edgeboard Connectors Feature Summary

• Dual-edge design accommodates standard card edge PCBs
• Gold-plated contacts provide durable electrical connectivity
• Low-profile insulator body reduces overall assembly height

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment modules
• Consumer electronics board-to-board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact pin count and plating specifications. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Cross-reference the component revision history to confirm material consistency. Confirm that the single-row configuration matches the design layout requirements.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge connector is required for 18-position applications. The 0.156-inch pitch is standard for many legacy and industrial interfaces. Verify that the PCB stack-up allows for the specified 0.062-inch thickness. Consider the green insulator color for visual identification during assembly processes.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, which specializes in card edge connectors with 0.156-inch spacing. The series offers various position counts and mounting styles. The 306-009-521-178 specifically addresses needs for moderate density connections with a focus on low profile and reliable gold contact performance.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 18-position count, 0.156-inch pitch, and dual-edge configuration. Verify that alternative components support the same 0.062-inch PCB thickness. Check for identical mounting style and contact plating requirements to ensure functional interchangeability.
