306-027-521-108

Overview

The EDAC Inc. part number 306-027-521-108 is a standard card edge connector designed for dual-edge PCB mounting. It features 54 positions with female contacts arranged in a single centerline row. The contact spacing is 0.156 inches (3.96mm), and the connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The contacts are made of copper alloy with a gold finish, specifically 10.0µin (0.25µm) thick, utilizing a cantilever contact type. Termination is achieved via soldering, and the insulator body is green.

Feature Summary

• Dual-edge female connector configuration with cantilever contact type
• Gold-plated copper alloy contacts for reliable signal transmission
• Low profile insulator body design compatible with standard board thicknesses

Applications

• General purpose electronic assemblies requiring card edge interconnects
• Industrial control systems utilizing standard PCB modules
• Communication equipment backplanes or daughter cards

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required termination style and contact finish specifications. Confirm that the board thickness matches the 0.062-inch nominal requirement for proper mechanical engagement. Cross-reference the pin count and spacing parameters with the system design documentation before finalizing procurement orders to avoid integration errors.

Selection Notes

Select this component when a dual-edge female connector with 54 positions and 0.156-inch spacing is required. Ensure the application environment does not exceed the thermal ratings specified in the official datasheet. Consider the low-profile body height if vertical clearance within the enclosure is limited. Verify that the solder termination method aligns with the available assembly processes.

Part Context

This connector belongs to the EDAC standard card edge connector series, which provides reliable interconnection solutions for various electronic applications. The 306 series typically offers robust mechanical stability and electrical performance suitable for general industrial and commercial use cases where standard board thicknesses are utilized.

Replacement Considerations

Consult the official EDAC substitution guide or distributor cross-reference tools for verified equivalent part numbers. Do not assume functional interchangeability based solely on similar physical dimensions without confirming electrical and mechanical parameter alignment.
