306-027-521-104

Overview

The EDAC Inc. 306-027-521-104 is a dual-edge female card edge connector from the 306 series, designed for vertical board-to-board connections. It features 54 positions with a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The contacts are gold-plated copper alloy terminals housed in a green insulator body. Rated for an operating temperature range of -40°C to +105°C, this component utilizes a low-profile design suitable for space-constrained applications requiring reliable signal transmission.

Feature Summary

• Dual-edge female configuration for secure vertical insertion
• Gold-plated contacts ensure corrosion resistance and stable conductivity
• Low-profile insulator body optimizes spatial efficiency
• Accepts standard 0.062-inch nominal thickness PCBs

Applications

• Industrial control systems
• Telecommunications equipment
• Consumer electronics modules
• Medical device interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pin count, plating type, and orientation. Ensure compatibility with the target PCB stack-up and mating connector specifications. Cross-reference the part number with official distributor catalogs to confirm availability and lead times prior to procurement.

Selection Notes

Select this component when a dual-edge female connection is required for standard thickness boards. Consider the 0.156-inch pitch and low-profile housing dimensions for mechanical fit. Evaluate the thermal rating and material composition against environmental conditions. Confirm that the 54-position capacity meets the circuit density requirements.

Part Context

This connector belongs to the EDAC 306 series, which specializes in card edge solutions for various industries. The series offers multiple configurations including single and dual edges with varying pin counts. EDAC designs these components to provide robust connectivity in demanding environments, supporting both through-hole and surface-mount mounting styles across different product lines.

Replacement Considerations

Compatible substitutes include other EDAC 306 series connectors with matching 54-position dual-edge female configurations. Verify identical 0.156-inch pitch and 0.062-inch board thickness acceptance. Ensure equivalent gold plating and operating temperature ranges before substitution.
