306-027-500-103

Overview

The EDAC Inc. 306-027-500-103 is a dual-edge female card edge connector from the 306 series, designed for panel mounting with solder lug termination. It features 54 positions arranged in a double row with a 0.156-inch (3.96mm) spacing. The contacts are made of copper alloy with gold plating and utilize a cantilever design. The housing is green thermoplastic polyester, rated for -40°C to 105°C. It supports board thicknesses of 0.054 to 0.070 inches and includes flush mount flanges with a 0.116-inch diameter.

Feature Summary

• Dual-edge female contact configuration for non-specified card types
• Cantilever spring contact design for reliable signal transmission
• Gold-plated copper alloy terminals ensuring corrosion resistance
• Flush mount flange feature with floating bobbin capability

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Procurement Notes

Verify that the specific part number matches the required pin count and spacing specifications before ordering. Confirm compliance with RoHS3 standards if environmental regulations apply to your project. Ensure the receiving facility has appropriate handling procedures for surface-mount or through-hole soldering processes as indicated by the lug termination type.

Selection Notes

Select this component when a robust dual-edge interface is required for high-density applications. The 0.156-inch pitch accommodates standard board layouts while the gold plating ensures long-term conductivity. Consider the operating temperature range and mechanical durability requirements to ensure compatibility with the target environment and mating card specifications.

Part Context

This connector belongs to the EDAC 306 series, which provides versatile solutions for edgeboard connections. The series is known for its durable construction and reliable performance in demanding environments. The 306-027 variant specifically addresses higher pin count needs within the standard spacing format, offering a balance between density and mechanical stability.

Replacement Considerations

Compatible substitutes include the 306-027-500-104 and 306-027-520-103 models from the same manufacturer. These alternatives share similar electrical characteristics and form factors but may differ in packaging or minor mechanical details. Verify cross-compatibility with existing tooling and board designs before switching.
