Overview

The EDAC Inc. 306-027-500-178 is a standard card edge connector receptacle from the 306 series, designed for through-hole mounting with a straight orientation. It features 54 positions arranged in a dual configuration with a 0.156-inch (3.96 mm) pitch. The contacts are constructed from copper alloy and gold-plated to ensure reliable signal transmission. The unit accommodates board thicknesses between 0.054 and 0.070 inches and utilizes thermoplastic polyester insulation.

Feature Summary

Dual-edge female contact design for secure board insertion
Gold-plated copper alloy contacts for corrosion resistance
Through-hole solder termination for robust PCB attachment

Applications

High-density electronic module interconnection
Industrial control system backplanes
Telecommunications equipment interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, plating thickness, and flange characteristics. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status as required by project regulations.

Selection Notes

Select this component when a high-pin-count dual-edge interface is required for rigid PCBs. Evaluate the 3.96 mm pitch against available routing space. Consider the through-hole mounting style for mechanical stability in vibration-prone environments compared to surface-mount alternatives.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and mounting options. The 306-027 variant specifically provides a 54-position dual configuration suitable for applications requiring substantial I/O density within a single connector footprint.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with differing pin counts or flange styles. Verify that alternative parts match the 0.156 inch pitch and dual-edge geometry to maintain mechanical and electrical compatibility.
