306-026-420-178

Overview

The EDAC Inc. part number 306-026-420-178 is a standard card edge connector receptacle designed for through-hole mounting. It features a dual female configuration with 52 positions arranged in two rows. The contact spacing is 0.156 inches (3.96 mm), and the row spacing is 0.200 inches (5.08 mm). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. It is rated for a current of 5 A and includes an insulation resistance of 5 GOhms. The housing is constructed from thermoplastic polyester, providing structural integrity for industrial applications.

Feature Summary

• Dual female card edge receptacle design for secure board insertion
• Gold-plated copper alloy contacts for corrosion resistance and conductivity
• Through-hole termination method for robust PCB attachment
• Thermoplastic polyester housing material for durability

Applications

• Industrial control systems requiring high-density interconnects
• Computing and storage equipment backplanes
• Medical device circuit boards
• Communications network infrastructure modules

Procurement Notes

Verify the specific pin count and row configuration against the target PCB footprint before ordering. Confirm that the required current rating of 5 A aligns with the system's electrical load requirements. Ensure the through-hole mounting style matches the assembly process capabilities. Check for any RoHS compliance documentation if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when a dual-row card edge interface with 0.156-inch spacing is required. The 52-position layout suits applications needing moderate I/O density. Consider the 5 A current rating for power or signal lines. The through-hole option offers mechanical stability compared to surface mount alternatives. Verify compatibility with the mating card edge thickness and guide rail constraints.

Part Context

This connector belongs to the EDAC 306 series, which focuses on standard card edge solutions. EDAC has been a leader in interconnect technology since 1966, serving sectors like aerospace, medical, and industrial markets. The 306 series provides reliable connections for computing and storage applications, emphasizing quality assurance and global distribution support for OEMs.

Replacement Considerations

Direct substitutes may include other EDAC 306 series variants with matching position counts and spacing. Cross-reference specifications for identical 0.156-inch pitch and 52-pin dual-row configurations. Ensure replacement parts maintain the same through-hole mounting style and gold plating finish for equivalent performance.
