306-028-420-101

Overview

The EDAC Inc. 306-028-420-101 is a standard card edge connector receptacle from the 306 series. It features 56 positions with a 3.96 mm (0.156 inch) pitch and supports dual-edge mating. Designed for vertical panel mount installation, it accommodates a board thickness of 1.57 mm. The contacts are gold-plated copper alloy, while the housing is constructed from green thermoplastic polyester. Rated for 5 A current, it utilizes solder pin termination.

Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Vertical panel mount orientation with integrated mounting stability
• Gold-plated copper alloy contacts ensuring reliable signal transmission
• Thermoplastic polyester housing providing thermal resistance

Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device circuit board interfaces
• Energy management hardware connections

Procurement Notes

Verify the specific suffix code to confirm plating type and housing color variations within the 306 series. Confirm that the target application requires the 3.96 mm pitch specification. Ensure compatibility with the intended PCB thickness of 1.57 mm before finalizing the order. Check regional availability as distribution may be restricted in certain areas.

Selection Notes

Select this component when a high-density 56-position interface is required with a 3.96 mm spacing. Choose the gold-plated variant for applications demanding superior corrosion resistance and conductivity. Consider the vertical panel mount style if space constraints require a perpendicular connection relative to the chassis. Verify that the 5 A current rating meets the electrical load requirements of the design.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and pitch options to suit different density requirements. EDAC manufactures these components using durable materials suitable for rigorous industrial environments, ensuring long-term reliability in critical electronic assemblies.

Replacement Considerations

Direct substitutes include other 306 series variants such as 306-028-420-103 or 306-028-421-101, provided the pin count and pitch match exactly. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to ensure functional equivalence.
