305-058-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-058-555-203 is a standard card edge connector from the 305 Series, designed for dual female board-to-board applications. It features 58 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The unit accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating, it utilizes a green thermoplastic polyester insulator body. The connector supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design suitable for space-constrained panel installations
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board formats
• Test and measurement instrumentation panels

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, termination style, and mounting configuration. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the required polarizing key type matches the application's mechanical constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 3.96 mm pitch is required for 1.57 mm thick boards. Consider the 5 A current rating and 1800 VACrms insulation capability for electrical safety margins. Evaluate the low-profile housing dimensions against available panel clearance to ensure proper fitment within the assembly enclosure.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent 0.156-inch spacing. These connectors are widely used in modular electronic designs where reliable, high-density interconnections are necessary for system expansion or replacement.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series variants with matching 58-position configurations and identical 3.96 mm pitch specifications. Verify that alternative parts support the same 0.062-inch board thickness and dual female contact arrangement to maintain mechanical and electrical interchangeability.
