305-052-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-052-555-203 is a standard card edge connector from the 305 Series, designed for dual female contact configurations with 52 positions. It features a 0.156-inch (3.96 mm) contact spacing and a 0.140-inch (3.56 mm) row spacing. The connector 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 solder lug termination type for secure panel mounting. The insulator body is made of green thermoplastic polyester, providing a low-profile design suitable for vertical installation in electronic assemblies.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with 52 positions for high-density board connections
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Low-profile insulator body constructed from green thermoplastic polyester
• Solder lug termination supports secure vertical panel mounting applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard PCB form factors
• Test and measurement instrumentation panels
• General-purpose electronic assemblies needing dual-row connectivity

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm exact physical dimensions and termination style, as variations exist within the 305 series. Confirm that the target application requires a dual female connector rather than a single or mixed polarity variant. Ensure compatibility with the specified 0.062-inch nominal PCB thickness to guarantee proper mechanical engagement. Check regional availability constraints, as distribution status may vary by location.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 52 positions is required for vertical panel mounting. The 3.96 mm pitch accommodates standard board layouts while the 3.56 mm row spacing provides adequate isolation. Verify that the operating temperature range of -40°C to +105°C meets environmental requirements. Consider the gold plating thickness if long-term reliability in harsh conditions is critical compared to tin alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors, which offers various position counts and mounting options. The series is characterized by its consistent 3.96 mm contact spacing and robust construction using copper alloy contacts. These connectors are widely used in industrial and commercial electronics where reliable, high-density interconnections between backplanes and daughter cards are necessary.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 52-position dual female configurations. Verify that alternative parts maintain the same 0.156-inch pitch and 0.140-inch row spacing for direct mechanical interchangeability. Ensure the replacement also supports the 0.062-inch board thickness and utilizes gold-plated contacts for equivalent electrical performance.
