305-044-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-044-555-503 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 44 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. Rated for 5 A current at +105°C maximum operating temperature, it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). This vertical panel-mount header provides reliable interconnection in industrial environments.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for non-specified dual-edge card insertion
• Gold-plated copper alloy contacts ensure durable electrical performance
• Vertical panel mount style with low-profile insulator body design

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating thickness and insulation color specifications. Ensure the host PCB accommodates the required 1.57 mm thickness tolerance. Confirm that the mounting hole pattern aligns with the panel installation requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 44 positions is required. The 3.96 mm pitch suits applications needing robust mechanical stability. Verify that the 5 A current rating meets the signal load requirements. Consider the vertical orientation for space-constrained panel layouts. Ensure compatibility with the target PCB manufacturing tolerances for optimal contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its standardized 3.96 mm pitch and durable construction. Components in this family are engineered for high-reliability connections in demanding operational environments. The 305-044 variant specifically addresses needs for higher density dual-edge connectivity within the same structural footprint constraints.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series connectors with matching 44-position counts and identical 3.96 mm pitch. Verify that alternative parts maintain the same dual-edge female configuration and vertical panel mount style. Ensure replacement components support the same PCB thickness and current ratings.
