305-044-520-508

Edgeboard Connectors Overview

The EDAC Inc. 305-044-520-508 is a dual-edge female card edge connector designed for panel and through-hole mounting. It features 44 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). It accommodates board thicknesses from 0.054 to 0.070 inches (1.37mm to 1.78mm). The insulator is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to confirm mechanical and electrical specifications match the application requirements. Ensure compatibility with the target PCB thickness and mounting constraints before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability and lead times.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required for panel-mounted applications. Consider the 44-position count and 2-row layout for circuit density needs. Verify that the operating temperature range of -40°C to +105°C meets environmental conditions. Confirm that the board thickness falls within the 0.054 to 0.070-inch specification for proper contact engagement.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options for diverse electronic interconnection needs. The 305-044 variant specifically provides a mid-range contact count suitable for moderate-density circuit boards. It utilizes standard industrial materials and finishes for durability.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or mounting styles. Verify cross-compatibility with other manufacturers' dual-edge connectors by matching pitch, row count, and board thickness specifications.
