305-044-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-044-500-204 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 44 positions arranged in two rows, providing a total of 22 contacts per row. The connector utilizes a 0.156-inch (3.96 mm) pitch and accepts board thicknesses within the range of 0.054 to 0.070 inches (1.37 mm to 1.78 mm). It employs solder eyelet termination and gold-plated copper alloy contacts. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density signal routing
• Solder eyelet termination ensures secure PCB attachment
• Gold-plated copper alloy contacts provide reliable conductivity
• Vertical panel mount design with flanged installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position dual-row configuration and 3.96 mm pitch. Confirm that the solder eyelet termination style aligns with the target printed circuit board layout. Ensure the operating temperature range of -40°C to +105°C meets the environmental requirements of the intended application. Check RoHS compliance status if restricted substances are a concern.

Edgeboard Connectors Selection Notes

Select this component when a robust, vertically mounted card edge interface is required for industrial or commercial applications. The dual-row arrangement supports higher pin counts compared to single-row alternatives. The solder eyelet termination is suitable for through-hole assembly processes. Consider the 0.156-inch pitch as a standard spacing option for general-purpose connectivity needs.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles to accommodate different board designs. The 305-044-500-204 specifically addresses the need for a 44-contact interface with durable metal contacts and a thermoplastic housing. It serves as a critical link between daughterboards and main systems in modular architectures.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 44-position, dual-row, and 3.96 mm pitch specifications. Verify compatibility with existing panel cutouts and board thickness constraints before swapping components.
