305-022-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-022-500-203 is a standard card edge connector from the 305 series, designed for dual female interface applications. It features 22 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The unit utilizes copper alloy terminals with gold plating and accepts board thicknesses ranging from 1.37 mm to 1.78 mm. Rated for 5 A continuous current and 1800 VACrms insulation, it operates within a temperature range of -40°C to +105°C. The insulator is made of green thermoplastic polyester, providing high insulation resistance.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify that the specific order matches the 305-022-500-203 designation, as the 305 series includes various pin counts and mounting styles. Confirm compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm prior to integration. Ensure environmental conditions remain within the specified -40°C to +105°C operating window. Check for RoHS compliance requirements if applicable to the final assembly standards.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 3.96 mm pitch is required for vertical or panel mounting configurations. The 5 A current rating suits moderate power signal transmission needs. Consider the flush mount flange feature for secure panel installation. Verify that the gold plating thickness meets corrosion resistance requirements for the intended operational environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability and precise alignment. The series accommodates various position counts while maintaining consistent pitch and material specifications. The 305-022-500-203 variant specifically addresses applications requiring 22 contacts with dual-sided access.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 22-position count, 3.96 mm pitch, and dual female terminal type. Verify identical flange dimensions and mounting style compatibility. Cross-reference insulation material and temperature ratings to ensure equivalent performance in existing designs.
