305-074-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-074-500-204 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 74 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 5 A current rating and 1800 VACrms insulation capability. It employs a panel mount vertical installation style with solder lug termination. The housing is constructed from thermoplastic polyester, offering an operating temperature range of -40°C to +105°C and an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with required polarizing key types before procurement. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to guarantee proper mechanical engagement and electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5 A rating and 1800 VACrms dielectric strength are required for vertical panel mounting. The 3.96 mm pitch accommodates standard dual-edge cards. Consider the 305 series characteristics for applications needing polarizing key support and thermoplastic insulation durability across wide temperature ranges.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides standard card edge connectors for various industrial and commercial applications. The series is characterized by its ability to accept polarizing keys and its robust construction using thermoplastic materials. These connectors are engineered for reliability in environments demanding stable electrical connections over extended operational periods.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching pin counts and pitch, such as the 305-074-500-201 or 305-074-500-204 equivalents. Verify that any replacement maintains the same 3.96 mm pitch, 74-position count, and panel mount orientation to ensure mechanical fit.
