305-050-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-503 is a standard card edge connector from the 305 Series, designed for dual-edge PCB interfaces. It features 50 positions with a 3.96 mm (0.156 inch) pitch and a two-row configuration. The contacts are gold-plated copper alloy, rated for 5 A continuous current and 1800 VACrms insulation voltage. The housing is green thermoplastic, supporting panel mounting in a vertical orientation. It accommodates board thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific suffix '503' against official EDAC documentation to confirm the exact plating thickness, housing color, and keying options. Ensure compatibility with the target PCB's dual-edge profile and required polarizing key configurations before procurement.

Edgeboard Connectors Selection Notes

Select this component when a high-current 5 A rating and robust 1800 VACrms insulation are required for vertical panel-mounted applications. The 3.96 mm pitch suits larger form-factor cards, while the dual-row layout maximizes signal density within the specified footprint constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting styles. The series is characterized by its durable thermoplastic construction and standardized 3.96 mm pitch, providing a versatile solution for heavy-duty card edge connections in demanding environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-038-520-502 or 305-062-555-503 if position count adjustments are necessary. Verify that alternative parts maintain the same 3.96 mm pitch and dual-row configuration to ensure mechanical fit.
