305-042-556-503

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-503 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin thickness, housed in a green thermoplastic polyester insulator. Rated for 5 A current, it supports vertical panel mounting via solder lug termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific flange dimensions and plating thickness. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure panel cutout dimensions align with the specified flange diameter and opening size for proper installation.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and operating temperature range for environmental suitability. Verify that the target PCB thickness falls within the 1.37 mm to 1.78 mm acceptance window for optimal contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are characterized by their robust construction and versatile mounting options. The series offers various position counts and pitch configurations to accommodate diverse electronic assembly needs while maintaining consistent electrical performance standards across the product line.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-042-520-202 for identical pin counts and pitch but potentially different flange or termination details. Verify mechanical compatibility before substitution to ensure panel fit and electrical continuity remain unaffected.
