305-050-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-258 is a standard card edge connector from the 305 series, designed for dual-edge board connections. It features 50 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance. The unit utilizes a green thermoplastic polyester insulator body and employs solder pin termination for secure panel mounting.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB thickness of 0.062 inches before procurement. Confirm RoHS compliance status through current manufacturer declarations as regulatory requirements may evolve. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 50-position interface with a 3.96 mm pitch. The 305 series offers a low-profile solution suitable for applications where vertical space is constrained. Verify that the mating card thickness aligns with the specified 1.57 mm nominal dimension. Consider the gold plating requirement for environments demanding high corrosion resistance and stable contact impedance over extended operational cycles.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which provides various mounting options and row configurations. The series is characterized by its standardized dimensions and reliable performance in harsh environments. The 305-050-555-258 specifically addresses the need for a 50-position dual-row interface, fitting within the broader catalog of interconnect solutions offered by EDAC Inc. for industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching position counts and pitch, such as the 305-050-556-201, provided the mounting style and termination type are compatible. Verify mechanical fit and electrical ratings before substitution. Generic equivalents may lack the specific row spacing and insulator material properties defined in the original specification.
