305-078-520-503

Edgeboard Connectors Overview

The EDAC 305-078-520-503 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 78 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and supports printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts and gold plating, it ensures stable electrical performance. The thermoplastic insulator body provides durability, while the solder pin termination method facilitates secure mounting.

Edgeboard Connectors Feature Summary

• Dual female card edge interface accommodating 78 positions for high-density connections
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Compatible with 1.57 mm nominal thickness PCBs for standardized board integration

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify part authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status via official documentation before procurement. Ensure storage conditions maintain component integrity. Cross-reference ordering suffixes to match specific mechanical requirements. Request manufacturer certificates of conformity for quality assurance purposes.

Edgeboard Connectors Selection Notes

Select this model when a 78-position dual-row connection is required for 1.57 mm thick boards. Verify that the 3.96 mm pitch aligns with the target PCB layout. Consider the vertical panel mount style if space constraints dictate external housing integration. Evaluate the 5A current rating against system power demands to ensure adequate capacity.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts to suit different density needs. These connectors are engineered for robust performance in demanding environments. The design emphasizes mechanical stability and electrical reliability for long-term operational use.

Edgeboard Connectors Replacement Considerations

Consult EDAC technical documentation for direct cross-references. Verify identical pitch, row count, and board thickness compatibility. Ensure mating dimensions match existing assembly constraints before substitution.
