305-080-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-080-521-508 is a standard card edge connector from the 305 series, designed for dual-row female connections. It features 80 positions with a 3.96 mm (0.156 inch) pitch and supports non-specified dual-edge cards. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. It is rated for 5 A current and operates within a temperature range of -40°C to +105°C. The unit employs solder pin termination and is intended for panel mount installation.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 80 contact positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic polyester insulation offers durability and stable performance across wide temperature ranges
• Solder pin termination facilitates secure panel mounting and mechanical stability

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board connections
• Medical devices needing reliable high-pin-count connectors
• Consumer electronics manufacturing with specific form factor requirements

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffixes against official EDAC documentation to ensure correct housing color, plating thickness, and mounting style specifications. Confirm that the target application matches the dual-edge card requirement and panel mount orientation. Check RoHS compliance status directly with the manufacturer or authorized distributors as regulatory requirements may vary by production batch. Ensure compatibility with the specified PCB thickness and operating temperature range before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 80-position interface is required with a 3.96 mm pitch. The 305 series provides versatile mounting options suitable for panel installations. Consider the gold plating for enhanced conductivity and the thermoplastic housing for environmental resilience. Verify that the 5 A current rating and -40°C to +105°C operating range meet the system's electrical and thermal demands. Ensure the dual-edge card specification aligns with the mating board design.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers a broad range of card edge solutions with varying position counts and mounting styles. The series is characterized by its 3.96 mm pitch and robust construction using copper alloy contacts. EDAC designs these components for reliability in demanding environments, supporting both single and dual-row configurations. The 305 series is widely used in industrial and commercial applications requiring secure, high-density interconnections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include models with identical 80-position counts and 3.96 mm pitch, such as 305-080-521-201 or 305-080-555-568, provided the housing color and specific flange features match the design. Cross-series replacements require careful verification of pitch, row count, and mounting dimensions to ensure mechanical and electrical compatibility without redesigning the PCB footprint.
