305-082-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-082-520-278 is a standard card edge connector featuring an 82-position dual-row configuration with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. Designed for panel mounting, it accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch), accommodating a range from 0.054 to 0.070 inches. The connector utilizes copper alloy contacts with gold plating and a thermoplastic insulator body. It supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count, termination type, and insulation material properties. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the dual-row configuration matches the system's mechanical constraints. Cross-reference ordering numbers with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust mechanical retention for thick PCBs. Consider the 5 A current rating for power distribution needs alongside signal lines. Evaluate the operating temperature range against environmental conditions. Ensure the dual-edge design aligns with the mating card's edge geometry requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various position counts and mounting options. The series is characterized by its standardized 3.96 mm pitch and durable construction. Similar models in the series vary primarily by position count and specific termination styles, maintaining consistent electrical performance and mechanical dimensions across the lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 82-position count, 3.96 mm pitch, and dual-row configuration. Verify that alternative connectors support the same PCB thickness range and panel mounting style. Ensure equivalent current ratings and temperature specifications are met. Check for compatible contact plating materials to maintain corrosion resistance.
