305-080-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-080-555-258 is a standard card edge connector from the 305 series, designed for dual female contact configurations with 80 total positions arranged in two rows of 40. It features a 3.96 mm (0.156 inch) pitch and utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) thickness. The component supports panel mounting via flush-mount flanges with top openings and threaded inserts compatible with 4-40 screws. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and accommodates board thicknesses between 1.37 mm and 1.78 mm.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density signal routing
• Flush-mount installation with threaded insert flange features
• Gold-plated copper alloy contacts ensuring reliable conductivity

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct flange and termination specifications. Confirm that the required board thickness falls within the specified 1.37 mm to 1.78 mm range. Check RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 80-position interface with a 3.96 mm pitch is required. Ensure the application demands flush-panel mounting with threaded hardware rather than snap-in or surface-mount options. Verify that the operating environment stays within the -40°C to +105°C range and that the PCB thickness matches the connector's acceptance window.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of card edge connectors, which offer various mounting styles and position counts. The series is characterized by thermoplastic polyester insulation and standardized 3.96 mm spacing, providing a robust solution for vertical panel-mounted applications requiring durable electrical connections.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the same 305 series family, such as 305-080-555-568, for alternative flange configurations. Verify mechanical compatibility and electrical ratings before substituting any similar EDAC components.
