305-054-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-054-555-258 is a standard card edge connector header featuring 54 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and is designed for panel mounting with vertical orientation. The contacts are constructed from copper alloy with gold plating, supporting a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The unit accommodates board thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Provides high dielectric strength with 1800VACrms voltage rating
• Features thermoplastic insulator housing for thermal stability

Edgeboard Connectors Applications

• High-density electronic module interconnection
• Industrial control system backplanes
• Telecommunications equipment signal routing

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure compatibility with required polarizing key configurations and termination styles. Confirm that the 5A current rating aligns with the thermal management capabilities of the target application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a robust dual-row interface is required for thick PCB applications. The 3.96 mm pitch allows for wider trace spacing compared to finer pitches, reducing crosstalk risks in high-power scenarios while maintaining a compact footprint relative to total position count.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by heavy-duty construction suitable for demanding environments. The 305-054 variant specifically addresses the need for higher pin counts in dual-row formats without compromising mechanical integrity or electrical performance standards.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-054-556-278 and 305-054-520-258. Verify that alternative suffixes match the exact contact plating thickness and insulator material specifications to maintain equivalent environmental ratings.
