305-084-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-504 is a standard card edge connector header from the 305 series, designed for panel mount installation with a vertical orientation. It features 84 positions arranged in a dual-row configuration with a 3.96 mm (0.156 inch) pitch. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. Rated for 5 A continuous current, this component utilizes solder lug termination for secure board attachment. It accommodates PCB thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact design accepting non-specified double-sided card edges
• Gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Panel mount vertical installation style with solder lug termination
• Compatible with between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control system backplanes
• High-density electronic module interconnects
• Telecommunications equipment signal routing
• Automotive electronics interface boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm exact pin count, termination type, and flange characteristics. Ensure compatibility with target PCB thickness and polarizing key requirements before procurement. Cross-reference the Mouser or DigiKey part number for accurate availability status, as distribution channels may vary by region.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count, dual-row connection is required for vertical panel mounting. The 3.96 mm pitch supports dense circuit layouts while maintaining robust mechanical stability. Verify that the application environment falls within the specified -40°C to +105°C operating range and that the 5 A current rating meets the electrical load requirements of the connected modules.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination options to suit different density and mechanical constraints. The 305-084 variant specifically addresses applications requiring extensive I/O connections in a compact vertical form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and row configuration but differing pin counts, such as 305-072-555-504 or 305-096-555-504. Ensure any replacement maintains the 3.96 mm pitch and vertical panel mount style to preserve mechanical fit.
