305-084-555-558

Edgeboard Connectors Overview

The EDAC Inc. 305-084-555-558 is a standard card edge connector from the 305 series, designed for panel mounting with a vertical orientation. It features 84 positions arranged in two rows with a contact pitch of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Contacts are made of copper alloy and gold-plated, supporting a continuous current rating of 5 A. The insulator body is green thermoplastic polyester, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Panel mount straddle design with integrated card guide features
• Gold-plated copper alloy contacts for reliable signal transmission
• Compatible with between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board formats
• Test and measurement devices needing high-density connections
• Military and aerospace applications adhering to MIL-C-21097 standards

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness, insulation color, and flange specifications. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the panel cutout dimensions align with the straddle-mount footprint. Check for RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 84-position interface is required for vertical panel integration. The 3.96 mm pitch suits applications where board density is moderate but mechanical stability is critical. Consider the 5 A current rating for power distribution needs. Verify that the green thermoplastic housing meets environmental requirements for the intended operating temperature range.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are widely used in modular electronic systems. The series offers various position counts and mounting styles. The 305-084 variant specifically provides a high-pin-count solution for complex circuit boards. It is often compared with similar parts like the 305-080 or 305-084-555-568, differing mainly in flange details or packaging.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC part numbers within the same 305 series with identical pin counts and pitch, such as 305-084-555-568, provided flange configurations match. Cross-brand replacements require verifying mechanical dimensions, electrical ratings, and material compatibility. Always consult the latest datasheet for dimensional tolerances before substitution.
