305-084-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-501 is a dual-edge female card edge connector designed for through-hole mounting. It features 84 positions with a contact spacing of 0.156 inches (3.96mm) and a row spacing of 0.140 inches (3.56mm). The connector utilizes gold-plated contacts with a thickness of 10.0µin (0.25µm) on copper alloy terminals, housed in a green thermoplastic polyester insulator. It supports printed circuit boards with a nominal thickness of 0.062 inches (1.57mm) and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates non-specified double-sided PCBs
• Gold-plated semi-corrugated contacts ensure reliable electrical connection
• Low-profile insulator body design minimizes vertical space requirements

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment board connections
• Automotive electronics modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to confirm compatibility with required PCB thicknesses and termination styles. Ensure that the selected variant matches the necessary flange characteristics and insulation material specifications for the target application environment. Cross-reference the part number with current RoHS compliance documentation to meet regulatory standards.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge interface is required for standard thickness boards. The 0.156-inch spacing allows for broader trace routing compared to finer pitches. Consider the through-hole termination method for applications demanding mechanical stability during soldering. Evaluate the operating temperature range against environmental conditions to ensure long-term reliability.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors, which are engineered for general-purpose electronic interconnections. The series offers various pin counts and spacing options to suit different board densities. The 305-084 model specifically addresses applications needing substantial I/O capacity within a compact footprint, utilizing durable materials for repeated insertion cycles.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing pin counts or spacing. Verify mechanical dimensions and terminal configurations before replacing with generic equivalents to ensure PCB layout compatibility.
