305-066-556-202

Edgeboard Connectors Overview

The EDAC Inc. 305-066-556-202 is a dual-edge female card edge connector designed for board-to-board applications. It features 66 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The contacts are made of copper alloy with a gold plating thickness of 10.0µin (0.25µm). The insulator is green thermoplastic polyester, rated for operation between -40°C and +105°C. It supports card thicknesses from 0.054 to 0.070 inches and utilizes a half-beadlock contact type for secure mating.

Edgeboard Connectors Feature Summary

• Dual-row female configuration for high-density signal routing
• Gold-plated half-beadlock contacts ensure reliable electrical connection
• Thermoplastic polyester insulator provides thermal stability
• Flanged design facilitates flush mounting on adapter boards

Edgeboard Connectors Applications

• Adapter board interconnects
• High-density circuit board connections
• Industrial control system backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm compatibility with required flange styles and termination methods. Ensure that the procurement documentation explicitly references the RoHS3 compliance status and the exact pin count to avoid substitution errors during assembly integration.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 0.156-inch pitch is required for non-specified card types. Confirm that the target PCB thickness falls within the 0.054 to 0.070-inch range to ensure proper mechanical engagement and electrical performance without excessive stress on the contacts.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of edgeboard connectors. The series is characterized by its robust construction and suitability for adapter board applications. The 305 series offers various position counts while maintaining consistent pitch and mounting characteristics across the product line.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row configuration but different pin counts, such as 305-050-556-202 or 305-020-556-202. Verify mechanical footprint compatibility before substituting.
