306-034-521-101

Overview

The EDAC Inc. 306-034-521-101 is a dual-edge female card edge connector featuring 68 positions with a 0.156-inch (3.96mm) contact spacing. It utilizes cantilever contacts with gold plating and accepts printed circuit boards ranging from 0.054 to 0.070 inches in thickness. The unit employs a thermoplastic polyester insulator, operates between -40°C and 105°C, and supports through-hole termination.

Feature Summary

• Dual-edge female configuration with cantilever contact design for reliable board insertion
• Gold-plated contacts ensure stable electrical performance over repeated mating cycles
• Thermoplastic polyester insulation provides structural integrity within specified temperature ranges

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics module connections

Procurement Notes

Verify the complete part number against manufacturer documentation to confirm specific flange dimensions and contact finish thickness. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status matches project requirements. Cross-reference lead times with current supply chain data as availability may fluctuate based on manufacturing schedules.

Selection Notes

Select this component when a dual-edge interface with 0.156-inch spacing is required. Verify that the target PCB thickness falls within the accepted range of 0.054 to 0.070 inches. Consider the operating temperature range and termination method during mechanical design integration. Ensure sufficient clearance for the connector height and flange features.

Part Context

This connector belongs to the EDAC 306 series of standard card edge connectors. The series offers various position counts and configurations designed for general-purpose electronic applications. The 306 series emphasizes durability and consistent electrical performance across industrial and commercial environments.

Replacement Considerations

Direct substitutes require matching 68-position dual-edge female specifications with identical 0.156-inch spacing. Verify PCB thickness compatibility and termination style alignment. Flange dimensions must match existing mounting constraints. Contact material and plating thickness should meet or exceed original requirements.
