306-021-521-104

Overview

The EDAC Inc. 306-021-521-104 is a single-row card edge connector designed for through-hole mounting. It features 42 positions with a 0.156-inch (3.96mm) contact spacing and accepts PCBs with a nominal thickness of 0.062 inches (1.57mm). The connector utilizes copper alloy contacts with a gold finish, ensuring reliable electrical performance. It is rated for operation between -65°C and 125°C and includes a flange for secure panel installation.

Feature Summary

• Single centerline row configuration with 0.156 inch contact spacing
• Low profile insulator body construction
• Gold-plated copper alloy contacts for durability
• Panel mount design with integrated flange

Applications

• Industrial control systems requiring robust interconnects
• Communication equipment board-to-panel connections
• Test and measurement instrumentation interfaces
• Automotive electronics modules

Procurement Notes

Verify the specific part number suffix to confirm contact configuration and plating specifications. Ensure compatibility with the target PCB thickness range of 0.062 inches. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer's ordering guide for accurate lead times and packaging details before finalizing procurement orders.

Selection Notes

Select this component when a single-row, high-density connection is required for thicker PCBs. The 0.156-inch spacing provides mechanical stability compared to finer pitches. Consider the through-hole termination method for superior mechanical strength in vibration-prone environments. Evaluate the operating temperature range against environmental conditions.

Part Context

This connector belongs to the EDAC 306 series of edgeboard connectors. It is engineered for applications demanding high reliability and durable connections. The series offers various pin counts and configurations to suit different board sizes. It serves as a critical interface component in modular electronic systems.

Replacement Considerations

Direct substitutes within the same series include parts with identical spacing and pin count but different termination styles. Verify that alternative models maintain the same PCB thickness tolerance and flange dimensions to ensure mechanical fit without modification.
