305-016-520-501

Edgeboard Connectors Overview

The EDAC Inc. 305-016-520-501 is a dual-row card edge connector designed for through-hole mounting. It features 16 positions with a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5A continuous current and 1800VACrms insulation, it operates within a temperature range of -40°C to +105°C. The insulator body is constructed from thermoplastic polyester, providing durability in demanding environments.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Low profile insulator body design for compact assembly requirements
• Gold-plated contacts provide corrosion resistance and stable electrical performance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics operating in high-vibration environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm mechanical variations such as mounting style or contact finish. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Edgeboard Connectors Selection Notes

Select this component when a dual-row configuration with 16 positions is required. The 0.156-inch pitch suits applications needing wider spacing for higher voltage isolation. Consider the 5A current rating for power distribution needs. Verify that the through-hole termination method aligns with the manufacturing process. Check for polarizing key compatibility if precise board insertion is critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations to support diverse interface needs. Components in this family share common design principles, including gold-plated contacts and thermoplastic insulators. The 305 series is widely used in general-purpose electronic assemblies requiring reliable board-to-board connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and pitch but different suffixes for minor mechanical variations. Verify that any replacement maintains the 0.156-inch spacing and 0.062-inch board thickness acceptance. Ensure the alternative part retains the 5A current rating and compatible termination style.
