305-016-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-016-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 16 positions with a 3.96 mm (0.156 inch) pitch and supports a PCB thickness range of 1.37 mm to 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin (0.25 µm) plating thickness and half-beam contact type. Rated for 5 A current, it employs a thermoplastic polyester insulator and solder pin termination. Operating temperatures span from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration with half-beam contacts for secure mating
• Gold-plated copper alloy terminals ensure reliable conductivity
• Thermoplastic polyester housing provides thermal stability
• Panel mount design with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact mechanical dimensions and plating specifications. Ensure compatibility with the target PCB thickness within the specified tolerance range. Confirm RoHS compliance status through the latest datasheet revision before integration into regulated environments.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required with a 3.96 mm pitch. The vertical panel mount style suits chassis-based architectures. Consider the 5 A rating and temperature range for environmental suitability. Verify that the half-beam contact type aligns with the mating card's insertion force requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and mounting styles. The 305-016 variant specifically addresses 16-position needs. It is distinct from single-row or different pitch alternatives in the broader catalog.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical pitch and position count but different mounting styles, such as 305-016-556-504. Cross-brand replacements require matching the 3.96 mm pitch, 16-position layout, and dual-edge acceptance criteria.
