305-070-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-070-556-208 is a dual-edge female card edge connector designed for board-to-board or panel mounting applications. It features 70 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated contacts and a green thermoplastic polyester insulator, supporting a card thickness range of 0.054 to 0.070 inches. Rated for operation between -40°C and +105°C, it offers reliable electrical performance for industrial environments.

• Thermoplastic polyester insulation provides durability
• Supports vertical panel or PCB mounting styles

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Panel-mounted electronic modules
• Communication equipment backplanes
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's current ordering guide to confirm exact flange and termination options. Ensure compatibility with the target card thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the DigiKey part number alias for accurate sourcing channels.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required for panel integration. The 0.156-inch pitch accommodates standard board layouts while the gold finish supports frequent mating cycles. Consider the vertical mounting style for space-constrained enclosures where direct board insertion is not feasible.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its versatility in mounting styles and contact configurations. The 305-070 variant specifically addresses higher pin count requirements within the family, maintaining consistent dimensional standards across the product line.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for verified substitutes. Alternative part numbers may vary in flange characteristics or termination methods. Do not assume interchangeability without verifying mechanical fit and electrical ratings.
