306-031-421-103

Overview

The EDAC Inc. 306-031-421-103 is a dual-sided card edge connector designed for panel mount and through-hole termination. It features 62 positions with a 0.156-inch (3.96mm) spacing and a 0.200-inch (5.08mm) row pitch. The connector utilizes copper alloy contacts with gold plating, supporting board thicknesses of 0.054 to 0.070 inches. Operating within a temperature range of -40°C to 105°C, it employs a thermoplastic polyester insulator and offers a flange feature for secure installation.

Feature Summary

• Dual-sided female contact configuration for robust board-to-board connectivity
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Panel mount design with integrated flange for stable mechanical fixation
• Thermoplastic polyester insulation provides durability across specified thermal ranges

Applications

• Industrial control systems requiring durable interconnects
• Medical equipment interfaces demanding reliable signal integrity
• Agricultural technology hardware exposed to harsh environments
• Communication infrastructure components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 Series Ordering Guide to confirm exact pin count and plating specifications. Ensure compatibility with target PCB thickness limits before procurement. Confirm RoHS compliance status via official documentation. Cross-reference the DigiKey or Mouser part numbers with the EDAC catalog to avoid substitution errors during sourcing.

Selection Notes

Select this component when a dual-sided connection with 62 positions is required. Verify that the mating card thickness falls within the 0.054 to 0.070 inch range. Consider the 0.156 inch spacing for layout constraints. Evaluate the need for gold plating versus tin based on environmental exposure and cycle life requirements compared to other series variants.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors. The series includes various configurations differing in position counts, such as 30-position and 86-position variants. These connectors are engineered for general-purpose applications across industrial, medical, and communication sectors, emphasizing mechanical stability and electrical reliability.

Replacement Considerations

Direct substitutes within the same series include parts like 306-031-421-101 or 306-031-421-103 variations if available. Verify identical pin counts, spacing, and mounting styles before substitution. Alternative series may require mechanical re-engineering of the enclosure.
