306-034-520-158

Overview

The EDAC Inc. 306-034-520-158 is a standard card edge connector designed for dual-edge PCB applications. It features 34 contacts arranged in a single row with a female termination type and a 0.156-inch (3.96mm) pitch. The connector utilizes gold-plated copper alloy contacts with a thickness of 10.0µin (0.25µm) and employs a solder termination method. The insulator is green thermoplastic polyester, supporting board thicknesses between 0.054" and 0.070" (1.37mm - 1.78mm). It operates within a temperature range of -40°C to 105°C and includes flange features for panel mounting.

Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Gold-plated suspension arm contacts for reliable signal transmission
• Panel mount design with integrated flanges and top openings
• High-temperature resistant thermoplastic polyester insulation

Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing reliable signal pathways
• Agricultural technology hardware exposed to harsh environments
• General-purpose electronic assemblies utilizing card edge interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure compatibility with required flange types and termination styles. Confirm that the target PCB thickness falls within the specified 0.054" to 0.070" range to guarantee proper mechanical engagement. Check current RoHS compliance status as regulatory requirements may evolve. Ensure storage conditions maintain component integrity prior to assembly.

Selection Notes

Select this model when a dual-edge connection with 34 positions is required. The 0.156-inch pitch dictates the trace spacing on the host PCB. Verify that the application environment stays within the -40°C to 105°C operational limit. Consider the panel mount flange style if space constraints or vibration resistance are critical factors for the installation.

Part Context

This component belongs to the EDAC 306 Series, which provides standard card edge connectors for various industrial and commercial applications. The series offers multiple configurations regarding position count, pitch, and mounting options. The 306-034-520-158 specifically addresses needs for medium-density connections with durable gold plating and flexible panel mounting capabilities.

Replacement Considerations

Consult the official EDAC 306 Series cross-reference documentation for verified substitute part numbers. Ensure any replacement maintains the same 0.156-inch pitch and 34-position count. Verify that alternative models support the same dual-edge board thickness and mounting flange specifications.
