306-033-520-178

Overview

The EDAC Inc. part number 306-033-520-178 is a standard card edge connector from the 306 series, designed for through-hole mounting with a straight installation angle. It features 33 positions arranged in a dual configuration with a contact spacing of 3.96 mm (0.156 inches). The connector utilizes copper alloy contacts with gold plating and is rated for 5 A current. The housing is constructed from thermoplastic polyester, supporting PCB thicknesses between 1.37 mm and 1.78 mm. It operates within a temperature range of -40°C to +105°C.

Feature Summary

• Dual female contact configuration for board-to-board interconnection
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Thermoplastic polyester housing provides thermal stability up to 105°C
• Through-hole solder termination supports robust mechanical attachment

Applications

• Industrial control systems requiring durable edge connections
• Communication equipment interface modules
• Medical device internal circuit boards
• Energy sector instrumentation panels

Procurement Notes

Verify the specific pin count and contact type against the official EDAC datasheet before ordering. Confirm that the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range to ensure proper mating. Check for any regional distribution restrictions or RoHS compliance requirements relevant to your procurement jurisdiction. Ensure the straight mounting style aligns with the mechanical layout constraints of the assembly.

Selection Notes

Select this component when a dual-row card edge connector with 3.96 mm spacing is required for high-reliability applications. The 5 A rating and gold plating make it suitable for environments demanding stable electrical performance. Consider the through-hole termination method if surface mount options are not feasible. Verify compatibility with the mating card's edge thickness and guide rail requirements.

Part Context

This component belongs to the EDAC 306 series, which offers various positioning options and termination styles. The series is characterized by its use of thermoplastic insulators and standardized 0.156-inch pitch. It serves as a standard interconnect solution within EDAC's portfolio for general-purpose electronic assemblies requiring robust mechanical and electrical connections.

Replacement Considerations

Consult the EDAC 306 Series Ordering Guide for direct substitutes with different position counts or termination types. No alternative part numbers are confirmed as functional equivalents without verifying mechanical and electrical parameter alignment.
