305-018-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-018-521-501 is a dual-edge female card edge connector from the 305 series, designed for through-hole mounting. It features 18 positions with a 0.156" (3.96mm) pitch and semi-bellows contact type. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness and thermoplastic polyester insulation. It supports board thicknesses of 0.054" to 0.070" and operates within a temperature range of -40°C to 105°C.

• Dual-edge female configuration with semi-bellows contacts for secure mating
• Gold-plated copper alloy terminals ensure reliable conductivity
• Thermoplastic polyester insulation provides structural stability

Edgeboard Connectors Applications

• General-purpose electronic interconnects
• Industrial control systems
• Consumer electronics assemblies

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's ordering guide to confirm exact pin count, plating thickness, and termination style. Ensure compatibility with the target PCB board thickness specifications before procurement. Cross-reference the RoHS status and environmental compliance data with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156" pitch is required. Confirm that the application environment falls within the specified -40°C to 105°C operating range. Verify that the PCB design accommodates the through-hole mounting style and the specific board thickness constraints defined by the connector's contact length.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. The 305-018 variant specifically addresses applications requiring 18 positions in a dual-row arrangement, providing a standardized interface solution within the broader family of edgeboard connectors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series Ordering Guide for verified substitute part numbers. Direct replacements must match the 18-position count, 0.156" pitch, and dual-edge female configuration. Verify mechanical dimensions and electrical ratings before substitution.
