305-018-521-212

Edgeboard Connectors Overview

The EDAC Inc. 305-018-521-212 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features an 18-position configuration with two rows of contacts. The connector utilizes a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses ranging from 1.37 mm to 1.78 mm. Constructed with copper alloy contacts featuring gold plating, it ensures reliable signal transmission. The housing is made of green thermoplastic polyester, providing durability in operating temperatures between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for non-specified dual-edge boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required PCB thickness and mounting style. Confirm RoHS compliance status directly with the supplier or through certified documentation prior to procurement. Cross-reference the part number with authorized distributors to validate authenticity and supply chain integrity.

Edgeboard Connectors Selection Notes

Select this component when a vertical, dual-row connection is required for boards with a 3.96 mm pitch. Ensure the target printed circuit board thickness falls within the specified 1.37 mm to 1.78 mm range for proper engagement. Consider the thermal rating of the thermoplastic housing if operation exceeds standard ambient conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which offers various configurations for card edge applications. The series provides options for different row counts, pitches, and mounting styles. This specific model represents a mid-range position count within the series, balancing connectivity density with physical footprint constraints for standard industrial form factors.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 305 Series ordering guide for verified substitute part numbers. Alternative models may differ in contact material, insulation color, or specific PCB thickness tolerances. Verify mechanical dimensions and electrical ratings before substituting.
