395-140-540-858

Edgeboard Connectors Overview

The EDAC Inc. 395-140-540-858 is a standard card edge connector featuring 140 positions with dual female contacts. It utilizes a 0.100-inch (2.54mm) pitch and is designed for vertical through-hole mounting. The connector accepts board thicknesses ranging from 0.054 to 0.070 inches. Contacts are gold-plated copper alloy with a 10.0µin thickness, ensuring reliable signal transmission. The insulator is black thermoplastic polyester, rated for operation between -40°C and 105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffix codes against official EDAC documentation to ensure correct pin count, plating specification, and mounting style. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region and manufacturing batch.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for vertical PCB assembly. Ensure the target circuit board thickness falls within the specified 0.054 to 0.070 inch range. Verify that the operating environment temperature remains within the -40°C to 105°C limit and that the 0.100-inch pitch matches the design footprint.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 395 series of standard card edge connectors. The series offers various position counts and configurations for single and dual-edge applications. The 395-140 variant provides a high-contact-count solution for complex signal routing in compact electronic assemblies requiring durable mechanical retention.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for verified equivalents. Generic cross-references may not match specific tail dimensions or flange features. Validate compatibility with existing tooling and board layouts before switching suppliers.
