CWR-170-40-0003

Edgeboard Connectors Overview

The CWR-170-40-0003 is a standard card edge connector manufactured by CW Industries. It features a dual female configuration with 40 positions arranged in two rows of twenty contacts each. The connector utilizes a 0.100-inch (2.54mm) centerline spacing and is designed for commercial applications. Contact materials consist of phosphor bronze with a tin-lead finish, lacking ear structures on the board edge interface.

Edgeboard Connectors Feature Summary

• Dual row female contact configuration for board edge insertion
• Phosphor bronze contact material with tin-lead surface finish
• Standard commercial grade construction without shielding

Edgeboard Connectors Applications

• Commercial electronic circuit board interconnections
• Dual-sided card edge mounting systems
• General purpose backplane or daughterboard interfaces

Edgeboard Connectors Procurement Notes

Verify RoHS compliance status carefully as sources indicate conflicting information regarding lead content. Confirm availability through authorized distributors as inventory levels fluctuate. Ensure the specific tin-lead finish requirement aligns with assembly processes. Validate that the non-specified variant meets mechanical retention needs for the target application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with 0.100-inch spacing is required for commercial-grade applications. The tin-lead finish offers reliable solderability but may not suit lead-free manufacturing lines. Consider the absence of ears if board retention via other means is planned. Verify compatibility with 40-position dual-edge card geometries before integration.

Edgeboard Connectors Part Context

This part belongs to the CWR-170 series of edgeboard connectors from CW Industries. The series provides various position counts and configurations for card edge applications. The CWR-170-40-0003 specifically addresses the need for high-density dual-row connections in standard commercial electronics assemblies requiring robust mechanical and electrical performance.

Edgeboard Connectors Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-reference with other CW Industries CWR-170 variants only if pin count and spacing match exactly. Verify mechanical dimensions and contact finish compatibility before considering alternative sourcing options.
