345-070-542-678

Edgeboard Connectors Overview

The EDAC Inc. 345-070-542-678 is a standard card edge connector from the 345 series, designed for through-hole mounting with a right-angle orientation. It features a dual female configuration with 70 positions and a 0.100" (2.54mm) pitch. The connector supports single-edge board types with a thickness range of 0.054" to 0.070" (1.37mm to 1.78mm). Contacts are made of copper alloy with gold plating, rated for 3A current. The housing is green thermoplastic polyester, operating between -40°C and 105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for reliable signal transmission

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact pin count and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Cross-reference RoHS compliance status with current manufacturer declarations. Confirm lead times directly with authorized distributors as they may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided card edge interface is required for single-edge boards. The 70-position count suits high-pin-count applications. Verify that the 0.100" pitch matches the design footprint. Ensure the right-angle form factor aligns with spatial constraints on the assembly.

Edgeboard Connectors Part Context

This part belongs to the EDAC 345 series of standard card edge connectors. The series offers various position counts and configurations for diverse electronic needs. The 345-070 variant specifically addresses requirements for higher density connections in compact spaces while maintaining standard pitch dimensions for broad compatibility.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and position counts but different termination styles or flange options. Verify mechanical fit and electrical ratings before swapping. Consult EDAC cross-reference guides for approved alternatives.
