845-023-542-404

Edgeboard Connectors Overview

The EDAC Inc. 845-023-542-404 is a standard card edge connector from the 845 series, designed for single female mating configurations. It features a .100 inch (2.54 mm) pitch with 23 positions and utilizes gold-plated contacts on copper alloy substrates. The component supports a 3 A current rating and employs solder pin termination for secure board attachment. Constructed with Diallyl Phthalate (DAP) housing, it accommodates a 1.57 mm board thickness and operates within a temperature range of -40°C to +125°C.

Edgeboard Connectors Feature Summary

• Single female contact configuration for reliable card edge mating
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Diallyl Phthalate (DAP) housing provides high thermal stability
• Solder pin termination ensures robust mechanical connection

Edgeboard Connectors Applications

• Industrial control systems requiring high-temperature reliability
• Telecommunications equipment interfaces
• Automotive electronic module connections
• Medical device internal circuit board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB stack-up regarding the 1.57 mm board thickness requirement. Cross-reference the 23-position count with schematic designs to prevent mismatch errors during assembly.

Edgeboard Connectors Selection Notes

Select this connector when a single-row interface with a 2.54 mm pitch is required for high-temperature environments up to 125°C. The DAP housing material offers superior heat resistance compared to standard thermoplastics. Verify that the application does not require double-sided or multi-row configurations, as this model is strictly single female.

Edgeboard Connectors Part Context

This component belongs to the EDAC 845 High Temp Series, which specializes in connectors capable of withstanding elevated operating temperatures. The series is engineered for demanding applications where standard plastic housings might degrade. The 845-023-542-404 variant specifically addresses the need for 23-position connectivity in compact, vertically mounted panel installations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 845 series parts with matching position counts and pitch, such as the 845-023-542-xxx variants. Verify that any replacement maintains the same DAP housing material and gold plating specifications to ensure equivalent thermal and electrical performance.
