857-044-457-101

Edgeboard Connectors Overview

The EDAC Inc. 857-044-457-101 is an 88-position female edgeboard connector designed for dual-edge card insertion. It features a 0.156-inch (3.96mm) spacing and utilizes tin-plated contacts on a copper alloy base. The housing is black, non-specified card type compatible with standard dual-edge PCBs.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for secure board retention
• Tin-plated surface finish for reliable conductivity
• Standardized 0.156-inch pitch for broad compatibility

Edgeboard Connectors Applications

• Industrial equipment interface connections
• General-purpose PCB edge mounting
• Electronic module interconnects

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version against the manufacturer's current documentation to confirm mechanical tolerances and material specifications. Ensure the ordering suffix matches the required termination style and insulation color. Cross-reference the pin count and row configuration with the target PCB design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 88 positions is required. Confirm that the PCB thickness aligns with the connector's retention capabilities. Verify that the tin plating meets the environmental and electrical performance needs of the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 857 series of low-profile edgeboard connectors. The series offers various position counts and termination styles. The 857-044-457-101 specifically denotes the 88-position variant with dual-edge female contacts and standard black insulation.

Edgeboard Connectors Replacement Considerations

Check for direct substitutes within the EDAC 857 series that match the 88-position count and dual-edge female configuration. Verify mechanical footprint and pin spacing compatibility before substituting.
