857-016-440-204

Edgeboard Connectors Overview

The EDAC Inc. 857-016-440-204 is a standard card edge connector featuring 16 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and is designed for non-specified dual-edge cards. The connector employs female contacts with tin plating on copper alloy substrates. Termination is achieved through wire wrap connections, and the unit is housed in a black thermoplastic polyester insulator.

Edgeboard Connectors Feature Summary

• Dual-row construction supporting 16 signal positions
• Tin-plated female contacts for reliable signal transmission
• Wire wrap termination method for secure board attachment
• Black thermoplastic polyester housing material

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Consumer electronic circuit board interfaces
• Medical device internal connectivity

Edgeboard Connectors Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official EDAC documentation. Confirm that the specific ordering suffix matches the required tin plating and dual-edge specifications. Ensure compliance with relevant environmental standards such as RoHS before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 16 positions is required. The 3.96 mm pitch dictates compatible PCB trace layouts. Verify that the target application supports wire wrap termination techniques and operates within the thermal limits of the thermoplastic polyester housing material.

Edgeboard Connectors Part Context

This component belongs to the EDAC 857 series of card edge connectors. The series provides various row counts and termination options. The 857 designation indicates a standard profile connector suitable for general-purpose electronic assemblies requiring robust mechanical retention and electrical continuity.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 857 series variants with matching 16-position dual-row configurations. Ensure replacement parts maintain identical 3.96 mm spacing and wire wrap termination capabilities to preserve board compatibility.
