392-112-558-203

Edgeboard Connectors Overview

The EDAC Inc. model 392-112-558-203 is a standard card edge connector from the 392 series, designed for reliable signal transmission in electronic assemblies. It features a dual-edge female configuration with 112 positions arranged in two rows. The connector utilizes a 0.100-inch (2.54mm) contact pitch and employs solder terminals for secure board attachment. Constructed with copper alloy contacts featuring gold plating and a black thermoplastic polyester insulator, it supports vertical mounting. This component is engineered to interface with double-sided PCBs, providing robust connectivity for high-density applications.

• Solder terminal termination method for permanent and secure PCB integration

Edgeboard Connectors Applications

• High-density electronic system interconnections
• Industrial control panel backplanes
• Telecommunications equipment signal routing
• Medical device internal board connections

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version for the 392-112-558-203 to confirm exact dimensional tolerances and mating force requirements. Ensure that the target PCB stack-up matches the connector's specified board thickness range. Confirm that the manufacturing facility complies with relevant environmental directives applicable to the end product. Cross-reference the pinout configuration against the system schematic to prevent orientation errors during assembly.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 112-position interface is required with a standard 2.54mm pitch. The choice of gold plating on copper alloy contacts addresses conductivity needs for signal integrity. Consider the vertical mounting style and solder termination method for compatibility with existing assembly processes. Evaluate the thermoplastic polyester material properties against the operational temperature environment of the final application.

Edgeboard Connectors Part Context

This component belongs to the EDAC 392 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and row configurations to suit different density requirements. The 392-112-558-203 specifically addresses the need for high-pin-count interfaces in space-constrained or high-performance systems requiring reliable mechanical retention and electrical continuity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pin counts and row configurations, such as variations in mounting hardware or termination style if permitted by the design. Verify that any alternative part maintains the 0.100-inch pitch and dual-edge female characteristics to ensure mechanical and electrical compatibility without redesigning the PCB footprint.
