305-042-500-204

Edgeboard Connectors Overview

The EDAC Inc. 305-042-500-204 is a standard card edge connector from the 305 series, designed for dual female connections with 42 positions. It features a 3.96 mm (0.156 inch) pitch and utilizes gold-plated copper alloy contacts for reliable signal transmission. The connector supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. It employs a solder eyelet termination method and is constructed with a thermoplastic insulator. The unit is configured for panel mounting at a vertical angle, accommodating specific board thicknesses.

Edgeboard Connectors Feature Summary

• Dual row configuration providing 42 contact positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure durable electrical performance and corrosion resistance
• Vertical panel mount design with solder eyelet termination for secure mechanical installation
• Thermoplastic insulation material supports operation across a wide industrial temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized connector pitches
• Test and measurement instrumentation needing reliable vertical mounting solutions
• Automotive electronics assemblies demanding high durability

Edgeboard Connectors Procurement Notes

Verify the complete part number against manufacturer datasheets to confirm pin count, pitch, and termination style match system requirements. Ensure compatibility with specified PCB thickness and mounting constraints. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference ordering suffixes to validate specific housing colors or flange options provided by the supplier.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with a 3.96 mm pitch is required for vertical panel mounting. The 42-position capacity suits applications needing moderate density without excessive footprint. Verify that the 5 A current rating meets circuit load demands. Consider the solder eyelet termination for through-hole PCB integration and check operating temperature limits against environmental conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial electronics. The series offers various position counts and termination styles to accommodate different board designs. The 305-042 variant specifically provides a balanced solution for mid-range I/O requirements, balancing contact density with mechanical stability in panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 42-position dual female specifications and 3.96 mm pitch. Variants such as 305-042-520-202 offer similar electrical characteristics but may differ in housing color or flange details. Always verify mechanical dimensions and termination type before substitution to ensure PCB compatibility.
