305-042-500-208

Edgeboard Connectors Overview

The EDAC 305-042-500-208 is a standard card edge connector from the 305 series, designed for panel mount applications. It features 42 positions arranged in a dual row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes gold-plated copper alloy contacts and employs a solder lug termination type. The unit is rated for 5 A continuous current and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body constructed from thermoplastic material
• Provides reliable electrical connection through gold-plated copper alloy contacts

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring robust card edge interfaces
• Industrial control systems utilizing standardized PCB modules
• Test and measurement equipment with modular card architectures

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness, insulation color, and flange characteristics. Ensure compatibility with the target PCB thickness of 1.57 mm and confirm that the solder lug termination aligns with the assembly manufacturing process. Cross-reference the part number with the latest ordering guide to validate availability and lead times directly with the manufacturer or authorized distributors.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 42-position interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing high-density connections without excessive board space consumption. Consider the 5 A current rating and wide operating temperature range for environments demanding stable performance. Verify that the polarizing key acceptance feature meets the mechanical stability requirements of the system design.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series of standard card edge connectors, which are engineered for general-purpose interconnect solutions. The series offers various position counts and termination styles to accommodate diverse PCB designs. The 305-042 variant specifically addresses needs for moderate pin counts in dual-row configurations, providing a balance between connectivity density and mechanical robustness for industrial and commercial electronics.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-042-500-504 and 305-042-520-202. These alternatives share identical positional and dimensional specifications but may differ in termination style or housing material properties. Confirm that any replacement maintains the 1.57 mm board thickness tolerance and 3.96 mm pitch to ensure mechanical fit and electrical continuity.
