305-038-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-038-500-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 38 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). It utilizes copper alloy contacts with gold plating and offers a current rating of 5 A. The unit employs a solder lug termination style and is intended for panel mounting in a vertical orientation.

Edgeboard Connectors Feature Summary

• Dual-row configuration supporting non-specified dual-edge PCBs
• Low-profile insulator body constructed from thermoplastic material
• Gold-plated copper alloy contacts for reliable signal transmission
• Panel mount design with vertical installation angle

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge board connections
• Telecommunications equipment utilizing dual-edge module interfaces
• Test and measurement instrumentation with standardized card formats
• Automotive electronics assemblies needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm the exact termination style and mounting configuration, as variations exist within the 305 series. Confirm that the target PCB thickness aligns with the 1.57 mm nominal specification to ensure proper mechanical engagement. Check regional availability restrictions, as distribution channels may limit sales in certain territories. Ensure compliance with RoHS3 and REACH regulations if required by the end application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, panel-mount solution is required for thick PCBs. The 3.96 mm pitch suits applications where higher current capacity and mechanical stability are prioritized over dense packing. Verify that the vertical mounting style fits the enclosure constraints. Consider the 5 A current rating against the total load requirements of the connected circuitry to prevent thermal issues during operation.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which provides a range of standard card edge connectors. The series is characterized by its durable construction and compatibility with various PCB thicknesses. The 305-038-500-203 specifically addresses needs for 38-position interfaces, offering a balance between connectivity density and mechanical robustness for industrial-grade environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with matching 38 positions and 3.96 mm pitch, such as the 305-038-520-203, provided the mounting and termination styles are compatible. Cross-brand replacements require careful verification of pinout, mechanical dimensions, and electrical ratings to ensure functional equivalence without redesigning the host PCB.
