305-030-500-203

Edgeboard Connectors Overview

The EDAC Inc. 305-030-500-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 30 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 gold-plated copper alloy contacts and employs a solder lug termination method. The unit is rated for 5 A current and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for reliable signal transmission
• Low-profile thermoplastic polyester insulator body designed for panel mounting
• Accepts standard 1.57 mm thick PCBs with semi-波纹管 contact type

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific mounting style and termination type against project requirements, as the 305 series includes both panel mount headers and PCB mount receptacles. Confirm that the supplier provides official datasheets matching the exact suffix code to ensure compatibility with the intended PCB thickness and electrical ratings. Cross-reference the manufacturer's ordering guide to validate the correct part number for the required position count and contact finish.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount header is required for dual-edge cards. Ensure the application environment stays within the specified -40°C to +105°C operating range. Verify that the PCB thickness falls within the acceptable tolerance of 1.37 mm to 1.78 mm. Consider the 5 A current rating and 5 GOhms insulation resistance for circuit design constraints.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various pitch options and mounting styles for card edge applications. The series is characterized by its robust construction and standardized dimensions, facilitating interchangeability within industrial designs. The 305-030 variant specifically addresses needs for moderate density connections requiring high reliability in panel-mounted configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 30-position counts and panel-mount specifications, such as 305-030-520-268, provided the termination style matches the assembly process.
