305-030-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-030-555-203 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features a dual-edge female configuration with 30 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. The insulator body is made of thermoplastic polyester, providing stability across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Low-profile insulator body facilitates compact panel integration
• Vertical panel mount style with solder lug termination

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, termination type, and flange characteristics. Ensure compatibility with the target PCB thickness of 0.062 inches (1.57 mm) and verify that the gold plating specification meets the required environmental standards for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mounted solution is required for double-sided cards. The 0.156-inch pitch suits high-density layouts where space efficiency is critical. Confirm that the 5A current rating aligns with the power distribution requirements of the connected circuitry and that the operating temperature range covers the expected environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which offers various row counts and termination options. The series is characterized by its robust construction and suitability for harsh environments. The 305-030-555-203 specifically provides a mid-range position count, balancing connectivity density with physical footprint constraints in modular electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-030-520-203 or 305-030-556-203 if different termination styles or flange configurations are needed. Verify that any substitute maintains the same 0.156-inch pitch and 1.57mm board thickness acceptance to ensure mechanical fit.
