305-030-556-258

Edgeboard Connectors Overview

The EDAC Inc. 305-030-556-258 is a dual-row female card edge connector designed for board-edge mounting. It features 30 positions with a 0.156-inch (3.96mm) contact spacing and a 0.140-inch row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Contacts are made of copper alloy with gold plating, housed in a green thermoplastic polyester insulator. It supports solder termination and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration for high-density interconnect applications
• Gold-plated contacts ensure reliable signal transmission
• Low-profile insulator body design for space-constrained environments

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 305 Series Ordering Guide to confirm exact pin count, plating thickness, and mounting style. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm RoHS compliance status if required by project specifications. Cross-reference the part number with official distributor catalogs to validate availability and lead times before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with 0.156-inch spacing is required for non-specified dual-edge cards. Consider the 0.062-inch board thickness limitation during mechanical design. Evaluate the operating temperature range of -40°C to 105°C against environmental conditions. Compare alternative series such as 315 or 357 if different mounting styles or row spacings are needed.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options including panel mount and board-edge configurations. The series provides multiple position counts and contact spacing options to accommodate diverse electronic assembly requirements. The 305 Series is characterized by its low-profile design and durable construction suitable for repeated insertion cycles.

Edgeboard Connectors Replacement Considerations

The 305-030-556-201 is a similar 50-position variant within the same series but differs in pin count. For direct replacement, verify that the substitute part matches the 30-position requirement and 0.156-inch spacing. Check datasheets for identical mechanical dimensions and electrical ratings to ensure interchangeability.
