305-050-556-558

Edgeboard Connectors Overview

The EDAC Inc. 305-050-556-558 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 50 positions with a 0.156-inch (3.96 mm) contact spacing and 0.140-inch (3.56 mm) row spacing. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). It utilizes female contacts with gold plating and employs surface mount termination. The insulator body is green thermoplastic polyester, providing a low-profile design suitable for panel mounting.

Edgeboard Connectors Feature Summary

• Dual-edge female connector configuration for non-specified card types
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body facilitates compact panel installations
• Surface mount solder lug termination for secure PCB attachment

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control module connections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm terminal type and insulation color. Ensure the target PCB thickness aligns with the 0.062-inch nominal specification. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Cross-reference the complete part number against distributor catalogs to avoid variant mismatches.

Edgeboard Connectors Selection Notes

Select this component for applications requiring dual-edge connectivity with surface mount capabilities. The 0.156-inch pitch suits high-density layouts where space efficiency is critical. Consider the vertical orientation and panel-mount style for structural integration. Evaluate thermal requirements against the -40°C to +105°C operating range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and termination styles. The 305-050-556-558 specifically denotes a 50-position dual-edge variant with surface mount terminals and green insulation, distinct from single-edge or through-hole versions in the same family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the EDAC 305 Series include 305-050-556-502 and 305-050-556-201. Verify that alternative part numbers match the required surface mount termination and dual-edge configuration before substitution.
