305-072-556-501

Edgeboard Connectors Overview

The EDAC Inc. 305-072-556-501 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 72 positions with a 3.96 mm (0.156 inch) pitch and a 3.56 mm (0.140 inch) row spacing. The connector utilizes gold-plated copper alloy contacts and a green thermoplastic polyester housing. Rated for 5 A current, it supports PCB mounting with solder pin termination. The unit accommodates board thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes to confirm specific plating thickness and flange dimensions. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure mating card edge thickness falls within the specified 1.37 mm to 1.78 mm range for proper mechanical engagement. Cross-reference the latest datasheet for any updates to material specifications or environmental ratings.

Edgeboard Connectors Selection Notes

Select this component when dual-edge connectivity with a 3.96 mm pitch is required. The 72-position count suits moderate-density interface needs. Verify that the panel mount style aligns with the enclosure design constraints. Consider the 5 A current rating against the total load requirements of the application. Ensure the operating temperature range meets the environmental conditions of the deployment site.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and mounting styles. The series is characterized by robust construction suitable for harsh environments. Similar models in the series may differ in position count, such as 50 or 72 positions, or mounting orientation. The 305 series generally maintains consistent electrical characteristics across different configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with identical 72-position dual-edge specifications. Models like 305-072-556-502 share similar form factors but may vary in flange details. Verify mechanical compatibility before substitution. No cross-brand replacements are confirmed without extensive re-engineering.
