305-076-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-076-521-201 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 76 positions with a 0.156-inch (3.96 mm) pitch and supports a maximum current rating of 5 A. The contacts are gold-plated copper alloy with a semi-bellows termination type, ensuring reliable signal transmission. The housing is green thermoplastic polyester, rated for operation between -40°C and +105°C. This through-hole solder mount receptacle accommodates board thicknesses within specified mechanical limits.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct orientation and termination style. Confirm that the target PCB thickness falls within the connector's mechanical acceptance range. Check RoHS compliance status against current regulatory requirements for the destination market. Ensure storage conditions maintain integrity before assembly.

Edgeboard Connectors Selection Notes

Select this component when a 76-position dual-edge interface is required with a 3.96 mm pitch. Consider the 5 A current rating and -40°C to +105°C temperature range for environmental suitability. Verify compatibility with the specific card edge profile and mounting constraints of the host system.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which provides standardized card edge solutions. The series offers various position counts and termination options. The 305-076 variant specifically addresses applications needing moderate density with robust mechanical retention via solder pin termination.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for alternative position counts. Verify mechanical dimensions and electrical ratings against existing designs before substitution.
