305-074-555-507

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-507 is a standard card edge connector from the 305 series, designed for dual-edge mating with non-specified cards. It features 74 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector supports PCB thicknesses between 1.37 mm and 1.78 mm. Contacts are gold-plated copper alloy with a half-bead type, rated for 5 A current. It utilizes solder pin termination for panel mount installation.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm plating specifications and flange characteristics. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status through manufacturer datasheets. Validate that the selected variant matches the required contact row count and pitch dimensions for the intended application.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card interface with 74 positions is required. The 3.96 mm pitch accommodates standard board layouts. Verify that the operating temperature range of -40°C to +105°C meets environmental requirements. Ensure the panel mount style aligns with the mechanical housing design. Confirm that the 5 A current rating satisfies the electrical load demands of the circuit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options. These connectors are engineered for high-reliability applications requiring robust electrical connections. The 305 series is widely used in industrial and commercial electronics for modular board integration.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants having identical 74-position dual-row configurations. Verify matching pitch and PCB thickness tolerances. Ensure equivalent current ratings and material compositions. Consult official substitution guides for compatible alternatives within the same product family.
