305-018-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-018-521-558 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features 18 positions arranged in a dual row configuration with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder lug termination for secure electrical connection. It supports a maximum current rating of 5 A and operates within a temperature range of -40°C to +105°C. The housing is constructed from green thermoplastic material, providing insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify part authenticity through authorized EDAC distributors or official manufacturer channels. Confirm RoHS compliance status and REACH registration details prior to integration. Ensure storage conditions maintain component integrity. Cross-reference ordering suffixes to match specific packaging requirements. Validate technical specifications against the latest official datasheet documentation before procurement finalization.

Edgeboard Connectors Selection Notes

Select this model when a 18-position dual-row connector with 3.96 mm pitch is required. Verify that the target PCB thickness falls within the specified operational range. Ensure the application environment remains within the -40°C to +105°C temperature limits. Confirm compatibility with gold-plated contact mating surfaces. Consider panel mounting constraints and vertical orientation requirements during mechanical design integration.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent 3.96 mm pitch dimensions. The 305 series is engineered for durability in demanding environments, featuring thermoplastic housings and gold-plated contacts. This specific variant represents a mid-range position count option within the broader product family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with identical 3.96 mm pitch and 18-position dual-row configurations. Verify matching termination types and mounting styles when evaluating alternatives. Ensure replacement parts maintain equivalent current ratings and temperature specifications.
