305-084-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-203 is a standard card edge connector from the 305 series, designed for reliable signal transmission in electronic assemblies. It features a dual readout configuration with 84 positions and a 3.96 mm (0.156 inch) pitch. The unit supports panel mount installation via through-hole solder termination. Constructed with copper alloy contacts featuring gold plating, it ensures durability and low contact resistance. The housing utilizes thermoplastic material to provide structural integrity and electrical insulation.

Edgeboard Connectors Procurement Notes

Verify part number accuracy against official EDAC documentation before ordering. Confirm that the specific suffix matches the required pin count and mounting style. Check regional availability as distribution may vary. Ensure compatibility with existing PCB layouts and mating card edge specifications. Request updated datasheets to confirm current manufacturing status and compliance certifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 84 positions is required. The 3.96 mm pitch must align with the mating card edge thickness and guide rail specifications. Panel mount orientation should be verified against the enclosure design. Gold plating is necessary for environments requiring high reliability. Ensure the thermal rating of the thermoplastic housing meets the operational temperature range of the target application.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers a wide range of standard card edge solutions. The series is characterized by consistent dimensional tolerances and reliable contact performance across various position counts. The 305-084 variant specifically addresses applications needing higher pin density within the standard 0.156 inch pitch framework established by the family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other 305-series parts with different pin counts but identical pitch and mounting styles. Verify that any replacement maintains the dual readout configuration and gold-plated contact specification. Cross-reference dimensions to ensure fit within the designated panel cutout and enclosure constraints.
