305-082-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-082-555-203 is a standard card edge connector from the 305 series, designed for dual-edge PCB insertion. It features 82 positions with a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C. Contacts are made of copper alloy with gold plating, housed in a green thermoplastic polyester insulator.

Edgeboard Connectors Procurement Notes

Verify the specific position count and termination type against the official EDAC datasheet before ordering, as the 305 series includes various configurations. Confirm that the target PCB thickness falls within the specified acceptance range of 1.57 mm nominal. Ensure compatibility with the required panel mounting hardware and verify environmental compliance requirements such as RoHS status for the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required with a 3.96 mm pitch. The 82-position configuration suits applications needing substantial I/O density in a single connector footprint. Consider the 5 A current rating and wide temperature range for robust industrial environments. Verify that the board thickness matches the connector's mechanical constraints to ensure proper engagement and retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options, including solder pin and solder lug types. The 305 series is characterized by its durable construction and consistent 3.96 mm spacing, making it suitable for general-purpose electronic interconnections where reliability and ease of insertion are prioritized.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pitch and row count but different position numbers or termination styles, such as 305-082-520-203 if solder pin termination is acceptable. Cross-series replacements require matching the 3.96 mm pitch and dual-row configuration while verifying mechanical fit and electrical ratings.
