305-076-520-202

Edgeboard Connectors Overview

The EDAC Inc. 305-076-520-202 is a standard card edge connector from the 305 series, designed for dual-edge mating applications. It features 76 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it provides reliable electrical performance. The housing is made of green thermoplastic polyester, offering durability in industrial environments.

Edgeboard Connectors Procurement Notes

Verify the specific pin configuration and termination style against the official datasheet before procurement. Confirm that the target PCB thickness matches the specified 1.57 mm requirement to ensure proper mechanical engagement. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure the supplier provides genuine EDAC components to maintain signal integrity and mechanical reliability.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 76-position interface. The 3.96 mm pitch is suitable for high-density layouts requiring robust mechanical locking. Consider the vertical panel mount style if space constraints dictate a specific orientation. Verify that the 5 A current rating meets the power distribution needs of the application circuitry.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in demanding industrial and commercial applications. The series offers various position counts and mounting styles to accommodate different system architectures. The 305-076-520-202 specifically addresses the need for a high-pin-count dual-edge solution with standardized dimensions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing, such as the 305-072-520-204 or 305-080 variants, provided the physical footprint and electrical ratings remain compatible with the existing design.
