305-028-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-503 is a standard card edge connector designed for panel mounting with a vertical orientation. It features 28 positions arranged in a dual row configuration with a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contact plating is gold, and the termination type utilizes solder pins. The insulating material is thermoplastic, and the unit operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct flange and termination specifications. Confirm that the target application requires the standard 3.96 mm pitch and 1.57 mm board thickness compatibility. Check RoHS compliance status directly from the product documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 28 positions is required. Ensure the design accommodates the 0.156 inch pitch and supports panel mounting constraints. Verify that the operating environment remains within the specified -40°C to +105°C temperature range and that the PCB thickness matches the connector's acceptance criteria.

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 while maintaining consistent 3.96 mm spacing. The 305-028-520-503 specifically provides a 28-position dual-row solution suitable for high-density applications requiring robust mechanical retention and electrical performance.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-028-520-501 or 305-028-520-502 if different flange configurations are needed. Ensure any substitute maintains the same 28-position count, dual-row layout, and 3.96 mm pitch to guarantee mechanical and electrical compatibility.
