305-028-520-204

Edgeboard Connectors Overview

The EDAC Inc. 305-028-520-204 is a standard card edge connector header featuring 28 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch with a row spacing of 3.56 mm (0.140 inch). Designed for vertical panel mount installation, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and provides insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination style. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm. Confirm RoHS compliance status through the latest product documentation before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with a 3.96 mm pitch is required for vertical panel mounting. The 5 A current rating and gold contact finish make it suitable for general-purpose signal and power distribution. Ensure the mating card edge thickness aligns with the 0.062 inch specification for proper mechanical retention and electrical contact.

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 options while maintaining consistent dimensional standards. The 305 series is widely used in applications requiring robust, high-density board-to-board or board-to-panel connections with reliable performance under varying environmental conditions.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers within the EDAC 305 series for alternative position counts such as 305-038-520-502. Verify that any substitute maintains the same 3.96 mm pitch, dual-row layout, and vertical panel mount style to ensure mechanical compatibility.
