Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to ensure correct contact plating, insulation color, and flange specifications. Confirm that the target PCB thickness aligns with the 1.57 mm requirement for proper mechanical fit. Check regional distribution availability as stock levels vary by distributor. Ensure compliance with RoHS3 standards if required for the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a 28-position dual-row interface is required for vertical panel mounting. The 3.96 mm pitch suits applications needing robust spacing between contacts. Consider the 5 A current rating and -40°C to +105°C operating range for environmental suitability. Verify compatibility with the specific card edge thickness and mating connector requirements before integration.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability in demanding environments. The series offers various position counts and configurations, all sharing common mechanical and electrical characteristics such as the 3.96 mm pitch and panel mount style. The 305-028-521-203 represents a specific variant optimized for 28-position applications.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or flange options. Cross-reference with other manufacturers' 3.96 mm pitch dual-row card edge connectors only if mechanical dimensions and electrical ratings are identical. Verify that any alternative maintains the same vertical panel mount and solder pin termination style.
