Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to confirm mechanical dimensions and contact plating specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with distributor catalogs to validate current availability and standard packaging quantities.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required for panel or through-hole installation. It is suitable for applications needing a 5A current rating and operation up to 105°C. Consider the 26-position count and green housing color for visual identification. Verify that the target card thickness falls within the specified 0.054 to 0.070-inch range for proper engagement.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and mounting styles. The 305-026-521-203 variant specifically addresses needs for dual-edge female connections with gold contacts. It is part of a broader portfolio including medical and agricultural interconnect solutions from EDAC Inc.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with different position counts or mounting angles. No alternative manufacturer part numbers are confirmed in public documentation. Ensure replacement parts maintain the same 0.156-inch pitch and dual-edge female configuration.
