Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact mechanical dimensions and plating specifications. Confirm availability status through authorized distributors as supply chain conditions may vary. Ensure compatibility with target PCB thickness and mounting requirements before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel-mounted installations. Verify that the application environment falls within the specified operating temperature range. Ensure the mating card meets the dimensional tolerances for the 1.57 mm nominal thickness specification.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and configurations for board-to-board or cable-to-board connections. The 305 series is characterized by its robust construction and standardized electrical ratings suitable for general industrial electronics.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-028-520-502 for potential mechanical differences. Verify that any substitute maintains the same 3.96 mm pitch and dual-row configuration. Consult official substitution guides for confirmed equivalent part numbers.
