• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct termination style, contact plating, and mounting hardware options. Confirm that the selected variant matches the required board thickness and pitch specifications for your application. Cross-reference the part number with the latest datasheet to validate compliance with current environmental standards and material compositions before finalizing procurement orders.

Selection Notes

Select this component when a dual-edge receptacle with 3.96 mm pitch is required for vertical panel mounting. Ensure the application environment remains within the specified -40°C to +105°C operating temperature range. Verify that the target PCB thickness aligns with the 1.57 mm nominal requirement. Consider the 5 A current rating and 5 GOhms insulation resistance to confirm suitability for the intended electrical load and isolation requirements.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series provides various row configurations, contact spacings, and termination options. The 306-020-400-101 specifically denotes a 20-position dual-edge variant with thermoplastic polyester insulation and tin-plated contacts, distinguishing it from single-row or different pitch alternatives within the broader product family.
