Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure correct flange and termination specifications. Confirm RoHS compliance status and REACH restrictions prior to procurement. Cross-reference the Mouser or DigiKey part numbers for accurate availability and lead time information as distribution channels may vary.

Edgeboard Connectors Selection Notes

Select this component when a high-density vertical connection is required for dual-edge boards. Ensure the design accommodates the 0.156-inch pitch and 1.57-millimeter board thickness. Verify that the application environment remains within the specified -40°C to +105°C temperature range and requires a 5-ampere current capacity per contact.
