Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 305 Series Ordering Guide to ensure compatibility with required polarizing key configurations and mounting styles. Confirm that the target printed circuit board thickness falls within the specified 0.054 to 0.070 inch range for proper mechanical engagement. Cross-reference the RoHS status and environmental compliance data provided in the latest datasheet before final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a dual-row configuration with a 0.156-inch pitch is required for high-current applications up to 5A. Ensure the design accommodates the straddle mount or board edge installation method. Verify that the operating environment remains within the -40°C to 105°C temperature limits. Consider the availability of compatible polarizing keys if precise alignment is critical for the assembly process.
