Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes to ensure correct terminal style and orientation. Confirm that the target printed circuit board layout matches the specified 0.156-inch pitch and dual-edge card requirements. Check RoHS compliance status against specific project environmental regulations before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface is required for thick cards within the specified thickness tolerance. Ensure the application environment does not exceed the rated temperature limits. Verify that the surface mount footprint aligns with the manufacturer's recommended land pattern for secure mechanical retention.

Edgeboard Connectors Part Context

This model belongs to the EDAC 837 Series, which specializes in standard card edge connectors. The series offers various configurations for single and dual-edge cards. This specific variant provides a high-contact count solution suitable for complex data processing or power distribution tasks in compact form factors.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 837 series parts sharing the same 56-position dual-row specification. Verify identical pitch dimensions and mounting styles before substituting. Ensure any alternative maintains the same thermal and electrical performance characteristics.
