Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffix codes to ensure correct termination style and contact configuration. Confirm that the specific variant matches the required surface mount or through-hole implementation. Check RoHS compliance status against current regulatory requirements. Ensure compatibility with the target printed circuit board thickness specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a double-row interface with a 3.96 mm pitch is required for high-current or high-reliability applications. The gold-plated contacts offer superior conductivity compared to tin variants. Consider the operating temperature range limits when evaluating thermal management strategies. Verify that the surface mount footprint aligns with the available PCB design constraints and manufacturing capabilities.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 837 High Temperature Series, which is engineered for durability in harsh environments. The series typically features DAP insulators and gold-plated contacts to withstand thermal cycling. The 60-position double-row format allows for significant I/O density within a compact form factor, making it suitable for complex electronic modules where space and reliability are critical factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and row count but different position counts, such as 837-044-556-812 or 837-068-556-807. Cross-series replacements require careful verification of mechanical dimensions and electrical ratings to ensure functional equivalence without redesigning the host board layout.
