Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with your PCB layout. Ensure that the dual-edge requirement matches your board design, as single-edge variants exist within the same series. Cross-reference the pin count and pitch specifications with your assembly drawings before procurement to prevent integration errors.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for high-density applications. The 3.96 mm pitch accommodates larger boards compared to finer pitches. Consider the operating temperature range up to 125°C for environments requiring higher thermal resilience than standard industrial ratings.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 857 series, which specializes in standard card edge solutions. The series offers various position counts and termination styles. The 857-086-500-201 specifically addresses needs for robust, dual-sided connections in compact form factors, serving as a critical interface point in modular electronic systems.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC 857-086-558-201 and 857-086-524-202, which share similar dual-edge characteristics and pitch dimensions. Verify mechanical fit and electrical ratings before substitution.
