Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official Molex datasheet to confirm terminal plating specifications and housing color variants. Ensure that the procurement documentation explicitly references the 219476 series compatibility. Cross-check the current rating requirements against the application load to prevent thermal issues. Confirm compliance with RoHS directives if environmental regulations apply to the end product assembly.

Edgeboard Connectors Selection Notes

Select this connector when a single interface must handle both high-current power delivery and standard signal transmission. The mixed pitch layout reduces board space compared to separate connectors. Verify that the mating card edge thickness matches the 1.57 mm specification. Consider the right-angle through-hole mounting style for PCB layout constraints. Ensure the 47 A current capacity meets the peak operational demands of the power circuit.

Edgeboard Connectors Part Context

This component belongs to the EXTreme PowerEdge Plus series by Molex, engineered for demanding environments. The series emphasizes high current handling capabilities alongside signal integrity. The 219476-0100 variant specifically addresses applications needing compact, high-reliability connections. It serves as a critical interface point in systems where space efficiency and electrical performance are prioritized over modular flexibility.

Edgeboard Connectors Replacement Considerations

No direct public substitute part numbers are confirmed for this specific mixed-pitch configuration. Alternative solutions may require redesigning the PCB footprint due to the unique 7.62 mm and 2.54 mm pitch combination. Verify mechanical compatibility and electrical ratings before considering any generic card edge connectors.
