22182031

Headers, Receptacles, Female Sockets Overview

Molex part number 22182031 is a KK 254 PC Board Connector designed for top entry and end-to-end stackable applications. This receptacle connector features three circuits with a 0.100 inch (2.54mm) pitch. The terminals are equipped with cat ear features and hooks to secure connections. The mating interface utilizes gold plating with a minimum thickness of 0.38µm to ensure reliable conductivity. It is intended for through-hole termination on printed circuit boards.

Headers, Receptacles, Female Sockets Feature Summary

• End-to-end stackable design allows for compact vertical assembly configurations
• Cat ear terminal geometry provides enhanced mechanical retention within the housing
• Gold-plated contacts ensure stable electrical performance over repeated mating cycles

Headers, Receptacles, Female Sockets Applications

• Through-hole PCB header assemblies requiring stackable form factors
• Electronic devices utilizing 0.100 inch pitch interconnect systems
• Industrial control boards needing secure female socket receptacles

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the required contact count matches the three-circuit specification of this specific part number. Confirm that the application requires a top-entry receptacle style rather than a plug or male variant. Ensure the PCB layout accommodates the through-hole termination style and the physical dimensions associated with the KK 254 series hook and cat ear terminal structure before ordering.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a stackable, three-position female receptacle is required for a 2.54mm pitch system. The choice is driven by the need for top-entry mounting and the specific mechanical retention provided by the cat ear terminals. Consider the gold plating requirement for signal integrity if the application involves sensitive data lines or frequent insertion cycles compared to tin-plated alternatives.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Molex KK 254 series, a widely used line of board-to-board and wire-to-board connectors. The series is characterized by its 0.100 inch spacing and versatile termination options. Part 22182031 specifically represents the receptacle variant designed for PCB mounting, complementing the corresponding plug housings and crimp contacts within the same ecosystem.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes must maintain the 0.100 inch pitch, three-circuit count, and through-hole termination style. Verify that alternative manufacturers offer equivalent cat ear terminal designs and compatible stacking capabilities. Cross-reference the mechanical envelope to ensure fit within existing PCB footprints and housing constraints.
