22182191

Headers, Receptacles, Female Sockets Overview

The Molex 22182191 is a KK 254 series PCB header connector designed for top entry and end-to-end stackable applications. It features 19 circuits with cat ear terminals and utilizes 0.38µm gold plating on the contact surfaces to ensure reliable electrical performance in high-density circuit board assemblies.

Headers, Receptacles, Female Sockets Feature Summary

• Top entry configuration facilitates vertical mounting on printed circuit boards
• End-to-end stackable design allows for multi-row expansion without additional spacing hardware
• Cat ear terminal geometry provides enhanced mechanical retention within mating receptacles

Headers, Receptacles, Female Sockets Applications

• High-density electronic assembly interconnects
• Multi-layer PCB stacking systems
• Consumer electronics internal wiring harnesses

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific order matches the 19-circuit requirement and KK 254 pitch specifications. Confirm that the gold plating thickness meets the application's corrosion resistance standards. Ensure compatibility with mating receptacles from the same series family to maintain proper alignment and retention force.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when vertical board space is limited due to the top entry profile. The end-to-end stackability makes it suitable for applications requiring increased I/O density in a compact footprint. Verify that the 0.38µm gold plating is sufficient for the intended environmental conditions and mating cycle requirements.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to the KK 254 product line, which is characterized by a 2.54mm (0.1 inch) pitch. The series is widely used in general-purpose electronics for its balance of cost-effectiveness and reliability. The specific model represents a standard header variant within this extensive ecosystem.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible replacements must match the 2.54mm pitch, 19-circuit count, and top entry orientation. Verify that alternative suppliers offer equivalent gold plating thickness and cat ear terminal designs to ensure mechanical interchangeability.
