22182091

Headers, Receptacles, Female Sockets Overview

The Molex 22-18-2091 is a KK 254 PC Board Connector designed for top entry and end-to-end stackable applications. It features a 9-circuit configuration with cat ear terminals and hooks for secure retention. The contacts are plated with 0.38µm gold (Au) to ensure reliable signal transmission. This component supports polarization through offset header entry holes, allowing both power and signal lines to be carried within the same housing structure.

Headers, Receptacles, Female Sockets Feature Summary

• Top entry design compatible with end-to-end stacking configurations
• Integrated hooks provide secure mechanical retention during assembly
• Offset header entry holes enable polarization for mixed power and signal routing

Headers, Receptacles, Female Sockets Applications

• PCB board-to-board interconnections requiring vertical stacking
• Electronic assemblies needing polarized power and signal integration
• Compact consumer electronics utilizing surface-mounted headers

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific ordering suffix against the official Molex datasheet to confirm terminal plating thickness and housing color options. Ensure the selected variant matches the required circuit count and stacking height specifications for your PCB layout. Cross-reference the part number with authorized distributors to confirm current availability status and compliance certifications such as RoHS before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this connector when a low-profile, vertically stacked header solution is required for dense PCB layouts. The KK 254 series offers a balance of electrical performance and mechanical stability suitable for general-purpose electronic applications. Consider the offset hole design if polarization is necessary to prevent mating errors in mixed-signal environments. Evaluate the hook mechanism requirements to determine if additional retention force is needed beyond standard friction fit.
