1053122204

Headers, Male Pins Overview

The Molex 1053122204 is a Nano-Fit series vertical header connector designed for through-hole PCB mounting. It features a 4-position, 2-row configuration with a 2.50mm (0.098 inch) mating pitch. The contacts are male pins with a square shape and gold plating thickness of 15.0µin (0.38µm) on the mating interface, while the post section is tin-plated. Constructed from brass contacts and liquid crystal polymer (LCP) insulation, it includes a four-wall shielded housing and a latch bracket for secure retention. The contact length measures 0.126 inches (3.20mm), and the insulation height is 0.356 inches (9.05mm).

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify that the specific order matches the Nano-Fit 105312 series designation to ensure correct pin count and pitch compatibility. Confirm that the receiving PCB footprint aligns with the specified 2.50mm spacing and through-hole termination requirements. Check for any updated environmental compliance declarations or RoHS status changes directly from the manufacturer's official documentation before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a vertical orientation is required for space-constrained designs involving four signal lines. The Nano-Fit series offers a balance of density and robustness suitable for general-purpose applications. Ensure the mating cable or wire gauge is compatible with the terminal specifications. Consider the four-wall shielding if electromagnetic interference protection is necessary for the specific circuit environment.

Headers, Male Pins Part Context

This part belongs to the Nano-Fit Power Connectors product line, which focuses on high-density interconnect solutions for various industries. The 105312 series specifically addresses the need for vertical headers in compact electronic assemblies. Molex designs these connectors to support reliable electrical performance in demanding environments, serving as a critical link between printed circuit boards and external wiring harnesses.

Headers, Male Pins Replacement Considerations

Direct substitutes must maintain the 2.50mm pitch, 4-position count, and vertical through-hole format. Verify that alternative headers match the LCP insulation material and brass contact composition for equivalent thermal and electrical characteristics. Cross-reference with other Nano-Fit variants only if they share identical mechanical dimensions and locking mechanisms.
