346-99-139-41-012000

Headers, Receptacles, Female Sockets Overview

The Mill-Max 346-99-139-41-012000 is a single-row IC socket designed for press-fit termination. It features 39 positions with a 0.100-inch (2.54mm) grid spacing. The contacts are constructed from beryllium copper and plated with gold over nickel to ensure reliable signal transmission. This component utilizes a solderless press-fit mounting method, allowing for direct insertion into printed circuit board plated through-holes without the need for soldering.

Headers, Receptacles, Female Sockets Feature Summary

• Solderless press-fit termination eliminates soldering requirements
• Gold-plated beryllium copper contacts for conductivity
• Single-row configuration for compact layout

Headers, Receptacles, Female Sockets Applications

• IC socket applications requiring press-fit installation
• High-reliability interconnects in multilayer boards
• Prototyping and production environments avoiding thermal stress

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the target PCB design supports solderless press-fit technology rather than standard wave or reflow soldering. Confirm that the plated through-hole dimensions match the specific tolerance requirements of the 346 series contact tails to prevent mechanical stress on inner board layers during insertion.

Headers, Receptacles, Female Sockets Selection Notes

Select this model when a non-soldered connection is required for a 39-position interface. Ensure the application environment does not demand RoHS compliance, as this specific part number is identified as containing lead. Compare against the 304 series if different tail geometries or drill size requirements are necessary for the specific PCB stack-up.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Mill-Max 346 series, which specializes in .100 inch grid solderless press-fit sockets. These parts are engineered to conform to plated through-holes without stressing the inner layers of multilayer boards, distinguishing them from standard solderable sockets.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same series include variations such as 346-99-120-41-012000 for different pin counts. Verify compatibility with existing tooling and PCB hole patterns before swapping between similar series numbers.
