346-44-138-41-013000

Headers, Receptacles, Female Sockets Overview

The Mill-Max 346-44-138-41-013000 is a single-row IC socket featuring 38 positions with a 0.100-inch (2.54mm) pitch. It utilizes press-fit termination for through-hole mounting and includes compliant tail pins designed to conform to plated through-holes without stressing multilayer board inner layers. The contacts are made of copper beryllium with gold plating, while the column terminals use copper alloy with tin plating. The housing is constructed from PCT polyester with a UL94 V-0 flammability rating, supporting operation between -55°C and 125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Compliant tail pins ensure reliable connection to plated through-holes without mechanical stress on multilayer PCBs
• Press-fit termination provides secure installation without soldering requirements
• Gold-plated contact surfaces offer durable electrical performance in high-cycle applications

Headers, Receptacles, Female Sockets Applications

• IC socketing for microprocessors and memory modules
• Development board prototyping requiring frequent component changes
• Industrial control systems needing high-reliability interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the target PCB design accommodates the specific drill hole diameter required for the 346 series compliant tails. Confirm that the assembly process supports press-fit installation methods rather than standard wave or reflow soldering. Ensure compatibility with the specified contact materials and insulation ratings for the intended operating environment.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a non-soldered, high-cycle life socket is required for 38-pin ICs. The press-fit mechanism eliminates thermal stress associated with soldering, making it suitable for components sensitive to heat cycles. Verify that the 2.54mm pitch aligns with the footprint of the integrated circuit being socketed.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 346 series, which specializes in single-row SIP sockets utilizing press-fit technology. The series is engineered for applications demanding repeated insertion cycles and robust mechanical retention. It serves as an alternative to traditional soldered sockets where board integrity and thermal management are critical concerns.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and termination styles, such as the 346-44-133-41-013000 for 33 positions. Cross-series replacements require verification of the compliant tail drilling specifications and press-fit force requirements.
