Headers, Receptacles, Female Sockets Overview

The Mill-Max 399-41-045-21-300000 is a spring-loaded pogo pin connector designed for board-to-board or board-to-cable applications. It features a single row of 45 contacts with a 0.100-inch (2.54 mm) pitch. The component utilizes a right-angle through-hole mounting style, allowing for vertical mating with compatible spring targets. Contact materials are typically brass alloy with gold plating to ensure reliable signal transmission and low contact resistance in high-cycle environments.

Headers, Receptacles, Female Sockets Feature Summary

• Spring-loaded mechanism provides consistent contact force and accommodates minor misalignments during mating.
• Right-angle orientation facilitates compact vertical integration within electronic assemblies.
• Gold-plated contacts ensure corrosion resistance and stable electrical performance over repeated cycles.

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnects requiring shock and vibration resistance
• Automotive electronics testing fixtures
• Industrial control system I/O modules
• Medical device diagnostic equipment

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact finish thickness and material composition against the official Mill-Max datasheet for the exact suffix configuration. Confirm that the right-angle through-hole footprint matches the target PCB design guidelines. Ensure compatibility with the mating spring target series to guarantee proper insertion depth and electrical continuity.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a robust, high-cycle interconnect solution is required for vertical board stacking. The 45-position count suits complex signal routing needs. Evaluate the operating temperature range and current carrying capacity requirements against the application's thermal profile before finalizing the part number selection.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 399 Series, which specializes in spring-loaded interconnect solutions. The series is engineered for high reliability in demanding environments, offering superior durability compared to standard fixed connectors. The 399-41 variant specifically denotes the right-angle through-hole configuration within this product family.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 45-position count, 2.54 mm pitch, and right-angle through-hole form factor. Verify that any alternative spring-loaded connector maintains equivalent insertion force characteristics and contact material specifications to ensure functional parity in existing designs.
