399-41-002-21-300000

Headers, Receptacles, Female Sockets Overview

The 399-41-002-21-300000 is a surface mount header connector from the Mill-Max 399 series. It features two positions with a 1.27mm (0.050 inch) pin spacing. The connector utilizes beryllium copper contacts with a tin plating finish. Designed for vertical mounting, it supports a maximum current rating of 3A and operates within a temperature range of -55°C to +125°C.

Headers, Receptacles, Female Sockets Feature Summary

• Surface mount construction for automated PCB assembly
• Spring-loaded interconnect design for uneven mating surfaces
• Vertical orientation for compact board integration

Headers, Receptacles, Female Sockets Applications

• Test and measurement equipment requiring reliable probe connections
• Embedded systems with floating height mating requirements
• Harsh environment electronics needing robust interconnects

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific ordering suffix matches the required contact length and termination style. Confirm surface mount pad layout compatibility with your PCB design. Ensure the tin plating specification meets your corrosion resistance needs. Check RoHS compliance status against current regulatory requirements for your target market before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when spring-loaded performance is necessary for maintaining connection integrity on non-planar surfaces. The 1.27mm pitch suits high-density applications where standard headers are insufficient. Consider the 3A current rating against your system's power requirements. Evaluate the vertical profile constraints of your enclosure design to ensure adequate clearance for mating components.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 399 series of spring-loaded interconnect headers. These connectors are engineered for field-proven reliability in demanding conditions. The series utilizes proprietary manufacturing techniques to ensure consistent performance. This specific model represents a low-pin-count variant suitable for specialized interface applications.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 2-position count, 1.27mm pitch, and surface mount configuration. Verify identical spring-loaded functionality if mating surface variations exist in the application. Cross-reference electrical ratings and operating temperature ranges to ensure equivalent performance capabilities without compromising system reliability.
