399-41-035-21-300000

Headers, Receptacles, Female Sockets Overview

The Mill-Max 399-41-035-21-300000 is a spring-loaded PCB target connector designed for in-circuit testing applications. It features a 35-position single-row configuration with a 0.100-inch (2.54mm) pitch. The component utilizes brass alloy contacts with a gold finish to ensure reliable electrical performance. It supports through-hole mounting and right-angle orientation on the printed circuit board, providing stable contact for test probes during manufacturing verification processes.

Headers, Receptacles, Female Sockets Feature Summary

• Spring-loaded mechanism ensures consistent contact pressure for reliable in-circuit testing
• Gold-plated brass alloy contacts provide corrosion resistance and low contact resistance
• Right-angle through-hole mounting facilitates compact PCB layout integration

Headers, Receptacles, Female Sockets Applications

• In-circuit testing (ICT) fixtures
• Burn-in boards for electronic components
• Functional test jigs for manufactured assemblies

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific ordering suffix matches the required pin count and termination style. Confirm compatibility with standard pogo pin probe diameters used in existing test fixtures. Ensure the right-angle mounting orientation aligns with the mechanical constraints of the assembly design before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, high-density target array is required for vertical probe access. The 2.54mm pitch suits standard board layouts. Consider the right-angle form factor for space-constrained designs where probe access is from above. Validate that the gold plating thickness meets the endurance requirements of the specific test cycle frequency.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 399 series of spring targets, which are passive interconnect components used exclusively as mating points for active pogo pins. Unlike active connectors, these targets do not generate signals but provide a durable, low-resistance interface for automated test equipment to monitor circuit parameters during production.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes must match the 35-position count, 2.54mm pitch, and right-angle through-hole mounting. Verify that alternative spring targets maintain identical contact geometry and plating specifications to ensure probe compatibility and long-term durability in high-cycle test environments.
