399-41-032-21-300000

Headers, Receptacles, Female Sockets Overview

The Mill-Max 399-41-032-21-300000 is a spring-loaded PCB target connector designed for in-circuit testing applications. It features a right-angle through-hole mounting configuration with 32 positions arranged in a single row. The unit utilizes a 0.100-inch (2.54mm) pitch to accommodate standard test probe spacing. Contacts are constructed from brass alloy and finished with a 10.0µin (0.25µm) gold plating to ensure reliable signal transmission. The component supports a rated current of 3A and operates within a temperature range of -55°C to 125°C, providing durable performance for repetitive mating cycles.

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific suffix codes against official Mill-Max documentation to confirm exact plating thickness, tip style, and insulation height variations. Ensure the selected variant matches the required current rating and operating temperature range for the intended application environment. Cross-reference the part number with the latest manufacturer catalog to confirm active status and availability before finalizing procurement orders.

Headers, Receptacles, Female Sockets Selection Notes

Select this component based on the 32-position count and 2.54mm pitch requirements for the test fixture design. Confirm that the right-angle form factor aligns with the spatial constraints of the assembly. Evaluate the 3A current rating against peak test loads to prevent overheating. Ensure the gold plating specification meets the signal integrity needs for the specific test points being accessed on the device under test.

Headers, Receptacles, Female Sockets Part Context

This part belongs to the Mill-Max 399 series of spring-loaded targets, which are specialized connectors used primarily in manufacturing and quality assurance environments. Unlike standard headers, these units incorporate internal springs to maintain constant force against test probes. The series is engineered for high-cycle durability, making it suitable for automated testing equipment where repeated insertion and removal occur frequently without degradation of contact quality.

Headers, Receptacles, Female Sockets Replacement Considerations

Compatible substitutes include other Mill-Max 399 series targets with matching 32-position counts and 2.54mm pitch, such as the 399-41-032-10-xxxxxx variants if tin plating is acceptable. Verify that alternative parts maintain the same right-angle orientation and through-hole termination style to ensure mechanical compatibility with existing test fixtures.
