Headers, Male Pins Procurement Notes

Verify the specific contact count and row configuration against project requirements before ordering. Confirm that the through-hole mounting style aligns with the target PCB layout and manufacturing capabilities. Ensure compatibility with mating connectors within the same M50 series family to maintain mechanical and electrical integrity during assembly.

Headers, Male Pins Selection Notes

Select this component when a high-pin-count, low-profile connection is required on dense circuit boards. The 1.27 mm pitch allows for significant I/O density in limited space. Consider the operating temperature range and current rating to ensure suitability for the specific electronic environment. Verify housing material properties if exposure to harsh chemicals or extreme heat is anticipated.

Headers, Male Pins Part Context

This connector belongs to the Archer M50 series, which is engineered for compact, high-reliability applications. The series offers various configurations including headers, receptacles, and IDC options. Standardized dimensions and mating interfaces allow for flexible system design across different product lines while maintaining consistent performance standards.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other Harwin M50 series headers with matching 1.27 mm pitch and through-hole termination. Ensure any replacement maintains identical contact count, row arrangement, and housing material specifications to preserve mechanical fit and electrical performance.
