Headers, Male Pins Procurement Notes

Verify the specific part number suffix against official Harwin documentation to confirm exact pin count and orientation. Ensure compatibility with standard SMT reflow profiles and check for RoHS compliance status through certified datasheets before procurement.

Headers, Male Pins Selection Notes

Select this component when a low-profile, high-density connection is required. The 1mm pitch allows for significant I/O density within limited board space. Verify that the horizontal mounting style aligns with the mechanical constraints of the final enclosure design.

Headers, Male Pins Part Context

This connector belongs to the M40 series, which is characterized by fine-pitch capabilities and robust construction. The series is widely utilized in consumer electronics and industrial equipment where space efficiency and reliable signal transmission are critical requirements for modern miniaturized designs.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 1.00 mm pitch, 20-position count, and SMT horizontal form factor. Consult Harwin's official cross-reference guides for verified alternative part numbers within the same product family.
