Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Samtec documentation to confirm contact plating and housing variations. Ensure compatibility with standard pick-and-place equipment due to the tube packaging format. Confirm that the target PCB footprint matches the specified right-angle surface mount dimensions before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this model when a 44-position dual-row header is required for space-constrained designs. The 2.00 mm pitch offers a balance between density and manufacturability. Choose this variant over through-hole options for improved mechanical stability during reflow soldering processes. Verify that the mating connector system accepts the specified .020 inch square pins.

Headers, Male Pins Part Context

This component belongs to the MMT series of mixed technology headers from Samtec. The series is characterized by its ability to mate with various terminal types while maintaining a compact profile. The MMT line supports both vertical and horizontal mounting orientations, providing flexibility for diverse enclosure constraints and routing requirements.

Headers, Male Pins Replacement Considerations

Direct substitutes include other Samtec MMT series variants with matching position counts and pitch specifications. Cross-referencing part numbers such as MMT-122-02-TM-DH-K requires verification of contact material differences. Always validate mechanical dimensions and electrical ratings before substituting components in existing designs.
