Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pin count, row configuration, and termination style. Ensure compatibility with mating female connectors within the same Archer Kontrol family. Check RoHS compliance status and material safety data sheets for regulatory requirements in target markets. Confirm package quantity specifications match production needs.

Headers, Male Pins Selection Notes

Select this component when a 20-position, 1.27 mm pitch vertical header is required for space-constrained designs. Consider the 8.25 mm stacking height for layer clearance. Evaluate thermal performance limits against operational environment constraints. Compare against alternative Harwin models like M55-6002042R if female connectivity is needed instead.

Headers, Male Pins Part Context

This part belongs to the Harwin M55 Archer Kontrol family of high-density board-to-board connectors. The series offers various position counts and orientations to support modular electronic architectures. It complements matching female sockets and right-angle variants for complete interconnect solutions.

Headers, Male Pins Replacement Considerations

Direct substitutes within the same series include M55-7002042R variations with different pin counts or mating lengths. Cross-reference with M55-6002042R only if female polarity is acceptable. Verify mechanical dimensions and electrical ratings before substituting with non-Harwin components.
