Headers, Male Pins Procurement Notes

Verify that the specific ordering suffix matches the required termination style and polarization configuration. Confirm compliance with environmental standards such as RoHS if applicable to the project requirements. Ensure compatibility with mating receptacles within the same R Series family. Validate thermal performance against the maximum operating temperature limits specified in the datasheet before finalizing procurement.

Headers, Male Pins Selection Notes

Select this model when a high-density interconnect solution is required for rigid board-to-board connections. The right-angle design facilitates compact packaging in constrained chassis environments. Consider the 300-position count and four-row layout for complex signal routing needs. Ensure the through-hole process capability aligns with the manufacturing assembly line specifications.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding industrial and defense sectors.
