Headers, Male Pins Procurement Notes

Verify manufacturing origin and compliance documentation prior to order placement. Confirm that the specific suffix matches project requirements, as variations may exist within the series. Request updated datasheets to ensure alignment with current revision levels. Validate environmental certifications against system specifications. Ensure storage conditions meet manufacturer guidelines to preserve contact integrity before assembly.

Headers, Male Pins Selection Notes

Select this model for applications requiring high-density vertical interconnects under strict environmental conditions. The 1.91 mm pitch supports compact PCB layouts while maintaining signal isolation. Gold plating ensures reliable performance in corrosive environments. Verify that the 3-row configuration fits within available board space constraints. Consider thermal management capabilities given the PPS material properties and operating temperature range.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding industrial and defense applications. The series emphasizes durability and consistent electrical performance across extreme temperatures. The RM312 variant specifically addresses board-mount needs with vertical orientation options. Integration into larger assemblies typically involves mating with corresponding receptacles from the same series family.

Headers, Male Pins Replacement Considerations

Cross-reference with other R Series part numbers for compatible mating interfaces. Verify pin count and row configuration match existing designs. Check termination type compatibility with PCB fabrication processes. Ensure dimensional tolerances align with enclosure cutouts.
