Headers, Male Pins Procurement Notes

Verify current availability status directly with authorized distributors or Molex, as this item may be subject to factory special order constraints. Confirm RoHS compliance details and specific manufacturing lot dates prior to procurement. Ensure that the ordering suffix matches the required termination and contact configuration exactly to avoid integration errors in critical assemblies.

Headers, Male Pins Selection Notes

Select this model when a high-density, three-row interconnection solution is required for rigid PCB mounting. The 47-position count and 1.91 mm pitch suit applications needing substantial I/O in constrained spaces. Consider the through-hole termination method for robust mechanical stability. Verify that the straight orientation and mounting ear requirements align with the chassis or panel layout constraints of the target system design.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding environments. The series is characterized by its durability and adherence to strict military standards. As a product of Molex / AirBorn, it integrates advanced material science with precision engineering to ensure long-term reliability in vibration-prone and thermally variable operational contexts.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 47-position count, three-row configuration, and 1.91 mm pitch. Compatible replacements should maintain the same MIL-DTL-55302 compliance level and through-hole termination style. Cross-reference with other manufacturers' MIL-spec rectangular plugs only if dimensional and electrical parameters are identical.
