Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official Molex documentation to ensure correct polarization and guide set configurations. Confirm RoHS compliance status directly with the manufacturer, as historical data indicates variations within the series. Request current manufacturing lead times and obsolescence notices prior to finalizing procurement plans to avoid supply chain disruptions.

Headers, Male Pins Selection Notes

Select this model when a high-density, three-row interconnect solution is required for space-constrained applications. Ensure the mating receptacle shares the same 1.91 mm pitch and polarization index. Validate that the PCB layout supports the specified through-hole tail length and right-angle mounting orientation for proper mechanical alignment.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for harsh environments. The series is known for its durability and compliance with stringent military standards. The RM312 prefix typically denotes a specific size code and row configuration within the broader product family, distinguishing it from two-row or single-row variants.

Headers, Male Pins Replacement Considerations

Cross-reference part numbers sharing the same MIL-DTL-55302 specification and identical position counts. Verify that any substitute maintains the exact 1.91 mm pitch and right-angle geometry to ensure physical compatibility without modification.
