Headers, Male Pins Procurement Notes

Verify the specific termination type and guide pin configuration against the official datasheet, as the RM412 series includes variations such as unassembled polarized pins or fixed jacksets. Confirm RoHS compliance status and lead time requirements directly with Molex/AirBorn distributors, as this item may be subject to factory special order constraints. Ensure the selected variant matches the required circuit count and tail length for the target PCB layout.

Headers, Male Pins Selection Notes

Select this model when a high-density 276-position connection is required within strict MIL-DTL-55302 form factors. The 1.91 mm pitch allows for compact board integration while maintaining robust mechanical locking. Consider the PPS housing material for environments requiring resistance to high temperatures up to 125°C. Verify that the straight plug orientation aligns with the chassis or backplane mounting geometry of the assembly.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors manufactured by Molex under the AirBorn brand. The series is widely recognized for its use in harsh environments across defense and aerospace sectors. The RM412 designation specifically indicates a board mount plug configuration within this standardized family, ensuring interchangeability with other components adhering to the same dimensional and performance standards.

Headers, Male Pins Replacement Considerations

Direct substitutes must adhere to MIL-DTL-55302 specifications with identical 276 position counts and 1.91 mm pitch. Cross-reference compatible part numbers within the AirBorn RM412 family for variations in termination style or guide pin assembly. Ensure any replacement maintains the same current rating and temperature range to preserve system integrity.
