Headers, Male Pins Procurement Notes

Verify the specific datasheet version for the RM412-300-171-9000 to confirm exact termination tail length and guide pin configuration. Ensure compatibility with mating receptacles in the same R Series family. Confirm that the gold plating specification meets the environmental requirements of the target application before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this model when a high-density 300-position connection is required in a compact form factor. The 1.91 mm pitch allows for significant circuit density while maintaining standard spacing. Choose this variant over surface mount options if through-hole reliability is preferred for vibration-prone environments. Verify that the straight mounting style aligns with the mechanical constraints of the enclosure design.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors designed for demanding applications. The series is known for its compliance with strict military standards, ensuring high reliability in harsh conditions. The RM412 prefix typically denotes a specific housing style and contact arrangement within the broader product portfolio managed by Molex / AirBorn.

Headers, Male Pins Replacement Considerations

Direct substitutes must match the 300 position count, 1.91 mm pitch, and MIL-DTL-55302 compliance. Verify that any replacement part maintains the same through-hole termination and gold contact plating. Cross-reference the mounting ear configuration and guide pin setup to ensure mechanical interchangeability without redesigning the PCB footprint.
