Headers, Male Pins Procurement Notes

Verify the specific termination material configuration against project requirements, as this part specifies pre-tinned tin/lead alloy for the tail length. Confirm that the vertical orientation and mounting ear dimensions align with the target PCB layout constraints. Ensure compliance with applicable environmental regulations regarding lead content if RoHS exemption or alternative materials are mandated for the final assembly process.

Headers, Male Pins Selection Notes

Select this model when a high-density 122-position vertical plug is required for MIL-DTL-55302 compliant designs. The choice is driven by the need for through-hole mounting with integrated mounting ears to reduce mechanical stress on the board. Consider the 1.91 mm pitch and three-row configuration for space-constrained applications needing substantial I/O capacity within a standard rectangular form factor.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, a line of rectangular connectors known for durability in harsh environments. The series offers various configurations including straight and right-angle options across multiple row counts. The RM312-122-102-5501 specifically addresses the need for vertical board mounting with a high circuit count, serving as a critical interface point in complex electronic assemblies where signal integrity and mechanical robustness are paramount.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other R Series plugs with matching 122 positions and 3-row layouts, such as RM312-122-102-5500, provided the termination material differences are acceptable. Verify that any replacement maintains the same MIL-DTL-55302 compliance and physical dimensions to ensure interchangeability without modifying the host PCB design.
