Headers, Male Pins Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact contact finish, termination style, and mounting variations. Ensure compatibility with mating receptacles or plugs within the same R Series family. Confirm RoHS compliance status if required by project specifications. Cross-reference the Mouser part number 479-RM2521003125500 for accurate distributor identification.

Headers, Male Pins Selection Notes

Select this model when a 100-position, three-row connector is necessary for space-constrained designs. The 1.91 mm pitch allows for dense circuit layouts while maintaining robust mechanical integrity. Consider the right-angle orientation and through-hole mounting requirements during PCB layout. Verify that the 3 A current rating per contact aligns with the system's power distribution needs.

Headers, Male Pins Part Context

This component belongs to the AirBorn R Series, which offers versatile rectangular connectors ranging from 10 to 604 contacts. The series supports two to six row configurations with various pitch options including 0.025, 0.050, 0.075, and 0.100 inches. The R Series is widely used in aerospace and defense sectors due to its adherence to strict military standards and high reliability under harsh conditions.

Headers, Male Pins Replacement Considerations

Equivalent parts must match the MIL-DTL-55302 standard, 100-position count, three-row layout, and 1.91 mm pitch. Verify identical mounting style and termination method to ensure physical compatibility. Check for matching voltage and current ratings to maintain system safety margins.
