• General purpose circuit board interconnections

Headers, Male Pins Procurement Notes

Verify the specific suffix codes against official TE Connectivity documentation to confirm exact pin count, orientation, and material specifications. Ensure compatibility with mating connectors within the RAST 5 family. Confirm that the through-hole footprint matches the target PCB design requirements before finalizing procurement orders.

Headers, Male Pins Selection Notes

Select this component when a robust, vertically mounted header with a 5mm pitch is required. The RAST 5 series offers reliable mechanical locking and high current carrying capacity suitable for power and signal applications. Consider the glow wire rating if the application demands strict flammability compliance in enclosed environments.

Headers, Male Pins Part Context

This part belongs to the widely adopted RAST 5 series, known for its secure locking mechanisms and versatility in various electronic assemblies. The 5-position configuration provides a compact solution for multi-conductor connections while maintaining structural integrity through its reinforced thermoplastic housing and standardized terminal interfaces.

Headers, Male Pins Replacement Considerations

Direct substitutes include other 5-position RAST 5 headers from TE Connectivity. Verify identical pitch, mounting style, and housing color if visual identification is critical. Cross-reference mating plugs to ensure mechanical and electrical compatibility without redesigning the PCB layout.
