Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm that the component status aligns with project lifecycle requirements, as availability may vary. Ensure compatibility with existing PCB footprint dimensions for the 16-DIP configuration before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when a dedicated PIR controller with low power consumption is required for through-hole assembly. Compare the 100 µA supply current against system battery life requirements. Verify that the -25°C to 70°C operating range meets environmental conditions. Ensure the 16-pin DIP form factor fits the mechanical constraints of the target enclosure design.

Sensor And Detector Interfaces Part Context

This part belongs to the PT8A261/262 series of PIR sensor light switch controllers produced by Diodes Incorporated. It shares functional similarities with other members of the family but is distinguished by its specific packaging and suffix designation. The series targets cost-effective motion sensing solutions for residential and commercial lighting applications.

Sensor And Detector Interfaces Replacement Considerations

Check for pin-compatible alternatives within the same product family if the exact suffix is unavailable. Verify that any substitute maintains the 16-DIP package and similar electrical characteristics. Consult the manufacturer's latest replacement guide for officially confirmed cross-reference parts.
