Procurement Notes

Verify the specific suffix 'X' against official documentation to confirm reel packaging specifications. Ensure the part number matches the exact manufacturer designation, as Fairchild products are now managed under ON Semiconductor nomenclature. Confirm RoHS compliance status and lead-free certification details directly from the current datasheet before procurement.

Selection Notes

Select this component when a precise 5 V reference is required in space-constrained designs. The SOT-23 package offers a small footprint suitable for portable electronics. Verify that the operating temperature range meets the environmental requirements of the target application. Consider the output voltage tolerance of ±1% for circuit accuracy calculations.

Part Context

This component belongs to the family of two-terminal voltage references produced by Fairchild Semiconductor. These devices serve as foundational elements in power management and signal conditioning circuits. The series is characterized by low cost and high reliability, widely used in consumer and industrial electronics where stable voltage levels are critical for proper system operation.

Replacement Considerations

Check for updated part numbers under ON Semiconductor following the corporate integration. Verify pinout compatibility and electrical parameters if substituting with other 5 V references. Ensure the replacement maintains the same package type and thermal characteristics.
