Procurement Notes

Verify the specific ordering suffix matches the required package variant and screening level. Confirm RoHS compliance status with the supplier. Check for advanced screening options if high-reliability requirements exist. Ensure the TO-71 lead form matches assembly needs. Validate datasheet revisions before finalizing procurement.

Selection Notes

Select this component when dual N-channel JFETs are required in a hermetic metal can package. Consider the 60 V breakdown voltage and 0.5 mA current limits for circuit design. Evaluate the 10 pF input capacitance for high-frequency response requirements. Compare against other LS840 series variants like LS842 or LS845 for pinout or parameter differences.

Part Context

The LS840 belongs to the LS840 Series of dual N-channel JFET amplifiers from Linear Integrated Systems. This series is available in multiple packages including TO-71, TO-78, PDIP, and SOIC. The TO-71 variant provides a hermetic metal case option. Other models in the series may offer different electrical characteristics or screening levels.

Replacement Considerations

Check for direct substitutes within the LS840 series such as LS842 or LS845. Verify pin compatibility and electrical parameter overlap. Consult manufacturer cross-reference guides for approved replacements. Ensure replacement parts meet the same RoHS and environmental standards.
