What are the key features of HYT221?

Humidity/temperature sensing module for environmental measurement designs
4-pin connection count for compact PCB integration
Listed analog-circuit record with 2017-08-18 introduction date
Obsolete YTEOL 0 status for lifecycle and replacement planning
Peak reflow temperature and reflow time require project-level process confirmation

What is HYT221 used for?

HYT221 is used in environmental monitoring nodes, HVAC controls, data loggers, and industrial equipment that need humidity/temperature feedback in a compact sensor assembly. Because the record is obsolete and reflow data is not specified, it is most appropriate for maintenance, redesign matching, and controlled legacy sourcing rather than new platform selection.

Frequently Asked Questions

Which environmental measurement designs are a practical fit for HYT221?

HYT221 is suitable for humidity/temperature sensing positions in monitoring nodes or HVAC controls where a compact 4-pin sensor module can be integrated on the PCB.

How should lifecycle status affect sourcing decisions for this IST part?

The record shows obsolete status and YTEOL 0, so buyers should verify lot traceability, approved substitutes, and the 4-pin connection before authorizing production use.

What assembly information needs extra review before approving HYT221 stock?

Peak reflow temperature and time are not specified in the record, so process engineers should qualify soldering conditions for the 4-pin device before build release.
