Xinghua Huayu Electronics Co., Ltd. Component Intelligence

PartGenie provides a searchable manufacturer part catalog when source catalog data is available; this hub is the intelligence and navigation layer that summarizes HYDZ product families, sourcing checks and comparison paths.

Start with the functional role, because one part may be a transmitter and another a receiver. Then compare center frequency, sensitivity, package dimensions, pin spacing, operating temperature and the acoustic test conditions in the datasheet.

They should be treated as functional alternatives unless the datasheets prove the same mechanical outline, electrical ratings, acoustic output and mounting constraints. Enclosure design and drive waveform can affect the final sound level.
