This is a **NIHON DEMPA KOGYO** Oscillator. These are the [possible options](https://www.digikey.com/en/products/filter/oscillators/172?s=N4IgjCBcpgbFoDGUBmBDANgZwKYBoQB7KAbRACZyAOAZgBZyQBdAgBwBcoQBldgJwCWAOwDmIAL4FyYAKwAGBCGSR02fEVIga5AAQBZABIAvZm06QQAVSED2AeRR6caLAFc%2BOCQQC0EaEtRMXAJiSDJYOjpmSRBvRn9lfld1ULIZaJj4skIsRAEMDDR2Qj5ooA) that I found that might work as replacement.

Hi [homestyle.nz](https://forum.digikey.com/u/homestyle.nz),

I suspect that you have a crystal rather than an oscillator, based on the markings.

It’s likely one of the [these](https://www.digikey.com/short/wrz3p139) crystals from the NDK NX3225SA series.

From the NX3225SA series [datasheet](https://www.ndk.com/en/products/upload/lineup/pdf/NDKX03-00010_en.pdf):

I don’t know which, if any of the options we carry is the right match for you, as they don’t give decoding info for the various options from the markings. However, some of these are designed to work with particular RF IC’s. If you know what RF IC this is next to on your circuit board, we might be able to make an educated guess as to which one would likely be the best option.
