**Hello everyone,**

While reviewing the _LimeSDR-Mini\_2v4_ design, I found that the **TCXO (40 MHz, HCMOS, 3.3 V, 0.5 ppm, –40 to +85 °C, ±15 ppm, 5.0 × 3.2 mm)** — **Part Number E7355LF** from **Rakon** , listed in the BOM is currently **unavailable in the market**.

Has anyone else encountered this issue?  
Could you please suggest how we can source it or if there is an **equivalent alternate TCXO** that can be used instead?

**Thank you.**

It could be that it’s a special order item. Have you damaged this part?

Hello,  
We are currently **developing a custom board based on the LimeSDR open-source hardware design**.  
While reviewing the **LimeSDR-Mini\_2v4 BOM** , we found that the **Rakon E7355LF TCXO** is no longer available through standard distributors.  
Could you please confirm whether this is a **special-order component** , and if there is a **recommended equivalent or compatible alternative** that can be used in its place?

Thank you.

Yes, it is special order from Rakon.

You should select TCXO according to your application. I have no alternative to suggest, sorry.
