To provide a new easy way of identifying **[Fox Electronics](https://www.digikey.com/en/supplier-centers/f/fox-electronics)** products, Fox Electronics has changed to a new part numbering format.  
For Example, the part **[F32K-327](https://www.digikey.com/product-detail/en/fox-electronics/FO3HFCOM0.032768-T1/631-1260-2-ND/2509441)** is an F32K model number at 32.768KHz. In the new part number format, the part number is **[FO3HFCOM0.032768-T1](https://www.digikey.com/product-detail/en/fox-electronics/FO3HFCOM0.032768-T1/631-1260-2-ND/2509441)**

- please note that the frequency in this new part number format must have at least one digit before and one digit after the decimal; once this is met, then it is written to the least significant digit and always written in MHz.

T1 = 1,000 piece reel T2 = 2,000 piece reel T3 = 3,000 piece reel T5 = 5,000 piece reel They also have suffixes for bulk parts. BAG100 = 100 piece bag BAG200 = 200 piece bag BAG1k = 1,0…
