32KHz quartz in smaller package

[NicolasVoirol]

Dear Nordic Team,

We have a running product that is using 32KHZ quartz from MicroCrystal : https://www.microcrystal.com/fileadmin/Media/Products/32kHz/Datasheet/CM7V-T1A.pdf

Due to available space in our new product we would like to switch to a smaller package (CM8 or CM9, still from MicroCrystal)

     CM8 : https://www.microcrystal.com/fileadmin/Media/Products/32kHz/Datasheet/CM8V-T1A.pdf

     CM9 : https://www.microcrystal.com/fileadmin/Media/Products/32kHz/Datasheet/CM9V-T1A.pdf

Do you see any problem (power consumption increase, stability, etc ...)  of using these smaller quartz ?

I'm looking forward to hearing from you soon.

Best regards

Nicolas

As long as the crystal parameters meet the listed requirements in the datasheet they can be used without any issue: https://infocenter.nordicsemi.com/topic/ps_nrf52840/clock.html#unique_554427417

In general a low load capacitance will reduce both start up time and current consumption.
