Verification of Crystal suitability for STM32WL design

[DRoss.3]

We have a design implementing the STM32WL55/WE5.

The recommended crystals on the reference designs and literature are:

NX2012SA 32.768KHz EXS00A-MU00527X2

NX2016SA 32MHz EXS00A-CS06465

I want to verify that it is OK to use the following:

For NX2016SA:  EIIECS-320-10-37B-CKY-TR

CRYSTAL 32.0000MHZ 10PF SMD ESR 50 ±10ppm ±10ppm -30 ~ 85 2.0x1.6x0.45mm

For NT2016SF-32M-END5875A:  EIIECS-TXO-20CSMV-320-EY-TR

MultiVoltTCXO,32MHz,±2.5ppm,1.7V~3.465V,2.5mA,-30°C~85°C,ClippedSineWave

The design must comply with SigFox and LoRa spec and will potentially be in field for a long time (10+ years).

Datasheets attached.
