I am a new user of the 217Plus norm. During the categorization process I have experienced some problems concerning a few parts. To which category can I add the following parts:

– DIODE TRANSIL (….wukierunkowe/#)
Diode, Low Frequency, Array / Diode, Low Frequency, Transient Suppressor?

– ESD PROTECTION DIODE (…22?Ntt=1603422)
Diode, Low Frequency, Array?

-IC, ADC CONVERTER (…sop/dp/1607231)
Is it IC, Digital, Plastic or IC, Linear, Plastic?

Furthermore, I have troubles with categorization of the components:

1. Jumper: JUMPER-2.0/B -TME…lkowe/ninigi/#
Connector, Rectangular ?

2. Battery holder for battery CR2032: SN2032SN-LF — Martiex…nd=SN2032SN-LF

3. Suppression Filter: NFE61PT472C1H9L – Fernell…nal/dp/9528229

4. FUSES SMD: BSMD-T1.0A — TME…siba/1580001/#

5. Quartz crystal SMD: QSD12M000 – Maritex

6. Quartz Crystal SMD with Capacitor: 12.00M-12SMXR — TME…f-xtal026384/#

I am a little bit experienced with the method MIL-HDBK-217F which includes both components of Quartz crystal type and Fuses. Can I use data from MIL-217F while performing calculations of lambda_IA using method 217Plus for fuses and quartz crystals? If yes, how should I do this? For instance FUSES MIL-217F present the following model:

Lambda=base_failure_rate*environmental_factor*qual ity_factor

The problem is that 217Plus does not include a quality factor and on the level of Lambda_IA this method does not take into account an environmental factor. How can I cope with that?
I do not use any software (just the norm).
