Basic Reliability Prediction (MTBF Calculation)
RAM Commander software prediction module is a reliability tool providing everything
necessary for primary reliability prediction (MTBF or failure rate
prediction/calculation) based on one of the prediction models for electronic and
mechanical equipment.
It contains more than
30 reliability prediction methods,
including the latest methods like FIDES 2009 and 217 Plus:
Electronic components reliability prediction methods:
MIL-HDBK-217E-1 P. stress
MIL-HDBK-217F-1 P. count

RAM Commander reliability module supports 'one-click' automatic switch between different
prediction methods.
Each method defines a set of component parameters which should be defined in order
to calculate its reliability:
To make the management of these complex data more convenient and easy, different
reliability libraries are available.
Components Library
RAM Commander contains built-in electronic components library. SoHaR supplies the
library containing hundreds of thousands (total number of records is currently 410,000 and the number is growing)
of widely used electronic components by the world leading manufacturers continually
updated by RAM Commander team adding more manufacturer's data on a monthly basis.
Customers may update the library - both manually and by importing components data.
Part Number Recognition
Leading manufacturers use special algorithms naming their parts. RAM Commander implements
these algorithms for the opposite direction in order to get reliability data from
Part Number. Our reliability software supports algorithms for decoding
Part Numbers of passive components (Resistors and Capacitors) of the following manufacturers:
AVX, ATC, Bourns, Cal-chip, DALE, Hitano, Garrett, IRC, Johanson, Kemet, KOA, Kyocera,
Mallory, Meritek, Murata, MSI, NIC, Nichicon, Novacap, Samsung, Siemens, Syfer,
OhmCraft, Paccom, Philips, Phycomp, Ralec, ROEDERST, TDK, TaiyoYuden, Vishay, Roedenstein,
Vitramon, Yageo.
GPRD Library
Additional reliability data library available for users is GPRD (General Part Reliability
Data) which is used to store manufacturers' provided or field reliability data (obtained
from FRACAS or another source).
Use of described above reliability prediction methods, reliability libraries and
convenient project tree building and management utilities makes RAM Commander reliability
prediction module a must-have tool for reliability engineering.
As a result of reliability prediction performed is a report with a breakdown of
MTBF figures per system, unit, board and component levels:
Obtained failure rates are then used in reliability and availability analysis using
Temperature Curve, Mission Profile, Pareto and other tools - see
Reliability & Availability Analysis Software Module.
