EPRD 2014 Introduction 1 1, 1 0 INTRODUCTION, This document represents a major update to the previous Electronic Part Reliability Data EPRD 97. databook published over 15 years ago Its purpose is to provide empirical field failure rate data on. electronic components EPRD 97 data was limited to Capacitors Diodes Integrated Circuits. Optoelectronic Devices Resistors Thyristors Transformers and Transistors EPRD 2014 adds millions. of hours of operating time and hundreds of failures to these component types as well as adding and. updating field failure rate data on electronic Connectors Relays Switches Inductors Coils previously. contained only in the Reliability Information Analysis Center RIAC Nonelectronic Part Reliability Data. NPRD 2011 release, Reliability data is required to perform reliability assessments of systems The part types for which data. is contained in this document are those contained in existing reliability prediction methodologies such as. MIL HDBK 217F Notice 2 and Whereas MIL HDBK 217 and 217PlusTM contain mathematical models. that have been derived from empirical field failure rate data the data contained in EPRD 2014 represents. historically observed field failure rates This data can be used as an alternative to existing prediction. methodologies, Commercial quality components continue to be widely used in many applications including military. systems Much of the data contained in this document relates to commercial quality components It can. therefore be used to predict reliability for both commercial and military systems containing commercial. quality components, EPRD 2014 in combination with NPRD 2011 provides the capability of estimating the reliability of.
most component and assembly types used in electronic or mechanical systems. 1 1 Background, Accurate and timely reliability predictions are an important part of a well structured reliability program. If properly performed they can provide insight into the design and maintenance of reliable systems as. well as provide initial estimates for sparing requirements. A potential use for this document is to complement existing reliability prediction methodologies by. providing failure rate data in a consistent format on various electronic component types when an. organization does not have its own database of failure rates for its own products systems Although the. data contained in this publication was collected from a wide variety of sources the RIAC has carefully. and systematically screened the data such that only high quality data is added to the database and. presented in this document In addition only field failure rate data has been included. The user of this document should note that the use of reliability prediction techniques such as 217PlusTM. or MIL HDBK 217 or the use of the data contained in EPRD 2014 should complement and must not. replace sound reliability engineering and design practices This document is meant to provide historical. reliability data on a wide variety of components to aid engineers in estimating the reliability of systems. Sound reliability engineering practices must include knowledge of the failure physics of all components. modules and interconnection assemblies in a system Knowledge of life limiting failure mechanisms. and how these mechanisms will behave in the intended use environment is also necessary Only in this. manner can robust designs be ensured, The intent of this introductory section is to provide the user with information to adequately interpret and. use the data Since the primary purpose of this document is to augment reliability prediction. methodologies such as 217PlusTM and MIL HDBK 217 a brief background of MIL HDBK 217 will be. given along with a description of how the data in this document can be used to augment it. 100 Seymour Rd Suite C101 Utica NY 13502 1311 Ph 877 808 0097. 1 2 Introduction EPRD 2014, WHAT IS THE PURPOSE OF PERFORMING A RELIABILITY PREDICTION 1. Predictions have several purposes among them are, 1 feasibility evaluation. 2 comparing competing designs, 3 identification of potential reliability problems.
4 to provide reliability input to other R M tasks, Feasibility evaluation involves evaluating the compatibility of a proposed design concept with the design reliability. requirements Early in the system formulation process a feasibility evaluation would typically take the form of a parts count. type prediction MIL HDBK 217F Appendix A to determine ballpark compatibility with required reliability Feasibility. evaluation may also take the form of a detailed parts stress type analysis MIL HDBK 217F Sections 5 23 for components. used in very high quantities One example might be for phase shifter modules on a phased array antenna Feasibility. evaluation is much more critical for totally new design concepts where no similar earlier system exists than for systems with. known reliability performance, Comparing competing designs is similar to the feasibility evaluation except that it extends through the design process and. provides one input the predicted reliability to be used in making broader system level design trade off decisions involving. factors such as cost weight power performance etc A parts stress type prediction is typically refined to provide a. quantitative means of estimating the relative cost benefit of these and other system level trade off considerations. Predictions which are properly performed provide a methodical means of checking all components for potential reliability. problems By focusing attention on lower quality over stressed or misapplied parts a relative means of evaluating the. reliability impact of these potential problem areas can be performed It should be emphasized that the prediction itself does. not improve system reliability it only provides a means for identifying potential problems that if corrected will lead to. improved systems reliability Therefore predictions provide an excellent vehicle for government contractor dialog in. reviewing and evaluating the progress of the design prior to testing. Predictions provide key input to other R M tasks such as maintainability analysis testability evaluation and failure modes and. effects analysis FMEA Because predictions identify areas of relatively low reliability they provide key input to weigh the. benefits of adding test points making areas more readily accessible for maintenance or adding redundancy to reduce the effect. of a particularly critical failure mode, WHAT IS THE PURPOSE OF MIL HDBK 217. MIL HDBK 217 is intended to provide a consistent and uniform data base for making reliability predictions when no. substantial reliability experience exists for a particular equipment It contains two basic methods of calculating component. level failure rates the parts stress method and the parts count method The parts count method requires only limited. information such as component type complexity and part quality to calculate a part failure rate The parts count section of the. handbook is derived by assigning model factors for more involved part stress method to slightly conservative estimates of what. would typically be expected All of the specific default values are provided in Appendix A of the handbook The parts stress. method requires significantly more information such as case or junction temperature and electrical operating and rated. conditions to perform a failure rate calculation Prior to the development of the handbook each contractor would have its own. unique set of data of which the source would have to be fully understood before meaningful design comparisons could be. It is not feasible for documents like 217PlusTM MIL HDBK 217 or other prediction methodologies to. contain failure rate models on every conceivable type of component and assembly Traditionally. reliability prediction models have been primarily applicable only for generic electronic components. Therefore EPRD 2014 serves a number of different needs such as. 1 Provide failure rate data on commercial quality components. 2 Provide failure rates on components in cases where data or analyses are not otherwise. available feasible or required, excerpt from the Reliability Analysis Center RAC April 1990 Newsletter Technical Brief written by Seymour Morris of Rome Laboratory. Quanterion Solutions Incorporated, EPRD 2014 Introduction 1 3.
3 Complement 217PlusTM MIL HDBK 217 and other prediction methodologies by providing. data on part types not addressed by their respective models. 1 2 Data Collection, The failure rate data contained in this document represent a cumulative compilation from the early 1970 s. through July 2013 However it should be noted that data is periodically purged from the database in the. event that newer data of higher quality is obtained The RIAC is continuously soliciting new field data in. an effort to keep the databases current The goals of these data collection efforts are to. 1 Obtain data on relatively new part types and assemblies. 2 Collect as much data on as many different data sources application environments and. quality levels as possible, 3 Identify as many characteristic details as possible including both part and application. parameters, The RIAC utilized the following generic sources of data for EPRD 2014. Published reports and papers, Data collected from government sponsored studies. Data collected from military maintenance data collection systems. Data collected from commercial warranty repair systems. Data from commercial industrial maintenance databases. Data submitted directly to RAC from military or commercial organizations that maintain failure. Brief descriptions are provided of the sources utilized in this document Each summarized failure rate.
