EPRD-20141.0Introduction1-1INTRODUCTIONThis 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 onelectronic components. EPRD-97 data was limited to Capacitors, Diodes, Integrated Circuits,Optoelectronic Devices, Resistors, Thyristors, Transformers, and Transistors. EPRD-2014 adds millionsof hours of operating time and hundreds of failures to these component types, as well as adding (andupdating) field failure rate data on electronic Connectors, Relays, Switches, Inductors/Coils, previouslycontained 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 datais contained in this document are those contained in existing reliability prediction methodologies, such asMIL-HDBK-217F, Notice 2 and. Whereas MIL-HDBK-217 and 217PlusTM contain mathematical modelsthat have been derived from empirical field failure rate data, the data contained in EPRD-2014 representshistorically observed field failure rates. This data can be used as an alternative to existing predictionmethodologies.Commercial quality components continue to be widely used in many applications, including militarysystems. 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 commercialquality components.EPRD-2014, in combination with NPRD-2011, provides the capability of estimating the reliability ofmost component and assembly types used in electronic or mechanical systems.1.1 BackgroundAccurate 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, aswell as provide initial estimates for sparing requirements.A potential use for this document is to complement existing reliability prediction methodologies byproviding failure rate data in a consistent format on various electronic component types when anorganization does not have its own database of failure rates for its own products/systems. Although thedata contained in this publication was collected from a wide variety of sources, the RIAC has carefullyand systematically screened the data such that only high quality data is added to the database andpresented 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 217PlusTMor MIL-HDBK-217, or the use of the data contained in EPRD-2014, should complement (and must notreplace) sound reliability engineering and design practices. This document is meant to provide historicalreliability 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 thismanner can robust designs be ensured.The intent of this introductory section is to provide the user with information to adequately interpret anduse the data. Since the primary purpose of this document is to augment reliability predictionmethodologies such as 217PlusTM and MIL-HDBK-217, a brief background of MIL-HDBK-217 will begiven, 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 IntroductionEPRD-2014WHAT IS THE PURPOSE OF PERFORMING A RELIABILITY PREDICTION?1Predictions 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 tasksFeasibility evaluation involves evaluating the compatibility of a proposed design concept with the design reliabilityrequirements. Early in the system formulation process a feasibility evaluation would typically take the form of a parts counttype prediction (MIL-HDBK-217F, Appendix A) to determine "ballpark" compatibility with required reliability. Feasibilityevaluation may also take the form of a detailed parts stress type analysis (MIL-HDBK-217F, Sections 5-23) for componentsused in very high quantities. One example might be for phase shifter modules on a phased array antenna. Feasibilityevaluation is much more critical for totally new design concepts where no similar earlier system exists than for systems withknown reliability performance.Comparing competing designs is similar to the feasibility evaluation except that it extends through the design process andprovides one input, the predicted reliability, to be used in making broader system level design trade-off decisions involvingfactors such as cost, weight, power, performance, etc. A parts stress type prediction is typically refined to provide aquantitative 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 reliabilityproblems. By focusing attention on lower quality, over-stressed or misapplied parts a relative means of evaluating thereliability impact of these potential problem areas can be performed. It should be emphasized that the prediction itself doesnot improve system reliability; it only provides a means for identifying potential problems that, if corrected, will lead toimproved systems reliability. Therefore, predictions provide an excellent vehicle for government/contractor dialog inreviewing 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 andeffects analysis (FMEA). Because predictions identify areas of relatively low reliability they provide key input to weigh thebenefits of adding test points, making areas more readily accessible for maintenance or adding redundancy to reduce the effectof 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 nosubstantial reliability experience exists for a particular equipment. It contains two basic methods of calculating componentlevel failure rates, the "parts stress method" and the "parts count method." The parts count method requires only limitedinformation such as component type, complexity and part quality to calculate a part failure rate. The parts count section of thehandbook is derived by assigning model factors for more involved part stress method to slightly conservative estimates of whatwould typically be expected. All of the specific default values are provided in Appendix A of the handbook. The parts stressmethod requires significantly more information such as case or junction temperature and electrical operating and ratedconditions to perform a failure rate calculation. Prior to the development of the handbook, each contractor would have its ownunique set of data of which the source would have to be fully understood before meaningful design comparisons could bemade.It is not feasible for documents like 217PlusTM, MIL-HDBK-217, or other prediction methodologies tocontain 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 components2. Provide failure rates on components in cases where data or analyses are not otherwiseavailable, feasible or required1excerpt from the Reliability Analysis Center (RAC) April 1990 Newsletter Technical Brief, written by Seymour Morris of Rome Laboratory.Quanterion Solutions Incorporated

EPRD-2014Introduction1-33. Complement 217PlusTM, MIL-HDBK-217 and other prediction methodologies by providingdata on part types not addressed by their respective models1.2 Data CollectionThe failure rate data contained in this document represent a cumulative compilation from the early 1970'sthrough July 2013. However, it should be noted that data is periodically purged from the database in theevent that newer data of higher quality is obtained. The RIAC is continuously soliciting new field data inan effort to keep the databases current. The goals of these data collection efforts are to:1. Obtain data on relatively new part types and assemblies2. Collect as much data on as many different data sources, application environments, andquality levels as possible3. Identify as many characteristic details as possible, including both part and applicationparametersThe RIAC utilized the following generic sources of data for EPRD-2014: Published reports and papersData collected from government-sponsored studiesData collected from military maintenance data collection systemsData collected from commercial warranty repair systemsData from commercial/industrial maintenance databasesData submitted directly to RAC from military or commercial organizations that maintain failuredatabasesBrief descriptions are provided of the sources utilized in this document. Each summarized failure ratecan be mapped to one of these data sources. An example of the process by which RIAC identifiescandidate systems and extracts reliability data on military systems is summarized in Table 1-1.Table 1-1: Data Summarization Procedure(1)Identify System Based On: Environments/QualityAgeComponent TypesAvailability of Quality Data(2)Build Parts List: Obtain Illustrated Parts Breakdown
