E. Define Component, Spare Part, Subsystem, and No or Negligible Value

Comment: Three respondents requested that the terms "component" and "spare part" be defined. Two respondents requested that the phrase "no or negligible value" be defined and clarified and one respondent requested that the term "subsystem" be defined.

DoD Response: The term "component" is defined at FAR 2.101. The term "spare part" is a commonly used term understood to mean any item that is supplied as a replacement part of an end item. The term "subsystem" is also a commonly used term throughout the FAR and DFARS that denotes a functional grouping of lower-tier components that combine to perform a major function within an end item, such as electrical power, altitude control, or propulsion. DoD maintains that the phrase "no or negligible value" is self-explanatory and does not require further clarification.
